Totilas: Heart Bar Shoes for the Dressage Champion

I've written so many stories about the triple-World Champion dressage stallion Totilas. I've taken so many photographs of him. But you know, I've never really seen his feet. The horse always has bell boots on. They take them off at the edge of the arena, and they put them right back on.

In case you haven't heard of him, Totilas and his rider, Edward Gal, swept the Alltech FEI World Equestrian Games last fall. They took home all three gold medals for The Netherlands. 

A few weeks later, when Totilas was sold by his Dutch owners to German stallion magnate Paul Schockemohle, I wondered if he might very well have bought the horse without ever seeing his hooves. But something tells me that the hooves weren't why he paid so many millions for Totilas.

This is what we saw of Totilas's feet at the World Equestrian Games. There were bell boots of many colors.

I always had the feeling, though, that my time would come. I didn't think or wish that the horse would go lame; his Dutch horseshoer is my friend. I thought maybe there would be an auction of one of his shoes or a celebrity horseshoeing stunt and I'd be there to photograph it. Instead, the horse was sold.

Soon after Totilas was off to Germany, I found this unlabeled Swedish video on YouTube with comments from Dutch farrier Rob Renirie about shoeing Totilas. For true fans, this video will be a revelation, as it actually shows the bottom of one of his unshod feet, something not shown before, to my knowledge.

This video was made a year ago, but I only discovered it after the horse was sold.

A few weeks ago, England's Horse and Hound Magazine did an interview with Matthias Rath, the lucky German rider who has taken over the reins of the great horse. Totilas looked very sporty in the photo shoot by our friend, Dutch photographer Arnd Bronkhorst; he sported stealth-style black leg wraps with matching black bell boots. A new image!

Right about the same time, this blog started to get queries about heart bar shoes. There is nothing unusual about that. We get queries at all hours of the day and night. It is laminitis season, so questions about heart bar shoes seem logical in April. But these questions were on the order of: "Why would a dressage horse wear heart bar shoes?" Another asked me point-blank if a heart bar shoe meant only one thing: laminitis.

This image is mirrored from the Horse and Hound web site, where you can see the full gallery (and at a larger size) of Arnd Bronkhorst's photos of Totilas and Matthias Rath. Image by Arnd Bronkhorst © Horse and Hound. See lots more images of Totilas on Arnd's website: www.arnd.nl
A quick google told me what was going on. The rumor on  the Internet was that Totilas was wearing heart bar shoes. Except it wasn't a rumor. On the Horse and Hound web site, a new set of Arnd's photos was posted from the same shoot that had been in the magazine, but this series showed the bottom of the horse's feet (in bell boots, of course). And he is undeniably wearing heart bar shoes on both front feet.

Note: When I first posted this story, I did not know that the photos were taken by Arnd Bronkhorst, although I should have guessed! You can see (and purchase) pages and pages of photos of Totilas, of Rob Renirie, and of whatever else in the entire horse world you'd like to see on Arnd's searchable database of extraordinary horse photography. You'll also see where some of Hoofcare and Lameness's favorite and award-winning magazine covers originate! Arnd's website is one of the very best things on the Internet, in my estimation.

I still wasn't sure I should write anything about this great horseshoe expose. I talked it over with a friend; I could tell she wasn't impressed. I emailed Rob Renirie and Matthias Rath. But I knew that if I didn't write about what heart bar shoes were all about, the rumor mill wouldn't have an anchor. Now I just have to hope that people find this information.

This heart bar shoe made by Jim Blurton Tools in Great Britain is somewhat similar to the shoe that Totilas wears. It has sculpted heels, which provide support under the heel bulbs but are designed to have less steel at the back of the foot so the horse is less likely to step on it. A heart bar shoe for a lame horse might be oval in the heel area (called an egg-heart bar) or it might be straight across the heels, creating a firm platform and base of support both for the horse's weight and for the farrier to be able to forge the steel into the tongue. A machine-made shoe allows the luxury of pre-sculpted heels; horse owners complain a lot when horses pull off expensive shoes. (See Jim Blurton Bar Shoes page for more information.)

Then on Wednesday, I received notice that Totilas had to cancel a public appearance, and that he was suffering from an abscess in one of his left front heels. That transparency impressed me as much as the news saddened me. The message was that he needed a few days off but that he'd still begin competition the first week in May.

