British Barefoot Hoof Tape Controversy Escalates: Advocate Pledges Legal Assault on Farriers Registration Act, Council, and Illegal Farriery Charges

It’s just part of the horse. A few cubic inches at the end of a leg. But who’s in charge of it, anyway?

In Great Britain, the furor surrounding sovereignty over the hoof just won’t go away. In other parts of the world, including the United States, it may seem like it’s much ado about nothing. But when decisions and news about the definition of a profession are made half a world away, it potentially makes a difference everywhere.

In September, the Hoof Blog reported on a court case in Great Britain in which a hoof trimmer pleaded guilty to illegal farriery because he applied what is commonly called “hoof casting tape” to a client’s lame horse.

Information for that article was provided in the form of a press release from the Farriers Registration Council, a statutory body in Great Britain with powers to inititiate legal processes against non-farriers; the agency is charged with enforcing the Farriers Registration Act, an Act of Parliament passed in 1975 which defines farriery for that nation and prohibits anyone but a registered farrier or veterinarian from shoeing a horse.

Read the previous Hoof Blog article about the barefoot trimmer's hoof tape prosecution.

How do you get to be a farrier in Great Britain? It's not easy. A four-year-and-two-months apprenticeship and examination are required; farrier education and training are the province of a separate body, the Worshipful Company of Farriers (WCF). Only "Approved Training Farriers" are allowed to have apprentices.

For a long time, the FRC’s dominion over the hoof was more or less unchallenged, except by the occasional unregistered farrier plying the trade on the sly. When barefoot trimming came along, the new professionals were tolerated outside the dominion of both the FRC and WCF because farriery's definition in the UK describes it as  ‘any work in connection with the preparation or treatment of the foot of a horse for the immediate reception of a shoe thereon, the fitting by nailing or otherwise of a shoe to the foot or the finishing off of such work to the foot’.

Hoof tape is a popular hoofcare product in the United States and is sold in different forms by different manufactures. The  British campaign does not specify particular brands or applications but rather cites the use of the product on hooves. (Hoof Blog archives graphic from first report on hoof tape prosecution)

No shoe? No problem. At least that is how the barefoot trimmers viewed the law. They were free to conduct business. In a move that most freethinking Americans would consider evidence of a nanny state, the British government agency LANTRA set up a government body to develop training and testing systems to manage the new trade.

But perhaps everything wasn’t spelled out as clearly as it needed to be. The professional standards for barefoot hoof trimming don't mention the use of shoes or the application of support materials.

Is hoof tape a shoe? The FRC seemed to think so, and in the recent court case, the legal judgment concurred. But the tempest in the British hoof tape teapot might be a bellwether for legal tests of farriery around the world.

The hoof trimmer pleaded guilty to illegal farriery and was charged a fine and court costs. But he wasn’t the first: Less than a month before, another hoof trimmer was charged for using hoof tape. Her charges were dropped.

Horse owner and hoof tape
advocate, Annette Mercer
But one of her clients doesn’t want to let it drop. A horse owner named Annette Mercer from Bath, England has established a legal defense fund for barefoot trimmers who run foul of the definition of farriery; she has published a manifesto to topple the power of the Farrier Registration Council and re-write the Farriers Registration Act.

Annette Mercer credits the work of her hoof trimmer and the effects of wearing hoof tape for the remarkable recovery of her horses from a variety of hoof-related complaints.

