The totally underrated Digital Cushion: a horse owner’s guide


The digital cushion is  a major component of the  circulation and shock dissipation apparatus of the horse’s digit. It is a  elastic, wedge shaped mass composed of a fibrous fatty tissue that has the consistency varying between your earlobe and nose depending on it’s health. Ideally, the digital cushion takes up the majority of the rear 1/2 of the  hoof. It’s nestled underneath the deep flexor tendon, between the lateral cartilages, and above the frog.  The DC can be felt by pressing  between the bulbs of the heel. 

The DC  has sheet like ligaments that stretch from one  lateral cartilage to the one opposite, allowing for independent movement of the sides of the foot.  The digital tarus, part of the DC, originates from the underside of the coffin bone and deep digital flexor tendon and sends bands of fibrous tissue toward the heels  creating a a biologic lattice for the vasculature of the back half of the foot. There are also a series of trampoline-like ligaments traversing the inner surface of the frog, facilitating it’s expansion and contraction.

palmer hoof digital cushion

Horses have many ways to dissipate the concussion of moving at speed.  One way is by hemo-dynamic shock absorption in which the digital cushion plays an integral part. Let me explain:

During the swing phase of stride, blood is pulled into the extremities via centrifugal force. Upon the hoof landing, the fetlock descends. This drop causes the veins to close, trapping the blood within the hoof and dissipating shock like a waterbed. Much of this trapped blood is  in the matrix of tiny veins and capillaries running amongst the sub structures of the DC.  As the horse passes over the hoof, the fetlock rises and the blood-way is open. This built up pressure then shoots the de-oxygenated blood back up the leg, returned to the body and heart.

Venogram of the digit


It is important for the horseman to know that there is a wide range of variability when comparing DC between good and weaker footed horses. In a strong hoof, the ligaments of the DC are much thicker and the digital tarsus will have numerous fibrous connections .  The reasons for this are thought to be due to the presence of a highly adaptable myxoid  tissue in the region. Myxoid tissue is very adaptable and can become fibrous or cartilage. It is thought that the environment and how the foot is trimmed and/or shod can contribute to the makings of a robust foot.

Util recently, most discussions on hoof lameness were  limited to deterioration or injury to the navicular bone,  coffin bone, the deep flexor tendon, the navicular bursa, distal sesmodian (collateral) ligaments or the coffin joint capsule itself.

It is my belief that these structures are often damaged due to lack of a properly functioning digital cushion. Further, I believe that much of the objective of  best farriery practices is to be aware of the health of this underrated structure. In my practical experience I have come to believe that digital cushion is very adaptable, even in mature horses or ones with already compromised hooves, Horses that are well managed with plenty of exercise over varied terrain and shod or trimmed in a balanced manner will tend to have a more fibrous DC than horses that are kept up and not shod or trimmed well.

For more information on the Digital Cushion, I would like to recommend Epona TV’s 6 part series featuring Dr. Bowker.



Hoof Cracks: 3 Reasons your horse has them and how to get rid of them

Hoof Cracks: 3 reasons your horse has them and how to get rid of them

Cracked hooves are a common problem that can range from single, shallow, millimeter-wide groove that takes a good look to even notice, to multiple, full thickness splits of the hoof wall that cause lameness by pinching the sensitive structures beneath.  This article explains the causes of these ugly splits and how to reduce and possibly eliminate them through good hoof management strategies.

Note: this article does not deal with the less common “quarter crack“. Quarter cracks extend from the hairline down and are generally the result of chronic imbalance under extreme loads in performance horses. 

The dry hoof fallacy

This “dry hoof theory” is perpetuated by the plethora of hoof oils marketed to to heal split hooves. The ragged, shelly appearance of cracked hooves gives credence misconception that the hooves  lack moisture. Often, under the advice of an otherwise knowledgeable horse person,  attempts to hydrate the hoof  via overflowing water troughs, applying hoof creams, or old timey treatments, usually involving automotive fluids, are made.

Hoof cracks are actually the result of too much moisture. Wet  (anaerobic) conditions are a contributing factor for White Line Disease, the most common cause of hoof cracks . WLD describes a common fungal invasion of the hoof wall. For more on the causes, progression and identification of WLD, check out this.

How WLD causes hoof cracks

WLD fungi seek out deep, damp, airless cavities. Hooves with flares  or other damage to the hoof wall have voids in the hoof wall. These nooks will fill with muck, creating the ideal anaerobic conditions for this horn ingesting microbe to thrive.

Once the WLD has established itself deep within the hoof via the original defect, it will spread to the surrounding horn, eventually making its way to the surface as a hoof crack. The hoof splits from the inside out. This is why  WLD is impossible to eradicate  through topical treatments.

The black lines are evidence of WLD's presence deep within the hoof
The black lines are evidence of WLD’s presence deep within the hoof

Hoof cracks are remedied using a three step progress: address the underlying hoof balance issue, remove the affected, contagious horn and expose the area to air to eliminate anaerobic conditions that perpetuate this hoof funk.

Underlying causes of hoof cracks

1. Flares and hoof imbalance

The coffin bone is the core of the hoof which dictates the shape and size of the capsule that forms around it.  Viewed externally, the hoof wall should slope evenly away from the coronary band so that shape of the bottom hoof should echos that of the coronary band.

Ideally, the shape of the hoof will echo that of the coronary band

A flare describes an outward distortion of the hoof wall due to imbalance. If part of the hoof is left longer than the rest,  that longer hoof will yield and pry away from the sole creating a flare. WLD will soon occupy the cavity between the wall and sole. Flares can be blamed on  too long of interval between shoeing/trimming or can be error on the farrier’s part (although some horses have conformation that makes this more complicated).  In either case, When the hoof maintained by a competent farrier and a diligent owner, flaring will be minimized. The emerging, unbent horn will be much stronger and not prone to WLD invasion.