What's wrong with Totilas? Maybe nothing. A heart bar shoe is recommended for something as minimal as to help increase sole growth on a flat-footed horse or to relieve pressure on the hoof wall when the hair line at the coronet is uneven, so it can grow more uniformly. It might be a rest shoe. Or it might be a full support shoe for a lameness issue, but it's doubtful that his backers would still be training him.

The key to a heart bar shoe is how much, if any, pressure is applied to the heart bar. Pressure is key for laminitis therapy; support is key for sport horses in need of wall or sole rehabilitation.

As far as disorders that respond to heart bar shoes are concerned, there is a long list of conditions that might improve with a heart bar shoe if it is fit properly. It is one of several shoes that a vet and farrier will try out to see how the horse tolerates it. Some horses barely tolerate frog contact, let alone any pressure. Other horses thrive on it.

This is a heart bar shoe handmade for a horse with laminitis. Every heart bar is different because of the shape of a horse's heels and foot, and the width and length of frog. I believe that the horse's toes had been resected (hoof wall cut away). With laminitis, the only sound place to nail may toward the heel area. David Gulley/Mark Caldwell photo.
So what about these shoes for laminitis? First of all, if Totilas had laminitis, there would likely be a pad and some type of support material filling his foot, and he wouldn't have been schooling in front of a photographer a month ago.

I checked in with James Gilchrist of Wellington, Florida, who probably shoes more Grand Prix dressage horses than anyone in the USA. He concurred that there are many reasons why a horse would be shod with heart bar shoes during the off season. He immediately quoted Rob Renirie, however, in stating that, when the time comes for competition, the best shoeing is also the simplest, most uncomplicated shoeing.

James Gilchrist (right) spoke on sport horse farriery at the 3rd International Equine Conference on Laminitis and Diseases of the Foot, along with fellow sport-horse specialist Aaron Gygax, left, of Switzerland, in 2005.

James Gilchrist didn't seem surprised that a grand prix world champion horse being used for breeding and not competing would be wearing heart bar shoes in March.

That said, James and I both see dressage horses competing at all levels with heart bar shoes on. Some vets and farriers say that they like bar shoes, particularly in deep footing or if the horse has had suspensory problems, because the horse will "float" more and not sink into the footing. If a horse sinks too deep, he has to work harder to breakover, and the strenuous upper level movements can lead to early fatigue. The shoes should match the footing, but the footing shouldn't be too deep and strain the horses anyway.

Another aspect of heart bar shoes is that they come in, or can be made in, all weights and thicknesses of materials. You can pop on a set of beautiful Imprint plastic glue-on heart bar shoes right out of a box. Laminitis calls for a lot of seating out. They can be made from fullered steel, British style, or aluminum, American show horse style. As big as a Shire's hoof, as tiny as a Shetland's.

But for all the talk about heart bar shoes, what you don't hear about is that they are one of the most difficult shoes for farriers to learn to make and/or fit. And they must be truly fit to the foot and to the frog. Many farriers don't like them either because they have had bad experiences with them or they never bothered to learn to use them correctly or they prefer other methods that they feel will achieve the same results.

Possibly as many horses have gone lame because of heart bar shoes as have gone sound. The farriers who know how to fit them have a very valuable skill. But a skilled farrier can still meet a horse who won't tolerate the shoe; the skilled farrier recognizes that, as well.

Back in the 1980s, the late Burney Chapman of Lubbock, Texas gave the world the Great Heart Bar Shoe Revival. And it's still going on, as this week's news from Germany attests. (Photo © Hoofcare Publishing)

Heart bar shoes were dug up from the old shoeing textbooks and re-introduced to the horse world in the early 1980s by a farrier from Lubbock, Texas named Burney Chapman. 

Burney isn't with us anymore. He died of brain cancer eleven years ago, when he was just 57 years old. But if his shoe is helping Totilas, our friends in Germany should turn toward Lubbock, Texas and tip their hats to the man who made it possible. Totilas should take a little bow.

Somewhere, Burney Chapman is smiling.

It all comes down to this: if Totilas is sound under his new rider the first week of May when he comes back into competition after almost eight months off, we'll all be smiling. I am sure I speak for the universe when I say that no one wants that horse to be lame. He was born to be in motion.

All Clear! Quarantine Lifted at Cornell Vet School's Equine Hospital

Two weeks ago, this blog reported the closure of the Equine Hospital at the Cornell University College of Veterinary Medicine in Ithaca, New York after a foal died and later tested positive for Equine Herpes Virus. A gelding at the hospital also became ill.