The website "Fighting for the Barefoot Horse" is Mercer's call to arms with three aims. Her web site tells us: (quoted from web site)

  • The immediate aim is to put a stop to the FRC (Farriers’ Registration Council)’s prosecution/persecution of barefoot/podiatry practitioners, such as Lindsay Cotterell and Tom Bowyer;
  • The medium term aim is for the community of barefoot owners and practitioners to take up the LANTRA challenge to put in place a nationally recognised program of training and qualifications for barefoot care.
  • And finally, we would like the current legislation that governs the definition of what is a shoe – The Farriers (Registration) (Amendment) Act 1977-- to be repealed and replaced with something that recognizes both our growing understanding of the miracle of horses’ hooves, and also the technological advances in products to support the barefoot horse. The flexible hoof wrap, featured in current FRC prosecutions, is just one example of such products.
"We don’t believe in telling anyone they must take their horses’ shoes off and allow them to go barefoot, although it’s clearly worked for us. But nor do we accept the right of the FRC, a trade body that represents the interests of farriers who shoe horses, to tell us that we can’t use a barefoot hoof care provider to care for our horses and to threaten us with prosecution if we do," Mercer writes on her new website.

Attorney Lawrie has pledged to
defend the next hoof trimmer
charged with illegal farriery.
(web site photo)
The “Fighting for the Barefoot Horse” campaign has pledged 15,000 British pounds (US $24,000 ) to defend the next trimmer who is accused of performing illegal farriery by applying hoof tape. The money is pledged to the research expenses of Ian Lawrie QC, described as a “top UK lawyer”, who has agreed to represent the barefoot faction on a pro bono basis, minus those research fees, apparently.

Mercer writes that the privileges of the Farriers Registration Act "prevent the progression of the barefoot movement in the UK and mean that owners like us are forced to employ farriers to look after our horses' hooves. It is a blatant case of bullying by the FRC; the big boys thinking that because they have money behind them they can abuse their statutory powers and push people into doing whatever they want."

In reality the FRC is not in business just to ruin a barefoot trimmer's day. The most recent case before the FRC’s Disciplinary Committee was to chastise one of its own. A farrier performed what sounds like excavation of an abscess in a horse's sole, but the horse became more lame. When the vet was finally called, the horse was diagnosed with quittor on its pastern, and the farrier was prosecuted for failing to recognize that condition, as well as failure to seek veterinary treatment of the lameness. Judgment will be forthcoming.

In another case, a farrier convicted in a court of law for drug possession had his professional status reviewed by the FRC. He was not "struck off the register"--banned from working as a farrier--but his judgment will also be announced at a later date.

It sounds like the British governing bodies need to define one of two things--or more: What's the definition of a barefoot horse? Or, what's the definition of a shoe? Must a barefoot horse be literally bare? Is alternative hoof support--whether removable or fixed--a shoe by another name?

In Germany, the situation was even worse, since farriery there was defined with the inclusion of applying steel shoes. Alternative farriers started businesses using plastic shoes, glue-on shoes and hoof boots, as well as barefoot hoofcare, and were not required to go through long apprenticeships the way that farriers did as long as they didn't use steel. An effort to reform farriery there failed to combine the two professions, after proposing that everyone learn to both shoe with steel and use alternate materials. The barefoot faction simply refused, saying that they should not be forced to learn a skill they wouldn't use.

Barefoot hoof trimming worldwide has evolved so that a percentage of horses are being "equipped" with alternative materials like hoof tape, or wearing hoof boots, which are removable hoof protection and could be technically argued to be a type of shoe in a courtroom context.

From far across the Atlantic, it looks like the British missed an opportunity to define barefoot trimming as an adjunct form of farriery so the trimmers would be protected by law instead of being victims of it.

The word "barefoot" may come back to haunt the new profession, just as the word "shoe" pigeon-holes the farriers. Unfortunately for horses and the advancement of hoof science, the British problem continues to divide people into camps and hold back progress, rather than carry hoofcare forward.

If you asked anyone from either camp, they would say that that is what they want: progress in understanding the foot and improving the care they can offer. But, the way things are set up, each camp wants it on their terms.

And if you ask anyone who's been there, decisions made in court rarely clear the air and usually benefit the lawyers involved more than the people on either side who will be affected by even the most well-intentioned efforts to interpret, reform or create a law.