Excess hoof length leads to flares. photo:

2. Loose shoes

Loose shoes cause  hoof damage, creating ideal conditions for WLD. The constant movement of the nails  erodes the adjacent  hoof wall.   Signs of loose shoes are raised clinches well before the next appointment, hoof wall loss below the nail line, shoe loss, and a ragged appearance.

Loose shoes damage the hoof, perpetuating WLD invasion.

Going too long between farrier visits and wet environments cause loose shoes. Shorting the  shoeing interval by a week, especially during the warmer months, when fungal problems are worst, will help. Don’t keep horses in dirty stalls or mud-lots and pick out hooves regularly.

As with flares, this can also be a result of inattention on the farrier’s part. A slightly unlevel or misshapen shoe can become loose prematurely.

Hot shoeing is a WMD for WLD.  A hot fit, clipped shoe, custom fit and burned lightly to the hoof will remain snug throughout the shoeing cycle.  The searing of the foot also kills any nearby microbes while sealing the hoof against moisture. For more on  hot shoeing check out my post “Hot Shoeing versus Cold Shoeing“.

Hot shoeing is a WMD against WLD!


3. Old abscess or hoof wall injury

Cavities created by past abscessing or hoof wall injury host WLD. Many horses have a small degree of this, especially in the center of the toe. This sort of cracking is so prevalent and consistent in location, it  may associated with the mid-dorsal notch of the coffin bone.  An inherent weakness combined with excessive toe length  would explain why horses with no history of abscessing often have these cracks.

Another source of hoof cracks caused by WLD is past  injury to the coronary band. Trauma to the coronary band can cause scarring. Hoof wall grown under the blemish can be malformed. This horn is very susceptible to WLD.

Injury to coronary band leaves area producing malformed horn that is susceptible to WLD

Expose WLD to air

Once the underlying hoof balance is identified and addressed, the current infestation of WLD must be debrided as much as possible. This may be achieved  in one session like in the top picture, or an ongoing process depending on the extent of the damage. Clearing of the muck filled crevices in the hoof is  necessary to rid the hoof of the microbes.

After the farrier work is done, make sure that you evaluate your horse’s home. Remedy wet conditions and make sure to keep scheduled farrier visits  so any new WLD can be dealt with promptly. The damaged hoof wall should be cleared daily with a wire brush to  expose it to air. After cleaning the foot I would recommend applying an antifungal to the area to discourage recurrence.

Shoeing Options for Club Foot in Horses

Shoeing options for the Club Foot in Horses

Do you have any recommendations on glue on horse shoes. My 15 year old Paint horse gelding was born with a club foot. He wears Cavallo simple boots, which are great, but was thinking about glue on horseshoes for him.

-Lauri R


club foot horses
Grazing stance allegedly plays a part in many club feet. Photo

Club foot is horseman’s term for contraction of the deep digital flexor tendon (DDFT). The foot will have a steeper angle and  smaller size than it’s mate. The most accepted causation  is that horses with long legs and/or short neck adopt a grazing stance where one leg is constantly stretched while the other is not.  Because grazing is a lifelong, primary activity, the unfavored limb can develop  functionally different from than the other. DDFT contracture can also be acquired, resulting from hoof trauma while a young horse is still developing.

No matter the why, the abnormal hoof growth seen in club feet is nature’s way of allowing the shorter (or less flexible?) limb to compensate for this disparity by developing a more upright conformation in the affected limb. The good news is that the majority of horses with a club foot can be shod with modified but regular shoes or kept barefoot with the help of an experienced farrier.

Contracture of the Deep Digital Flexor Tendon

In order to effectively shoe or trim a horse with this contracture one must understand why the tendon contracture would have anything to do with the hoof in the first place.

 The DDFT originates in the forearm, travels down the back of the leg and attaches to the underside of the coffin bone. When the horse engages the deep flexor muscle, the DDFT  lifts the heels off the ground.

Shoeing and Trimming Low Grade (a.k.a. Subclinical) Club Foot in Horses


The farrier must be conservative and mindful of the desired result when trimming this sort of hoof. Over-trimming the heels will cause more strain on the DDFT, possibly even suspending the heels above the ground! Although gentle stretching may have benefits, too much strain on the tendon will make the sore and susceptible to further DDFT problems.   Under-trimming the heels will leave the hoof overly steep, misaligned and prone to concussion related lamenesses . Excessive toe length will flare and attract White Line Disease as well as strain the DDFT. There must be equilibrium.

As mentioned, a skilled farrier can keep this hoof in that “just right” position. If this sweet spot is found, maining it by keeping the horse trimmed and/or shod on a 4-5 week rotation may be all that is needed to keep a horse with a low grade club foot sound.  I use four point trimming methods and will forge a broad-toe shoe to protect the sole and ease breakover for these slightly abnormal hooves.

Adding a bit of length via a pad on the club foot only may help some horses. This extra material shims the small hoof slightly.  Pads can be added or subtracted at the next shoeing depending on the results.

Options for More Severe Contracture

Corrective horseshoes for DDFT contracture will incorporate an elevated heel, a toe that is beveled to ease breakover and some kind of frog support .  Also, the web of the shoe is wider in order to protect the tip of the downward pointing coffin bone.

A farrier can custom make a shoe from scratch or fabricate a package that  combines a premade shoe with solid, pour in, impression material pads to elevate the heels and support the frog.

Nanric and Grand Circuit both make a wide variety shoes specifically for tendon contracture.  These shoes are also used in laminitis as that is a disorder of the DDFT as well. These shoes are designed by leaders in the industry and made from aluminum and  incorporate the elevated heel and eased breakover. The lightweight, one piece design make these shoes the best choice for nail-less shoeing. Check out these links as the huge array of shoes  available.