Cornell voluntarily closed its hospital doors on March 30 and worked with animal health authorities from the State of New York to initiate the proper biosecurity procedures.

Today I learned that the Equine Hospital re-opened yesterday afternoon.

“The quarantine on Cornell’s Equine hospital barns and several other barns owned by the college was lifted yesterday afternoon after the results of twice-daily temperature-taking and testing by nasal swabs during the quarantine did not reveal any EHV-1,” wrote Stephanie Specchio, Director of Communications at Cornell University College of Veterinary Medicine in an email this afternoon. “The Equine Hospital is now operating under normal status.”

Although the Hospital and its barn are now open, the Equine Research Park and the Annex remain quarantined through April 19; a different quarantine schedule was established for those locations.

The following additional information has been posted on the vet school’s web site: “Presently, there are no horses exhibiting symptoms of EHV-1. While we believe there is a low risk of exposure, we are taking every precaution to ensure the health and well-being of all animals.

“The quarantine was lifted from the equine hospital barns and some additional college-owned barns on April 12, after temperatures (taken twice daily) and additional tests conducted on all horses indicated that EHV-1 is not present.”

Farrier History: Negro Ellick Shod Horses for the Confederacy in the Civil War

Today is the 150th anniversary of the beginning of one of the darkest and most painful chapters in United States history: the Civil War. Where I live, every little village has a monument to its men who died in places like Gettysburg and Antietam. The names go on and on. It makes you wonder if anyone came back at all.

I can imagine that in the southern states, the lists could be longer and it would be possible that no one returned.

As much as I read and study about the Civil War, I keep learning new things. For me, the horses are the thing of interest, and the farriers who serviced them, and the foot problems that challenged both horses and farriers.

Farriers for the Union horses were often foreign immigrants. This group looks like new arrivals: their aprons are clean and their hammers shiny.

If you have read this blog for any length of time you know that the Burden Horseshoe played a big role in turning the tide of the War in favor of the Union. Trainloads of horseshoes could leave the factory in Troy, New York and be bound for the huge remount stations or go directly to the front. Not just the cavalry but the entire artillery and the massive kitchens and quartermaster depots moved camp only the horses were shod. And those first machine-made shoes from Troy kept them all moving.

The Confederacy wasn't so lucky. They had a limited supply of iron, and it was needed for munitions as much as for horseshoes. There were no horseshoe factories in the South and orders were given for any raids on Union supply trains to go for two things: cash and horseshoes.

Until recently, I never thought much about who the farriers of the Confederacy were. I knew the Union recruiters met ships in New York and convinced farriers and blacksmiths from all nations to either enlist or to go to work as civilian government horseshoers in the remount stations.

But what about the Confederacy?

This is the enlistment paper for Ellick, an African-American who was brought into military service to work as a farrier for the Confederate States of America, even though it was not approved for white men to conscript blacks into service. This document is preserved in the National Archives in Washington, D.C.

This week I learned that the laws of the Confederacy prohibited the conscription of slaves into military service. But African-Americans were there anyway, in fighting and non-fighting roles, and if authors Kevin M. Weeks and Ann DeWitt are correct, the care of the horses may have been one area where they could have been found. Just take Ellick's case.

Ellick was a farrier for the Confederacy, though he had no rank and drew no pay. It's impossible to know if he went willingly. It's quite likely that the Confederate army was desperate for farriers and experienced horsemen. Ellick may have played an important role.

Not only did the Union have new recruits with shiny hammers and unmarked aprons. They had mobile forges built on double wheel axles. In front of the forge you see here was a big bellows. The US Army designed and built these to get the farriers and the shoes to the front, where they were needed. (Library of Congress photo)
How amazing is it that the National Archives in Washington would have preserved the enlistment paper of a farrier after that war was over? This is just one example of the millions of bits of fascinating information that lies buried in those vaults of papers.

Who found Ellick? Kevin Weeks and Ann DeWitt are the authors of the new book, Entangled in Freedom: A Civil War Story. Last week their book graced the cover of Publishers Weekly's Special Independent Publishers Spring Announcement Issue. Entangled in Freedom is a young adult novel written as a first-person account of a young African-American serving with his slaveholder in the Confederate Army. The book has already won the Bonnie Blue Society Award. Ann DeWitt runs the web site www.blackconfederatesoldiers.com.

I'd like to thank them for bringing Ellick to my attention, for pulling him out of the piles of papers in the Archives, and for making him come to life. Maybe we'll never know much about Ellick but for today, he's the star farrier on the Hoof Blog and the Civil War is interesting all over again.