British Pilots Abort Flight, Alert Firefighters When Burning Smell Noticed

The firefighting unit responded to pilots' notification of a burning smell in their aircraft at a British airport tonight. (Paul Hamilton photo)

A British flight was aborted earlier today when pilots returned to the terminal after they both said they identified a burning smell.

The pilot and co-pilot of a flight from the island of St Mary's in the Isles of Scilly to Newquay in Cornwall were alarmed, according to a report in the newspaper, This Is Cornwall.

Airport firefighter Kevin James said: "It was lined up ready to take off when one pilot said to the other 'can you smell burning?' to which the co-pilot apparently replied 'I was wondering whether you were going to say anything in case it was just me'."

Control tower personnel alerted the firefighting unit.

"We were told of a burning smell in the cabin," said Mr James. "While other flights were put on hold we dashed to the fire engine and put on our kit."I had a chat with the captain and disembarked all the passengers.

"One of the last to get off looked at the first officer and said, 'I think it might be me'."

Mr. James disclosed that the person who spoke up was a farrier from the mainland who had been shoeing horses on the island all day.

Sometimes farriers can't avoid taking their work with them at the end of the day.

Hallmarq Standing MRI: Hoof Conformation from the Inside Out

 
This sponsored blog post is the latest in a series produced in partnership with Hallmarq Veterinary Imaging. Thanks to Hallmarq for their support of The Hoof Blog. This video explains the process known as "Standing MRI" of the equine foot using a Hallmarq system. The units are in use around the world.

Which came first: the chicken or the egg? 
Forget everything you “know” or think you know, about the relationship between foot shape and lameness. What matters in this age of evidence-based veterinary medicine is 1) what can be demonstrated and measured; 2) reliably repeating what was demonstrated; and 3) documenting the data of the measures.

If some hoof research makes you yawn and seems to be proving what is already obvious to you, remember that building a better tower of knowledge means that we know we can count on the blocks at the bottom of the tower. They must be proven before we can move on.

Hoof science is shy a few blocks. The tower is still on the drawing board. In order to document what you "know"via the scientific process, it is necessary to approach it from different angles so that it can be measured.

The deep digital flexor tendon (DDFT) is the most common site of damage in the foot identified by standing MRI scanning of sport horses. As you know, this tendon runs down the leg and attaches to the bottom of the coffin bone (P3). The three arrows added to this scan are directing the eye to the portion of the DDFT which, in this Irish horse, has a lesion that looks like a split. Normally tendon would be solid black. The recent study in England looked at a group of horses with similar injuries of the DDFT and measured for similarities in the conformation of foot structures. (Photo courtesy of Troytown Equine Hospital, Co. Kildare, Ireland.)
When researchers at Great Britain’s Royal Veterinary College wanted to get to the bottom of this age-old conformation to lameness relativity issue, they used Hallmarq standing MRI images to collect data that could be measured. The group of investigators worked under the direction of Renate Weller Dr Med.Vet, PhD, MRCVS, FHEA, senior lecturer in diagnostic imaging and locomotor biomechanics, at the RVC's Structure and Motion Laboratory.

Tim Mair, BVSc, PhD, DEIM, DESTS, DipECEIM, MRVCS is an author of the paper and a partner in England's Bell Equine Veterinary Clinic, where Hallmarq Standing MRI scans were sourced by Hallmarq's Nick Bolas. Also from the private sector, and a recent RVC graduate, Jonathon Dixon BVetMed MRCVS of Rainbow Equine Clinic was involved with the study.

The premise of the study is an inside-out refinement of hoof confomration. Instead of measuring the circumference of the hoof capsule and the contour of the coronet, they measured or calculated characteristics of the structures inside the foot. The availability of real-world lameness cases' standing MRI scans meant that the researchers had the luxury of a library of almost 200 images of injured or lame feet that met the study's criteria.

The MRI would have been originally made to assist in a definitive diagnosis on a lame horse. The clinician noted that the MRI showed a lesion in the deep digital flexor tendon or injury to the navicular bone, etc.