A farrier may also “rock ‘n roll”, “banana” or “add mechanics” to the shoe as well. This means the shoe will have a convex profile to the bottom to further reduce strain on the DDFT. This is an advanced technique.

Management of the club foot in horses primarily depends on keeping  the the hoof aligned with the DDFT. Regular and corrective shoes as well as barefoot trimming can all benefit a horse with this type of conformation. The decision on which route to go will depend on the severity. Radiographs are very helpful.

White Line Disease: Progression and Identification

White Line Disease: Progression and Identification

White line disease  describes the result of an establishment of hoof eating micro-organisms within  the  hoof wall, usually concurrent with another hoof defect, imbalance or injury where the microbes gain entry. WLD feeds on the intertubular horn which fill the tiny voids between the strands of horn tubules. Affected areas begin as areas of wall/sole seperation. Untreated, these voids fill with the digested hoof material, manure and other debris combine creating ideal conditions for the proliferation of the microbes and more hoof loss

White Line
Seedy toe or WLD associated with laminitis. The damaged wall is removed and the remaining horn disinfected. This foot will need shoeing. Note the new, tighter growth emerging.

This article attempts help horse caretakers understand and identify white line disease in horses.

Tubular and Intertubular Horn

The hoof wall is composed of countless whisker-like horn tubules. These horn tubules are constantly produced at the coronary band by the horn papillae. Horn tubules provide  structure, shape and resistance to vertical compression of the horse above. Intertubular horn is  also constantly emerging from the coronary band, but from in the spaces between the horn papillae. Intertubular horn fills the gaps between all of the individual strands of horn providing cohesive stability, resistance to wear, and mass to the hoof wall. Both components are made the same keratinized horn material, but this matrix gives the hoof great strength while remaining flexible.

How White Line Disease Affects the Hoof

Many horses have a small degree of WLD , especially horses in wet environments. Any defect to the hoof wall not open to air flow such as nail holes or old abscess tracts will be prone to WLD invasion.

minor case of White Line Disease, this one may be from a resolved submural abscess

Grass Cracks

Grass cracks, named for the dewy fields that can lead to chronically overly wet hooves,  describe numerous, small, superficial splits  caused by the erosion of the binding intertubular horn beneath the surface of the wall from white line disease.  Like grass, they start from the bottom and progress upwards.  The loss of intertubular horn is what causes this delamination of the hoof wall and the weakened areas to fray and split.

Grass Cracks. photo:
Delamination appears as loose, shelly wall is caused by WLD
Delamination,  breakdown of the hoof wall in layers, appears as loose, shelly wall.

Premature Loose Shoes and Clinches Due to WLD

Horseshoe nails, especially loose or ill-fitting can exacerbate WLD. When the wall looses it’s intertubular horn, it loses stability. The damaged wall near the shoe is the most damaged and will not resist vertical compression.  Instead of growing down, it  will flare out to the side. This causes the clinches to loosen. Loose nails move with each step, enlarging the nail holes,  leaving even more weakened hoof for WLD to homestead. Clipped shoes that are not hot fit will also cause this sort of damage because WLD will invade the tiny crack between hoof wall and clip.

WLD worsened by ill fitting clip, long toe and loose nails. photo:
loose clinches, overgrowth, bad clip fit=WLD photo:

Toe Cracks

A toe crack will originate from the center of the toe where the WLD first gains entry. The weakness can be from an old abscess, laminitis, clubby foot, excessive length of toe or from an inherent weakness in some hooves associated  with the mid-dorsal notch of the coffin bone.

The mid dorsal notch of the coffin bone may be a weak spot in the hoof wall. Photo:

White line disease is a very common condition in horses, especially those that already have compromised hooves. Horses with WLD are easy to spot due to the predictable progression of these hoof-hungry microbes.  Fortunately, most cases can be improved with best farrier practices, more frequent trimming/shoeing and environmental changes. I hope to share my thoughts and methods for the management of white line disease  in an upcoming article, so please like, subscribe for updates.

Hoof abscesses: symptoms and causes

Most Hoof abscesses are pretty simple to treat at home, I recommend this method after consulting with your veterinarian. Other than losing training time and a small fortune in elasticon, your horse will recover, the damaged hoof will grow out, and only the memory will remain.

Unless it doesn’t. This article , although absolutely no substitute for veterinary consultation, will go over the causes of your garden variety, inconvenient “gravel” abscess, as well why some horses seem to always be either having or recovering from abscess related lameness.

horse hoof abscess
Fix my paw!


Symptoms of a hoof abscess

  • the horse may go from normal or slightly off to a grade 3-5 lameness rapidly and unexpectedly in one limb. An affected forelimb will be more obvious.
  • the horse may aggressively manipulate it’s stance and gait to avoid weight-bearing on affected foot.  This horse is so lame, your significant other could diagnose.
  • Swelling or sensitivity of the coronary band, pastern or fetlock.
  • a bounding digital pulse can be felt on one or both branches of the arteries that run down each side of the back of the pastern of the lame leg  (medial versus lateral pulse can help pinpoint location of the infection).
    location for observing digital pulse

    Not always true, but abscesses often occur after paying nonrefundable horse show fees but prior to events such as a motivated buyer coming to see your prospect, trail ride vacation, graded stakes races etc..

Causes of abscesses

“An accumulation of purulent exudate. In the foot, this usually refers to a localised accumulation of exudate between the germinal and keratinised layers of the epithelium, most commonly subsolar or submural.”

Equine Veterinary Education, Vol. 19, June 2007

The above excerpt is a great definition of a hoof abscess, more simply, an abscess is (usually) a pus trapped between the insensitive and sensitive tissues.