Cornell Vet School Equine Herpes Virus Quarantine: Hospital and Barns Closed; Shoeing School, Farrier Shop Open

The following information is provided as a public service for horse owners and horsecare professionals.

The world-famous horseshoeing school and farrier shop at Cornell vet school is remaining open during the quarantine, according to resident farrier Steve Kraus.

The New York State Department of Agriculture and Markets’ animal health officials and veterinarians from the Equine Hospital at Cornell University are investigating two confirmed cases of Equine Herpesvirus 1 (EHV-1) in New York State. Both horses listed as cases of EHV-1 were inpatients of the Equine Hospital at Cornell University, and could have potentially exposed 69 other horses.

EHV-1 is a common viral infection of horses that is highly contagious and exhibits an array of symptoms, ranging from no clinical signs to neurological disorders.

Equine Park

New York State Veterinarian Dr. David Smith said, “While a common virus in horses, we are taking this situation very seriously given the large number of horses that have potentially been exposed to a highly communicable and sometimes fatal disease. To date, no other horses have showed signs, nor tested positive for the virus. However, this serves as an excellent reminder to horse owners that they should always be cautious of introducing new horses with an unknown disease status.”

“We recognize the seriousness of the Equine Herpesvirus Type 1 and other infectious diseases,” said Dr. Alfonso Torres, Associate Dean of Public Policy at the New York State College of Veterinary Medicine at Cornell University. “Thanks to our surveillance systems and access to highly sensitive testing at the New York State Veterinary Diagnostic Laboratory, we were able to rapidly identify the infectious agent and implement appropriate actions immediately to prevent the spread of the infection.”

This incident involves two confirmed cases of EHV-1 in New York State. One was a one-day old foal that was admitted to the Equine Hospital on March 18. The foal died two days later of pneumonia, and tests revealed the presence of EHV-1 on March 25.

During the same time, a gelding was being treated at the hospital for a spinal injury. It was discharged on March 22, but became severely ill and showed neurological symptoms after arriving back at its home farm. This horse tested positive for EHV-1 on March 30. The gelding is now recovering.

In response to the two confirmed cases, both the gelding’s farm and the Equine Hospital were quarantined immediately, restricting movement and access to animals at both facilities. Horses at both facilities are being monitored closely and having their temperatures taken twice daily. So far, no animals have exhibited a fever attributable to EHV-1, which would be an early warning of the virus.

At the hospital, polymerase chain reaction (PCR) tests have also been completed for four consecutive days on all current patients. The PCR samples from all animals in the hospital are negative, indicating that no virus shedding is occurring.

As part of this on-going investigation, the Department of Agriculture and Markets is working to determine the source of the infection, as well as to identify and isolate potentially exposed horses. In doing so, Cornell has been contacting all referring veterinarians and the owners of 69 other equine patients that may have been exposed while at the Equine Hospital. The Department is also communicating with private veterinarians to provide information related to this situation, and is prepared to follow up on possible quarantines of trace-out barns of the 69 potentially exposed horses, if necessary.

At this time, neither the Department nor Cornell know of any other animals that have showed signs or tested positive for EHV-1 in association with this incident.

Nearly all horses in their lifetime will be exposed to EHV-1 at some point, and therefore it is difficult to detect as it takes on a wide range of manifestations, from a complete lack of clinical symptoms, to pneumonia, to abortion in mares, to full-blown fatal neurologic cases. The virus does not persist in the environment and is neutralized by hand soap, alcohol-based hand sanitizers, and sunlight. Transmission of the virus is mostly via direct contact with infected materials.

EHV-1 does not affect humans or dogs, cats, cattle, sheep, goats, pigs or birds; however, alpacas and llamas can be affected.

If you are the owner or caretaker of a horse that was or has been at the Equine Hospital at Cornell on or after March 18, 2011 or that may have come in contact with a potentially exposed patient, the following guidelines are recommended:
  • Isolate your animal, if possible. It is always recommended that horses returning from veterinary hospitals be isolated for three weeks when possible.
  • Check your horse’s temperature twice a day for ten days. If the temperature is 102 degrees Fahrenheit or greater, contact your veterinarian immediately.
  • If you care to test your horse, consult your veterinarian. At this time, the preferred test is PCR analysis performed on nasal swab specimens.
Since March 30, 2011, the Equine Hospital at Cornell University has been quarantined. No movement of animals between the equine barns and other Cornell facilities is permitted at this time, and the hospital is only accepting emergency cases.