The researchers from the Royal Veterinary College undertook the project of evaluating these standing MRI scans not in the context of a single lame horse, but in the hopes that they would find other similarities in the feet of horses that had received the same diagnosis.

Once again: don’t assume anything, but see what the MRIs had to say.

If you overlaid a dozen images of the same type of injury from a dozen horses’ hooves, would the hoof capsules line up and show similar characteristics?

The researchers found that there indeed was similarity in the measurements of feet with the same diagnosed injuries.

What type of horses and lameness?

The mean age of horses in the study was between ten and eleven years; the average grade of lameness was approximately a “3” on a scale of 1 to 10. Breeds included 37 Warmbloods, 51 Thoroughbreds and Thoroughbred crosses, 22 Irish sport horses, 15 Irish draft horses and Irish draft crosses, 11 Cobs and 43 horses of other various breeds.

The horses had been diagnosed with many types of injuries, including lesions of their deep digital flexor tendon (DDFT), navicular bone (NB), collateral ligaments of the distal interphalangeal joints and
25 other structures.

What was measured? C, sole angle; D, toe angle; H, heel angle; N, deep digital flexor tendon angle; PL1, plumb line 1;  PL2, plumb line 2;  MA1, proximal moment arm; MA2, distal moment arm; SI, distal phalanx length; LC, toe length.

Sole angle


Sole angle is a relatively new term in the lexicon of foot anatomy. It is not the angle formed where the sole meets the wall, as documented in some studies. Its number is not describing the sole at all, in fact, rather the concavity of the coffin bone.

Dr. Weller took the time to explain it for Hoof Blog readers as the concave sole surface of the coffin bone to horizontal angle. Check the diagram to see the point on the mid-sagittal MRI scan where this angle is measured.

Dr Weller explained: "The issue we have in practice is that the sole angle we measure on radiographs does not correspond to the angle at which the DDFT actually attaches, but (rather we measure) the lateral and medial coffin bone borders.

"This (angle of the coffin bone) can be taken as an approximation at best, since the concavity of the coffin bone differs between horses. So some may have little concavity and in those horses the radiographic measurement will correspond quite well to the insertion angle of the DDFT, (however) some horses may have (a) very concave coffin bone and in these the radiographic measurements will not represent the DDFT insertion angle.

"The reason we care about this angle is that it is strongly related to the strain the DDFT experiences and hence the pressure this tendon exerts on the navicular bone," she concluded.

Measurement results

  • A larger sole angle was associated with combined deep digital flexor tendon (DDFT) and navicular bone (NB) lesions, but not with NB lesions alone.
  • A more acute angle of the DDFT around the NB was associated with DDFT and NB lesions.
  • A lower heel height index was linked with DDFT injury.
  • The larger the sole angle, the smaller the likelihood of a DDFT or NB lesion.
  • Measurements of the feet in the study contradicted findings of other studies.

Why is this study important?

Taking measurements from diagnostic images is not a new idea, so why is this study newsworthy? 
Previous studies have shown that certain conformational traits--sole angle in particular--increase forces acting on the DDFT and NB in sound horses. This study supports these findings by showing that conformational parameters are associated with DDFT and NB lesions in lame horses.

Standing MRI is done with the horse
bearing weight on the injured limb
The researchers noted that while this study shows an association between certain conformation parameters and foot lesions, foot conformation cannot be identified as causative factor of lameness. "Foot conformation may change as a consequence of lameness," they concluded.

Which brings us back to the chicken and the egg.

Future studies at the RVC will focus on dynamic conformation by investigating foot-surface interaction in lame versus sound horses, which may eventually open a preventative and/or therapeutic window for horses in the process of developing specific lesions within the foot.