The author then goes on to divide the abscess by it’s location: either between the sensitive and insensitive sole (subsolar) on the underside of the foot or trapped behind the hoof wall (submural) .

the “gravel” abscess

This is, by far, is the most common cause of abscessing in my experience, especially if the horse is barefoot.

The “gravel” type of abscess is caused by a small piece of debris getting jammed into a weakened spot in the white line or seat of corn area of the hoof.palmar-foot-drawing-labeled

Click to enlarge or check out structures of the hoof post.

Horses affected with white line disease , a common, fungal invasion of the insensitive horn.  are even more prone to the gravel type of abscess.

If debris manages to penetrate beyond the protective and insensitive hoof wall, bacterial invasion  into the  soft, sensitive tissue (corium) inside the hoof will follow.

Once the body barrier of hoof is penetrated, the abscessing process begins. The horse’s immune systems goes on the offence to prevent further damage from the foreign body: inflammation sets in, a thin, new layer of horn is produced to wall off the debris. White blood cells flock to the site. to fight off the bacteria. Enzymes released by this liquefies the now necrotic tissues involves, which produces the dark grey exudate associated with this condition.This  pocket of serum trapped against a minimally elastic hoof wall and the sensitive tissues within the hoof capsule. This combination is very painful for the horse.

Bad or close nails

Bad/ “Hot” nails

A misplaced nail can be the cause of an abscess. The nail is driven inside the white line and penetrates the soft tissue within the hoof capsule. You will know this because the horse reacts suddenly. He may not set his foot down, instead shaking it inches above the ground. Blood will seep from the clinch or nail head.

Hopefully farriers will circumvent the abscess cycle at this point. They will remove the nail, pour some antiseptic into the offending  and resulting hole, and most will inform the owner so they will be especially observant of that foot.and ensure the horse is up to date on his tetanus vaccination.

By removing the offending object and disinfecting, it is likely that the horse will suffer no more from this incident.

Close nails

A close nail is a nail that is driven into insensitive horn, but displaces hoof material in a way that affects the functioning of the hoof. There is no blood as the sensitive tissue hasn’t been breached. The horse may react to the nail being driven, but not the “kicked in the gut” reaction of the bad nail.

The close nail impedes the function and circulation of the adjacent sensitive foot. This may not become obvious for up to two weeks after the nail was driven. At this point the abscess will run its course as described for the gravel.

It is a good idea to remove the shoe and treat the hoof to speed  recovery and ease pain.

Horses with thin walls, previous hoof damage, clubby or low heels , and wry hoof are more likely to have close nails than a strong footed individual.

hoof abscess
Upright “wry” type of hoof. This hoof is badly twisted due to extreme varus or toed-in conformation in his pastern joint.

Horses that do not stand patiently are also more likely to have a close nail as the farrier cannot distinguish the horse dancing around the aisleway from pain or lack of manners.

Driving nails into a horse’s foot takes years and years to become skilled at. There is a very small area where nails can safely be places and no two feet are quite the same. The last thing a good shoer wants to do is hurt your animal, but it will happen occasionally.

not much room for error. photo:

A good shoer will take responsibility and be glad that this injury is fairly easy to treat.

Abscessing from the inside

Horses with diseases or injuries to the hoof sometimes suffer from abscessing without any external cause.  Horses that do not receive regular hoof care and horses with known hoof problems will  often suffer from chronic abscessing because there is a ongoing internal abnormality.

This is not meant to be a thorough guide to all hoof infections and horses with problems like these should be seen by an equine veterinarian for best results.

Chronic laminitis and pedal osteitis

Horses with a history of laminitis/founder are an excellent example of abscessing due to septic pedal osteitis (coffin bone infection).  The coffin bone of the laminitic horse gets progressively more damaged with each episode. These abscess can be submural or subsolar depending on which portion of the bone is affected.

coffin bone normal and one with changes due to pedal osteitis photo

Seedy Toe

Seedy toe
chronic laminitis and a nasty fungal invasion causes a condition commonly called Seedy Toe. This foot requires a high level of management between farrier, owner and vet.

Horses with chronic laminitis are also likely to have chronic submural abscessing in the toe. This is a result of malformed, scarred and or damaged horn that is a result of  laminitic cycle is prone infection.


The coffin bone may fracture. A fragment of bone that is broken away is called a sequester. The sequester can result septic pedal osteitis, lameness and abscessing. The offending segment may require veterinary intervention to end chronic abscessing.

Horses with coffin bones that have be damaged from trauma can abscess if the injury leads to infection.

Horses with thin soles and/or  worked on hard surfaces can also  develop pedal osteitis. Horses with coffin bones weakened by any disease  are also predisposed to  this internal abscessing.

Acute Laminitis

Horses in the acute stage of laminitis can suffer from abscessing from the extreme internal injuries taking place within the hoof capsule.

Acute laminitis with subsolar abscess caused by pressure from rotated coffin bone
Acute laminitis with subsolar abscess caused by pressure from rotated coffin bone

If a horse presents this type of abscess you are in need of qualified professionals with experience dealing with laminitis.

If a “professional” attempts to pare away at the solar surface of this horse to “dig out” the “infection” please reconsider this person’s expertise in dealing with hooves in general. This practice generally not recommended. The soft tissue will almost always prolapse through the sole causing further insult to an already bad situation.

Again, under no circumstances should an opening be created in the adjacent sole. This seldom leads to the abscess, generally leads to hemorrhage and may create a persistent, non-healing wound with increased potential for bone infection.”

Dr. Stephen O’Grady “Managing Hoof Abscesses”


A keratoma is tumor made of a horn (hoof material) that develops between the coffin bone and the hoof wall. Keratomas are not common, usually benign and a skilled horse person may be able to identify an affected hoof as the growth causes distortions in the hoof wall and white line.