Out of an abundance of caution, the quarantine at the hospital will remain in effect through April 11.

For more information on EHV-1, visit the American Association of Equine Practitioners website or check USDA APHIS brochure on the virus.

Equine Biomechanics on Broadway: Technical Videos Preview What the Audience Won't See When War Horse Opens in April


If you're new to War Horse, this video from London explains a bit about the play and shows some scenes of the horse puppet in action.

Everyone will soon be talking about the USA Broadway premiere of London's long-running hit stage play, War Horse. I've been writing about it on this blog and everywhere else that would allow me since it launched in 2007. Now we have a chance in the USA to experience the story of Joey the plow horse sent to France in World War I.

Joey's not a real horse, of course. He's a puppet, and one of the most clever puppets you'll ever see. But a few minutes into the play, you'll completely forget that he's made of cane and cloth and that there are two people inside him.

I'm so excited to share this video with you. This TED lecture explains the origin of the puppets with the creators from South Africa's Handsprings Puppet Company.

War Horse has played to sold-out audiences in London for the past few years, and it has brought attention to the fact that a million horses died in World War I.  It's an anti-war story, of course; Joey belongs to a boy who is heart-broken when his horse is sold to the British Army. He sets off to rescue his horse who is meanwhile deep into the war. What the boy finds carries quite a moving message.

In this video, you'll meet War Horse's equine choreographer, Toby Sedgwick, whose job it is to make sure that the puppet moves and "acts" like a real horse. This video also has great close-ups of the design of the feet and legs, and was also shot for the New York premiere.

Joey's movements are so life-like that I know Hoof Blog readers will want to know more about how he was built and how he works. His creators gave a TED lecture recently, which was released today, so grab a cup of coffee and invest the next 20 minutes in learning about an outside-the-box application of your knowledge of equine biomechanics.

When you go to see the play, you'll forget all about biomechanics and be absorbed into this horse's-eye-view of the world at war. You'll soon understand what all the buzz is about, and why so many creative people have given so much to make this play such an amazing experience for theater-goers. Make sure you're one of them.

If you can't make it to Manhattan, War Horse is supposed to have shows in Toronto and Los Angeles in the future. And Stephen Spielberg's Dreamworks film of War Horse will be released by Disney on December 28, but with real horses. It was filmed in Dartmoor, England last spring.

I'll see you on Broadway! War Horse opens at the Vivian Beaumont Theater at Lincoln Center on April 14, 2011.

Laminitis Research: Equine Insulin Resistance Does Not Respond to Metformin Medication; Diet and Exercise Remain Key to Laminitis Prevention

Morning all
Researchers in Australia tested the effects of a human medication, metformin, on ponies with insulin resistance, a condition that puts horses at risk for developing the endocrine or metabolic form of laminitis. The medication had no effect. (J.A. Holland image)
New research on the pharmacological management of the condition of insulin-resistance in horses and ponies has suggested that diet and exercise are still key in any management plan.

Insulin resistance (IR) is defined as the diminished ability of a given concentration of insulin to exert its normal effect on glucose dynamics in particular. This causes the body to keep releasing more and more insulin in order to elicit an effect. This may be one of the most predictable factors that determines whether a horse or pony could be more susceptible to what is commonly known as the "endocrine" or "metabolic" form of laminitis.
The University of Minnesota College of Veterinary Medicine's Equine Genetics and Genomics Laboratory explains insulin resistance this way:
Insulin  is a hormone involved in the regulation of glucose (sugar) levels in  the blood and tissues of the body.  In response to feeding, insulin is  secreted by the pancreas into the blood stream. Insulin in the blood  stream directs the glucose (sugar) absorbed from the food into the  body’s tissues including liver, fat and muscle.  Insulin resistance  occurs when insulin no longer has a normal effect on the tissues. In the  insulin resistant horse, the pancreas releases insulin into the blood  stream, and the insulin arrives at the tissues and binds the cells,  however the glucose enters the tissue cells at a much lower rate than  normal. This lower rate of glucose uptake into tissues results in higher  levels of blood glucose.