Relevance of this study


The study's findings emphasize the deep digital flexor tendon's influence on the conformation of the foot and that it plays a leading role in many foot lameness problems. The DDFT's angle within the foot and the relative concavity of the distal phalanx (P3) (as measured by sole angle) may become routinely documented in the future.

Studies like this one are changing the way that foot structures are evaluated and measured. Standing MRI scanning provided three-dimensional evaluation of the foot, expanding the diagnostic field for the most precise possible examination of foot tissues and for the most accurate measurement protocols for scientific relevance. 

But Weller’s team’s emerging protocols for evidence-based hoof evaluation provide the sport horse and racing worlds with a basic building block that could one day be used on important studies to answer questions on equine welfare, prevent pain and increase a horse’s useful years. The hoof is one of the last frontiers of equine science, and the Royal Veterinary College is dedicated to learning more about it.

Research can’t be any more relevant than that.

Silent Anvil: John Collins Was Zenyatta's Hoof Man, Kentucky Horseman, Everyone's Friend

John Collins shod horses, played polo and enjoyed his friends. He died suddenly in Kentucky last week. (Scott Morrison photo)

I wrote about Kentucky horseshoer John Collins once. But I wasn't really writing about him. I was quoting what other people (and horses) had already written about him.

John Collins
Take, for instance, what Zenyatta wrote on her blog about her Bluegrass hoofsmith when she returned to Kentucky from her stellar racing career:

"My blacksmith here at Lane’s End is the same person who took care of my feet years ago when I lived in Kentucky! His name is Johnny Collins. He is the same man who put on my shoes when I went to the Keeneland Sale in September, 2005! He took care of my feet when I was a little girl!

"Now, here he is taking off my shoes at the farm several years later. This is absolutely adorable! Johnny told me he’d been keeping track of me and all of my progress since then! It was so great to touch base with him, my first blacksmith, after all of these years!"

I quoted what the New York Times had to say about John Collins, too, and shared their photo of him.

And after his sudden and premature death last week, I once again found myself reading what other people had to say about John Collins.

The wrong side of John Collins was featured in the New York Times the day John pulled off Zenyatta's race plates when she arrived back in Kentucky to become a broodmare. I guess the photographer didn't know that if he waited a few minutes, the horseshoer and horse would both face the same way. What I love about this photo: Zenyatta's near hind is off the ground. She's balancing on two legs. John's apprentice could have been pulling the hind shoe at the same time...(Credit: Luke Sharrett for The New York Times

I never met him. I always meant to. I figured I'd run into him in Kentucky some time and introduce myself, since I was sure he wouldn't have a clue that some writer in Boston had been writing about him all this time.

But I never got the chance. John Collins was only 50.

What I do know is that other people are still talking about John Collins, and I've pulled together a patchwork quote quilt to share with you:

John Collins learned horseshoeing as apprentice to the legendary Jackie Thompson who in turn learned the trade from George Tompkins. In my last conversations with Jackie before his death, he said he was worried about how to keep African Americans in the Bluegrass active in horseshoeing. (Hoofcare file photo)
Doug Watkins, Breeders Supply (horseshoe retailer in Lexington): "He loved horses, period. Loved working on 'em, bettin' on 'em and ridin' 'em."

Mike Cline, manager of Lane’s End Farm: “No one had more friends than Johnny Collins.”

Dr. Scott Morrison, Rood and Riddle Equine Hospital: "I knew him well, from polo and horseshoeing, we took a few trips together."

Don Robinson of Winter Quarter Farm in Lexington, where Zenyatta was foaled: "We are crushed."

Doug Watkins: "He was an avid polo player which is a bit unusual for a person of color. Bobby Bryant, who worked for John a while, commented on Friday that he played polo at Bruce Hundley's on a regular basis which probably would have been frowned upon except that everybody loved to see the women who came to watch him play."

Mike Cline: “He’s just one of those people you wanted to be around. I feel really bad for his mother, his sisters and his family. We are all in shock out here. He was a really fit, healthy guy.”