Removal of a keretoma. Note the distorted coronary band that would alert a wise horse person to the abnormality. Photo:

Occasionally, pressure from the growth can cause  necrosis of the adjacent portions of the coffin bone  leading to Osteomyelitis abscessing. These keratomas may need to be removed under veterinary supervision to end the cycle of chronic osteomyelitic abscessing.

For more on keratoma read Dr. O’Grady’s case study.


A horse with an abscess is a common occurrence if one keeps horses for any length of time.  Luckily, most are treated, recovered from and back to work in under two weeks.

Horses that have chronic abscessing may be helped if the causation of the infection is identified. More aggressive treatment may be necessary for horses with certain types of abscesses.

How to Treat Hoof Abscesses in Horses

 How to treat  Hoof Abscess in Horses

how to treat hoof absesses

When asked how  to  treat hoof abscess, I recommend using an Animalintex  hoof pack to draw the infection from the hoof capsule. Abscesses will usually resolve themselves given enough time, however, it is far better to be proactive because:

  • The hoof abscess will usually resolve quickly if the abscess is poulticed and drained.
  • The poulticed abscess is more likely to be drawn out through the ground bearing surface. If left to resolve itself, an abscess will generally blow out the coronary band. An abscess venting through the top of the coronary band damages the entire hoof.

    treating hoof abscess
    old abscess tracts allowed to vent at the coronary band leaves the hoof badly damaged. It will take many months for this to grow out and leave a void for hoof eating microorganisms to thrive.

Animalintex packs are the most convenient way to draw the pus to the surface to using an isotonic solution. It is preferable to the traditional “hoof soaks”  which call for repeated, lengthy immersions  of the whole foot because:

  • multiple hoof soakings  water logs the foot. This will  compromise the already weakened foot. Using a warm, damp poultice is a better alternative than repeated, lengthy soaks.
  • The pack can be left on for 24 hours at a time.
  • Getting a horse to stand in a soak is difficult unless you have a special boot.
  • If the abscess does drain, it will be evident if the spent hoof pack is inspected.

Animalintex is at my local Tractor Supply Company for under $15. You will also need:

  • Vet wrap or elasticon
  • Duct or Gorilla tape
  • wire brush

If  Animalintex is not available, one part epsom salt and two parts wheat bran moistened with warm water and using a diaper as a vessel is a time tested alternative.

I do not think that ichthammol is a good medication for hoof abscesses at all. It contains formaldehyde which hardens the hoof wall, making it more likely the abscess  will vent through the skin at the coronary band. Again, it is much more desirable to get the abscess to vent through the bottom of the hoof. Also,  it’s tarry texture and strong smell will make it impossible to tell if you have drawn the abscess out.

10. Put a call in to your veterinarian, let them know you have a horse with a possible abscess.

Some vets and farriers like to cut a big hole in the hoof searching out the abscess. I do not care for this practice as

  • More often than not, they do not find the abscess because it is still too deep in the hoof. It is better to continue to poultice until the pus is drawn just below the surface.
  • Now the horse has a foot wound in addition to the abscess. This horse now requires weeks of stall rest and bandaging as his delicate sensitive hoof and possibly bone are now exposed to the environment.
This hole will take a long time to heal.

An experienced hoof person can look and palpate the hoof and have a pretty good idea of where the “track” is. The track is the spot in the hoof where the original breach of the hoof capsule occurred and an excellent place to drain it.  It is best to wait until only the slightest nick allows the pus to be expressed. I prefer allowing more time and poulticing to invading the hoof capsule in search of an abscess. It is usually not necessary to whittle the hoof until it bleeds.

Once the abscess is vented and drained , the horse will become noticeably less miserable and will continue to become more comfortable. I recommend flushing the tract with hydrogen peroxide and iodine.  There may be some residual foot soreness because the hoof has been traumatized. This should steadily improve until the previous level of soundness is achieved

When the horse is non reactive to reasonable palpation of the affected area, the shoe may be reapplied and the horse may be gradually returned to work.

Horse hoof care, fact and fiction

As a kid riding lesson horses first and then grooming and exercising privately owned horses for lesson money.  I got pretty far without knowing much about horse hoof care other than to always pick the  hooves before and after riding.There were a lot of boring hoof products my horsey catalogs that I didn’t understand. I  figured some horses had good feet, some horses had Navicular disease.

I did like those bell boots with the interchangeable colors a lot. Maybe dramatic foreshadowing?? Farriers love bell boots.

Farrier science takes years of study and thousands of feet in your lap to really wrap your head around how they respond to trimming, shoeing, time, the environment, management, use, etc..

The hoof  is so perfect, it seems simple at first glance. It is anything but.

This simple appearance is a source of many misconceptions. What seems like the obvious answer to an otherwise seasoned horse person, or sometimes fellow shoer, is not actually correct once the true complexity of the hoof is considered.

Here are a few examples:

1.  Some horses just have good feet.

hoof care
rock crushing appy feet

There are horses born with good feet, however, usually have some other things in common other than the prized, high quality hoof wall. Often good feet reflect of other nice things about the animal or where he lives.

  • Horses with legs that are mostly straight with hooves pointing in the same general direction will wear their feet evenly and be free of distortions like dished toes and flares
  • Horses with  cupped hooves
  • Horses that are in dry environments
  • Being related to other horses with good feet, intended or otherwise

There are also animals with not so great feet. This is not necessarily because they have actual “bad hooves”, it can be a result of one or a combination of factors.

  • Horses with conformation that causes them to paddle, rope walk, drag a toe, stab, be lame, etc will wear unevenly.  Without the regular intervention of a conscientious farrier one side will get wore to a nub while the other side grows long and flares outward.hip number 666
  • Horseshoeing or trimming by an unqualified or careless farrier can cause problems, especially if the same mistake is repeatedly made.
  • Hoof left not level or not trimmed often enough. The hoof will flare on longer.
  • Shoe doesn’t fit foot or left on too long. This causes corns or bruising of heels.
  • Shoe doesn’t fit, or left on too long. The nails waller out hoof wall of an loose shoe. Excessive nails.
  • Excessively wet environments are very detrimental to hoof quality.
  • Repeated shoe loss
  • Horses with sloping pasterns and low heel angle conformation
  • Nails behind the widest point of the foot restrict hoof function. This can lead to or exacerbate chronic hoof problems.

Horses that I would classify as having truly “bad feet” may have issues such as club foot, chronic laminitis, horses with “no heel”, and or moderate to severe white line disease. Feet like this have weaker or distorted hoof due to pathologies in the hoof capsule. This will require more frequent visits from a farrier with experience in managing imbalances and  management of their environment.

Seedy toe
chronic laminitis and a nasty fungal invasion causes a condition commonly called seedy toe or white line disease. This foot requires a high level of management between farrier, owner and vet.

Fortunately, even horses with compromised and diseased hooves can improve when hoof care is a priority.

My best advice is to be proactive and get your horses feet done before they look overdue and evaluate management practices in regard to the daily care and conditions. A step such as waiting until the dew has dried from a grassy field to turn out a horse would be a good example of this.

If your horse has distressed looking feet that are not improving and you are not getting a satisfactory answer of why, just like in other aspects in life,  it may be time to try a different approach.

2. Feeding supplements will cure my horse’s feet.

I do not recommend hoof supplements until all other balance, management and environmental issues have been resolved. Horses with bad feet have normal levels of biotin in their blood. Despite what you may have heard, there is  little evidence that supports that they have a significant impact on hoof growth or quality. These products cost well over $1 per day and there are valid, industry-wide concerns about the lack of regulation in the supplement industry. There have been recent allegations by scientists claiming these products do  containing any evidence of containing what the label promises.

Biotin can't cure hoof imbalances
Biotin can’t cure hoof imbalances

Biotin is he main ingredient touted by the supplement makers to promote hoof growth and it is required for not only hoof growth. It is required by every cell in the body. What no one ever mentions is that biotin deficiency is extremely rare. It is found in oats, hay and grass which is what most horses eat anyway. If you are feeding quality horse food, you should be fine.

Also, because hoof grows so slowly, it will take more than a year’s worth of supplementation to see the purported “results” that the supplement makers promise. I would like to suggest that it is more likely that improvements in the horses environment, management and farrier work is what leads to better looking hooves.

It is possible that since there are products that are touting other ingredients not as present as biotin in the equine diet. This may be of real benefit to some horses, I am not a nutritionist. People seem to really like to feed the hoof supplements for the right reasons. They want to avoid or remedy a nasty hoof problem, and of course I do too. I don’t think it is possible to “supplement” your way out of the majority of the hoof problems I come across.

The efforts and resources need to go into good shoeing and management first.

3. Judging the quality of a shoeing job by how long the shoes stay on.

No one likes a lost shoe, but losing shoes is a part of shoeing horses well. The best way to never have to go back and replace lost shoes is to use a shoe that is too small for the foot.

I was reading an olden time farrier book that has all horses on a 3-4 week cycle and going any longer was asking for trouble. Those people needed those animals so they did what it took, that may be the case with some today.

A properly fit horseshoe is going to be slightly larger than the horse’s hoof, especially in the heel area. The hoof repeatedly expands as it strikes the ground, supporting the horse and rider then contracts as the hoof is picked up. The shoe must be fit to accommodate both phases.

proper heel fit
the heels should be fitted slightly wider than the hoof from the mid line back towards the heels. This is to accommodate and protect  for expansion of the back half of the foot under full load


Although this extra lip of shoe is needed to avoid heel pain, it is more likely to get pulled than one that is too small. Fortunately, an expertly applied shoe should come off without damaging the wall.

 Using a hoof gauge to determine toe and heel length

A hoof gauge is a protractor for the hoof that measures the toe angle in relation to. Mathematically, the correct answer would be “not enough information”. No two horses are alike it is not possible to determine optimal balance without first addressing the animal.

I have worked for many nationally respected farriers and have attended many continuing education clinics and none  give any credence to this measurement that seems so important to some people.

Toe angle is important in the way the hoof relates to the limb and the horse’s conformation, not the ground, which is what the gauge is measuring.

The hoof angle should match the angle of the pastern. The length of the pastern will dictate the hoof angle and no farrier can change the conformation of your horse, nor is it a  good idea to try.

5. Don’t touch the heel!

The heel should be brought back  to the widest point of the frog. Attempting to make the toe steeper by leaving the heel sounds like a good idea, but since the hoof grows forward and down, this practice is detrimental to the health and proper functioning of the foot.

heels don't grow down, instead they migrate forward causing stresses in the back half of the foot. hoof care
heels don’t grow down, instead they migrate forward. This loads the foot  inappropriately, causing heel trauma.


hoof care long heels move the base of support towards the toe. Normally the weight is born on the cushy back half of the foot. With the heels left long the bony structures are taking the majority of the load. This can lead to navicular syndrome.

6. Using topical products to “fix” imbalance issues.

There are many premade hoof dressings on the the market and many more old-timey recipes that people claim will heal hoof cracks, grow hoof fast and cure what ails your horses troubled soles.

Hoof dressings can enhance the water repellency of hooves in some environments. It may help with some fungal/bacterial invasions as the ingredients usually contain some kind disinfectant like pine tar.*

Topical dressings do not grow new hoof or do anything to heal the sensitive structures within the hoof capsule no matter what they claim.**The hoof is dead, it is not possible for it to heal, it only possible to create conditions where it will be eventually replaced with undamaged horn.