Scott Morrison: "I think everyone he met quickly considered him a friend. He loved horses, going to the races, playing polo and shoeing them. He was an ex-boxer and basketball player."

Johnny Collins (far side) and Scott Morrison at polo. (Scott Morrison photo)

Don Robinson: "John was like your friend and family. And he had a way with horses--he was a natural. He’s one of the few people I’ve seen that was just a natural with horses. He was absolutely at ease with a horse, and they felt it.”

Doug Watkins: "Every time he walked in this door he had a smile on his face and we would laugh and cut up with his apprentices, Nate and his nephew, Carl (Scoobie)."

John Greathouse of Glencrest Farm in Midway, KY: I'd like to think that John was not only our friend but a go-to guy at the sales and the farm. Will he be missed? More than anyone can know..."

The Paulick Report noted that John Collins was a graduate of what Robinson called the “Jackie Thompson finishing school,” a reference to the highly respected Central Kentucky farrier who, in turn, learned from the legendary George Tompkins. Though the three men, all of them African-American, were unrelated, their craft was passed down from one generation to the next almost as if they were family. Collins referred to Thompson as “Uncle Jack.”

Doug Watkins: "There were also many discussions about how to fix problems on foals and yearlings and stories about 'Uncle Jack'. Every visit (to the shop) was an adventure."

Don Robinson: "He was a class guy. I’m lucky to have known him.”

Scott Morrison: "He took on, and trained, many young farriers. He was the kindest guy I knew. He had a smooth friendly way about him, with people and horses."

Doug Watkins: "One of the last times I saw him he had forgotten his receipt and his truck was still in the parking lot so I took his ticket to him and Scoobie rolled down the passenger window. There they were eating Lee's fried chicken with Nate in the back seat and I said 'I see how you guys are,  white folks sit in the back, huh?' and we laughed and laughed over that one."

Scott Morrison: "He shod at Lane's End, Winter Quarter (where Zenyatta was foaled), Winter Green, Mill Ridge, Miacomet, Glencrest . He handled the feet of many great horses. He learned from Jackie Thompson (and) started shoeing when he was 16. He was 50 years old when he died."

John Greathouse: “The world lost a great person...You were as good a guy as there was out there and a good friend. I will miss our time together. My condolences go out to Johnny's family. I was glad to have known him and will miss him dearly. RIP Mr. Collins.”

Doug Watkins: "Don't get me wrong, he was a VERY good horseshoer but that fact is not what made him. He was fortunate enough to work on some very nice horses with some great people in his career and horses like Zenyatta are hard to screw up. What made John was the fact that he was such a good person.  I hope the way I put this doesn't take away from his abilities because it wasn't meant to. He was just such a good person."

Rest in peace, Mr. Collins. And anyone reading this: please pass this man's spirit on.

Equine Hoof Canker: Topical Chemotherapy Successful in European Trial

Hoof canker before treatment in the left front foot of one of the case horses in a study from the University of Vienna in Austria. Dr. Apprich documented her trial use of a chemotherapy drug in topical form to prevent recurrence of persistent canker. (© Veronika Apprich, used with permission)

Canker is the common name for what most horse owners describe as an “ugly, smelly growth” on the bottom of a horse’s foot. People describe it as looking like jellyfish, or cauliflower, and they always mention the foul odor that hits them when they lift the horse’s foot.

Canker in horses’ hooves is one of the most confounding problems in equine podiatry today. Most horse owners have never seen it, let alone smelled it. They know something is wrong, and treat it like thrush. While thrush progressively destroys the tissue of the frog, canker appears to grow out of the bottom of the foot. Treatment with thrush medication is futile.

If canker is left untreated, the horse becomes lame and the owner eventually calls the veterinarian, who may or may not have seen it before, either--but who can deduce what it probably is. Medication and topical treatments begin, but the problem may persist, and owners’ resources may not extend to surgical debridement or repeated procedures.