*Horses with cracks in their hooves are very common in the Southeast that is related to year round wet/dry conditions that is hard on all of us. It is usually a white line disease related problem and needs a farrier with experience to debride affected horn. I do recommend antifungal topicals to fight fungal and bacterial invasions of the hoof wall.

**I do think hoof poultices are helpful to help with inflammation and isotonic soaks/packs to draw infections from the hoof,  See this for more.

10 ways to make your farrier visits easier

It takes a “special” type of person to sign on for twenty or so years of avoiding poop, drool, kicks, and sometimes bites courtesy of very large beast .  Add in the desire to hammer hot metal, hold thousands of nails in ones mouth and having hands that seem to permanently smell of thrush.

In addition to the physical demand of the craft, this person shall also have a complete working knowledge of  equine anatomy and locomotion as well as being an entrepreneur,  teacher and salesperson.

Sometimes with all of this knowledge and experience comes the tendency to become annoyed when non-farriers are not aware of things that can make our job harder, more dangerous or our work less effective.

it takes a “special” type of person to commit to the farrier life

There are some things you can do to becoming a favorite on your hoof care professional’s calendar.  Here is a list of farrier visit suggestions I believe the horse-owner can do to make the experience better for everyone involved.

1. Do your homework. There is no prerequisite to buy one of these animals and the instruction manual is sold separately. If you are new to the sport  seek some sort of guidance. Horse are big and can become very headstrong and if they think they have the upper hoof in the situation.

if you are new to the sport, seek a more experienced partner. photo b. cagle

I highly recommend taking some lessons at your local stable before acquiring a horse. A little supervised instruction will save you a lot of headaches and money down the road. If you can’t do that, buy or borrow a more experienced and older horse to learn on. You will enjoy horse ownership much more with a reliable and steady partner.

2. Provide me with a level, dry work area free of  clutter. If the horse decides to have a come-apart I want to be able to get away from him without tripping over your hay string collection. Also, it is dangerous to work in the field where other horses are loose.

Keep animals at bay as they are all very curious, Dogs like get underfoot, sometimes literally, trying to nab hoof trimmings.

3. In the summer it is too hot to work in direct sunlight. Let’s try to set up under a tree if there is not a barn to work in.

4. In the winter having some shelter is great, however, I work for plenty of people without a barn happily. Those people have a well drained sunny place and maybe a building acting as a wind break. I’m  happy to reschedule if the weather is truly awful.

5.If I am shoeing your horse, being close to my truck would be appreciated. I will have to make a lot of trips back and forth when fabricating and fitting the shoes.

6. Train your horse to be able to stand patiently. If your horse is  shying away from me and defecating constantly it is usually because he’s nervous.  Most likely he just needs more good experiences being handled.  Work with your horse from the ground regularly and watch him transform into a more confident and  agreeable companion.

Tie him regularly and he will become accustomed to being confined and messed with. If the only time this horse is handled is for farrier and vet work it is understandable that he would be suspicious.

7. Make and keep appointments. Not all horses are going to be able to go the maximum 8 weeks between farrier visits and trying to save money or time will yield unsatisfactory results. The farrier must stay ahead of the hoof growth especially with distressed feet.

waaay too long between farrier visits


8. Have all the accessories. A minimum of working halter and lead rope with the animals in a nearby confined area ready to be caught. Bonus points for having your horse fly sprayed in the warm months. Super bonus for cleaning the horses feet out.

9. Follow follow up directions. Your horse has white line disease or thrush? Treat the hooves with the medication and they will be WAY more likely to improve. I get a warm, fuzzy feeling whenever I see purple stains as evidence of your campaign for hoof health, Thrush busted!

10. For the love of all that is good, pick your horses feet out as part of your pre-ride or grooming routine. Horses are not naturals at standing on three legs. At all. The more you handle your horses legs the more skill he will have at balancing his thousand pound frame over a triangle instead of square.

Doing so on a regular basis helps me so much. Most of the reason for  farrier anxiety in horses is based upon the fear of the unknown. Problems start when the horse  looses balance.  The animal gets nervous which  causes the farrier to also become nervous. This is a vicious cycle that can end in all sorts of tragedy! Don’t let it start by having your horse comfortable and bored by the whole procedure.

In conclusion, I would like to add that I strive for progress not perfection. The fact that you have read my little post about my preferences goes a long way. Us cantankerous, crumpled and stinky farriers thank you for your interest. In the end, I love being a part of team “your horse” and want to right by him, and sincerely appreciate your business.

See you in six weeks;).


Hot shoeing vs Cold shoeing

Hot Shoeing vs Cold Shoeing

I can remember being very nervous the first time I fit a hot shoe to a live horse.  The combination of hot metal,  sharp tools and live horses seemed risky, surely there was good reason. Why do some farriers hot shoe and others  opt out from all the smoke and flame?

hot shoeing vs cold shoeing

In my schooling,  apprenticeships and first years on my own I almost exclusively hot shod.  About five years in, I  became  involved with the thoroughbred racing and breeding industry.  For a variety of good reasons explained later, most race stock, especially, the sales yearlings, and horses in training and racing are shod cold.

I have shod horses well with and without the use of the forge.  One way isn’t inherently better for every situation, but having a choice lets me  bring more options to my clients.

The benefits of hot shoeing

1. Hot metal is more malleable

Heating the metal prior to trying to change its shape is like letting the butter defrost before serving it with rolls.  The metal is much easier to work with;  the bends and dimensions can be controlled with a much greater degree of precision when the steel is red hot.  If the horse needs a shoe with any sort of modification, ( ex. rocker toe) hot shoeing is in order.

The toe of this shoe has a rocker toe.It would be nearly impossible to get this common modification without the forge.

2. Create a perfectly level hoof

A perfectly level foot will hold a shoe much better than one that is almost level.  Imagine a table that isn’t exactly level, and the wobble just a fraction of an inch creates.  It’s the same thing with the shoe except you can’t fix it with a coaster.