Many cases of canker end in frustration for owners and pain or even sometimes death for horses. Some recover, some do not. The ones who recover may do so only to experience a recurrence of the problem, causing many owners to give up.

What is canker?


Equine hoof canker (known in equine dermatitis texts as pododermatitis chronica verrucosa or chronic hypertrophic pododermatitis) begins in the caudal part of the cleft of the frog and gradually expands to the sole and wall. Equine canker is not lethal in and of itself, but because of where it occurs on the foot, and because it can be so difficult to treat and it recurs so often, it can severely compromise a horse’s soundness. The etiology of equine canker has been a topic of discussion for many years, but the specific cause is not known.


Canker and sarcoids


In many ways, canker is similar to equine sarcoids. Like canker, sarcoids also tend to be difficult to treat and often recur. Both canker and sarcoids often include a mixture of proliferative and erosive changes in the skin secondary to overgrowth and thickening of the tissues.

Due to these similarities, it has been speculated that bovine papillomavirus (BPV) might also be involved in causing canker.

Researchers have documented the existence of BPV in hoof canker in recent research, but it does not always show up in tests. A paper by Angelique Jongbloets et al at the University of Utrecht in 2005 documented a case of a horse with canker in all four feet that without any BPV present. That case was successfully treated as an autoimmune disorder with steroid medication, and successfully recovered.

Hoof canker before treatment in the right front foot of the same case horse shown above, in a study from the University of Vienna in Austria. This horse had canker in all four feet and was being treated for the condition for the fourth time when he entered the study. Thirteen months after the chemotherapy, he had a small recurrence in one foot; this was the only horse out of eight to have a recurrence. (© Veronika Apprich, used with permission)

Topical chemotherapy treatment trial



Last month, the British Equine Veterinary Association (BEVA) Congress in Great Britain included a clinical research abstract authored by Apprich and Licka from the Equine Clinic of the University of Veterinary Medicine in Vienna, Austria and Department of Veterinary Clinical Studies, The Roslin Institute, Royal (Dick) School of Veterinary Studies, University of Edinburgh, Scotland, respectively.

Apprich and Licka described using topical chemotherapy to treat canker; the same type of chemotherapy has been successfully used on equine sarcoids.

Dr. Veronika Apprich kindly shared photos and updated the study for this blog report.

The study predicted that, if successful, the treatment would both reduce the amount of time a horse would need to be hospitalized and decrease the rate of recurrence.

The initial study tracked results of treatment of three horses (two warmbloods and one draught horse). Two of the horses had canker in one front hoof; the third horse had canker in all four feet.

Laboratory tests on one of the horses identified the presence of bovine papillomavirus DNA.

The canker lesions were debrided in all the horses before treatment, but recurrence required that two of the horses underwent a second surgical debridement before chemotherapy could begin.

The horses were treated topically with a paste of cisplatin ten times, every other day, for about 20 days; the feet were kept bandaged.

In correspondence since the Congress, Apprich shared information that her team has now treated eight horses, with follow-up available on all of them. Only one horse has had a recurrence, which she explains:

“The only (and really small) recurrence (in one front hoof), which was surgically debrided in a really early stage again and by this cured until now, was seen after 13 months only in the horse with all 4 hooves affected by now; but this was also the horse which had undergone quite intensive treatment other than cisplatin chemotherapy before (at the time of cisplatin chemotherapy this horse had the 4th recurrence of canker).”

This clinical research can add to the information bank on equine canker if two ways:

  1. Treating more cases this way and following up on the success of the treatment may lead to a better understanding of canker and how it may be related to equine sarcoids.
  2. The recurrence of canker is a particularly discouraging aspect of the condition; any treatment that successfully decreases the rate of recurrence, or delays recurrence, will make a difference in owner attitude toward initiating treatment of the horse.

Thanks to Dr. Veronika Apprich for her assistance with details of her study.