If the foot or shoe isn’t level, it’s obvious, if you are hot shoeing.

I realized the heel of the shoe was slightly bent

3. The ability to “hot fit”

When I set the hot shoe onto the hoof, a.k.a. “hot fit,” about 1/8″ of horn is melted. This creates a perfect marriage of hoof and shoe.  The hot shoe has evened-out any variation in the hoof wall and creates a gasket like seal with the shoe.

4. Clips work best when “hot fit”

I like to use clips on most horses.  Nails are a necessary evil that damage the hoof wall, to some degree, no matter how skilled the farrier.  Clips help secure the shoe and help reduce the stress on the nails and the hoof.

Hot fitting, clipped shoes create a divot that locks the shoe in place.

The case for cold shoeing

Some shoes are not made to be heated up and doing so could be dangerous.  The shoes worn by the majority of thoroughbred racehorses become very brittle when heated, and could easily break under the weight of the horse.

2014 11 05_0250

Hot shoeing may not be practical.  Some clients may not want the fire risk involved with hot shoeing.   Having any kind of open flame in a barn setting requires safety precautions.  If a horse must be worked on in a stall or if the barn is littered with hay, I would rather not take the risk of introducing a flame or red-hot metal.

With cold shoeing, the farrier is more nimble and able to service horses without as much equipment.  A skilled farrier should be able to level and fit most shoes accurately, without the luxury of a mobile shop.

Lastly, some horses are “non-smokers.”  Some horses may come completely unglued by the sights, sounds and smells of hot-shoeing, even though, the process is painless.  The hoof is an excellent insulator.  Tests have shown that the heat used for hot-shoeing does not harm or involve live tissue, however, some horses still take issue with the process.

"you want to do what!?!"
“you want to do what!?!”

In conclusion,  there are as many ways to shoe a horse as there are farriers. I hope hot shoeing versus cold shoeing has answered some questions you haven’t had the opportunity to ask or given some insight of the possibilities of more advanced hoof care.   As long as attention as been paid to fit, form and function the end result will be a well-shod horse.

Horseshoe Selection: How to pick the right shoe for the job

Horseshoe Selection

I love being able to have choices when selecting the shoe for the horse in front of me. I carry different versions of each size of shoe in order to truly customize the job depending on the horse’s individual needs. How does a farrier or horse owner chose the most appropriate footwear for a particular horse? To have this discussion let’s talk about the terms farriers use when describing a shoe.

Size: The most obvious, big hooves = big shoes and vice versa.  Using too small of shoe is a sure way to rob a horse of years of productivity, one that is too big is more likely to get pulled off, possibly  damaging the hoof, and inconvenience everyone involved.

Big horse, Little horse horseshoe selection matters
Big horse, Little horse, horseshoe selection matters

Usually the small horseshoes are labeled “0” or “00” and pronounced “ought” or “double ought” in reverence of the old fashioned word for zero . I have seen as small as “four ought”. Shoes larger than “0” will be labeled 1,2,3….

Just like any shoe shopping experience, there is no universal system for shoe sizing. Not only is there huge variation in comparing different brands take on what a size one is, but there are completely different systems especially if you are using European shoes, racing or polo shoes.

Material Most commonly cast or machined from mild steel or aluminum. Steel is more durable, easily worked in the forge and less expensive. Aluminum shoes are much lighter, able to be applied with glue and available in many styles for therapeutic applications.

The market for shoes made of even less traditional materials like plastic, rubber and fiberglass or the combination of seems to be growing. I’m sure as 3D printing becomes more accessible, choices will continue to increase.

Web size  describes the dimensions of the metal used to make the shoe. Narrow webbed shoes will sink into the earth easier and give a better grip. Wider ones will float the foot over soft footing, provide a more rigid support, more protection and allow for more slide. A wide webbed also offers more surface area to distribute the horses weight which better mimics the barefoot horse.

This is a racing shoe for a thoroughbred. It is narrow-webbed to sink into the surface and fullered shoe for added grip.

Weight of shoe: the heavier shoe the higher the arc of stride, the lighter the lower.

Traction devices: the shoe can have modifications to limit the sliding of the hoof. A harder metal (tungsten carbide, tool steel, borium) can be attached to the shoe by brazing or welding that allows the animal to be used on pavement. Calks can be built into the shoe or holes can be drilled and tapped to accommodate screw in studs that can be changed by the rider to suit the going.

Plain  shoes give less traction than the barefoot so it is very common for those shoes to have a grove (farriers would called this a “fullered” shoe as the tool used to make the crease is called a fuller). in the ground bearing surface to break up the surface area to prevent the horse from slipping under normal circumstances. The fullering also allows   nails to be removed one at a time.

the grove holds dirt to prevent skidding as well as allowing removal individual nails.

Reining horses are often fit with plates that increase the slide phase of stride.

Kerrkart Sliding Plate
This is a sliding plate. Its wide web and lack off fullering keep the horse from sinking into the footing and maximizing the slide of the hoof.


It is imperative to understand the perils of over-using traction devices as it can negatively effect the shock absorbing mechanisms built into the horse’s limb, especially on young stock. The animals caretakers need to know which horses have special shoes as they can  injure themselves and others without proper precautions.

2014 11 05_0142

Therapeutic shoes: Heart, egg, and straight bar shoes are available off the rack. Shoes with enhanced breakover built into the toe as well as ones with elevation built into the heel can help horses with some types of injury or disease.

Those are the most common ways to classify horse shoes. I am sure that I missed some,  especially now as it seems that there are new brands coming out all of the time. I believe in keeping things simple and mostly shoe with a steel clipped medium-wide webbed shoe until there is a reason to use something else. When an exception comes along it is great to have all of these options to chose from.