Horses and ponies compensate for  insulin resistance by secreting even more insulin into the bloodstream  in order to keep the blood glucose concentration within the normal  range.  Therefore, horses and ponies with EMS (Equine Metabolic Syndrome) have a higher  concentration of insulin within the blood, which can be measured to  determine if insulin resistance is present.
An important goal for owners and vets should be to prevent IR from developing, or to manage it before it contributes to the development/progression of other potentially life-threatening conditions. While the correct management of energy intake and exercise levels is thought to be essential, in some cases medication is also considered, especially when increased exercise is not possible. With no licensed drugs currently available for the treatment of IR in horses and ponies, off-label medications used for IR in humans are sometimes prescribed.

A trial was conducted by the School of Animal and Veterinary Sciences at Charles Sturt University in New South Wales, Australia and the Department of Clinical Studies at the University of Pennsylvania's New Bolton Center, in collaboration with the Waltham Equine Studies Group in Great Britain.

The study's intention was to confirm the positive effect of the human medication metformin on insulin and glucose dynamics in insulin-resistant ponies so that this treatment could be used as a positive control in other studies.

Glenys Noble BAppSc(Equine Studies) PhD, along with PhD candidate Kellie Tinworth BSc(hons) MSc, carried out the clinical trial in Australia. Six insulin resistant, non-obese ponies were repeatedly monitored by means of a frequently-sampled intravenous glucose tolerance test (FSIGT). Metformin ia a drug reported to enhance insulin sensitivity of peripheral tissues in humans without stimulating insulin secretion. It was administered twice-daily (15mg/kg BW BID) to three of the ponies for 21 days.

Meanwhile, the three remaining ponies formed a control group, and each received a placebo. After a wash-out period, the treatments were crossed over.  A Frequently Sampled Intravenous Glucose Tolerance Test (FSIGT) was conducted to evaluate the level of insulin resistance before and after each treatment.  The ponies' body weight, body condition score and cresty neck score were also assessed. They did not change during this study.

Ray Boston MSc PhD
is Professor of Applied Biomathematics in Clinical Studies at the University of Pennsylvania's New Bolton Center. He analyzed the data using MinMod, a computer program to calculate glucose effectiveness and insulin sensitivity from the frequently sampled intravenous glucose tolerance test, and Stata 10.1 statistics analysis software. No change in insulin sensitivity or glucose dynamics was seen under the control conditions or in response to the dose of metformin given in this study to these ponies.  

What does this study mean to horse owners? Clare Barfoot RNutr is the research and development manager at the British feed company Spillers®; she reviewed the research and said: “Although clinical trials with metformin are ongoing, this trial was consistent with our previous work showing that the bioavailability of metformin in horses is poor, and chronic dosing at these levels may not achieve therapeutic blood concentrations.”

She continued: “On this basis it would seem that a fiber-based diet that is low in starch (found in cereals) as well as  (being low in) sugar and fructans (found in grass), in conjunction with regular exercise if possible, is still the safest and most effective way to manage insulin-resistant ponies. It is important to recognize that, even if other doses of metformin are shown to be beneficial in the future for certain sub-groups of animals, full consideration to diet and management should remain a key tactic.”

The Waltham® Equine Studies Group, headed up by Dr Pat Harris MA PhD, VetMB DipECVCN MRCVS, provides the scientific support for the Spillers® and Winergy® brands sold in Great Britain.

Midnite: Mini's Back on All Four Hooves Thanks to Prosthetic Boot

Midnite is a miniature horse at a rescue farm in North Texas; he has lived his whole life with a deformed hind foot that is missing its coffin bone, according to the Rescue.

Have you heard about Midnite? His story is all over the Internet and television news shows today. This young miniature horse was a law-enforcement rescue case who hopped into Ranch Hand Rescue in South Argyle, Texas on three legs. He couldn't put his left hind hoof down because...well, because it just wasn't there.

Midnite may have come to a safe, new home, but even as he gained weight and his overall health improved, he wasn't cheering up and that was a challenge. Almost as much of a challenge as simple movements like laying down, or getting back up. Scampering around with the other animals in the paddock wasn't an option. He won over the hearts of everyone at the rescue farm, especially director Bob Williams, and Bob decided to see if they couldn't do something to help the little guy.

The first attempt was using a donated Soft-Ride hoof boot (thanks, Soft-Ride!), with its removable gel-pad orthotics. These rehabilitation boots are familiar to many Hoofcare and Lameness readers, and lucky come in a vast array of sizes--even tiny enough for a mini. They taped the boot on the stump of his pastern each day and removed it each night. The staff massaged him, and powdered his stub, and they learned a lot about three-legged horses, especially how they need to re-disribute their weight after a long time of not using one of their limbs.



Here's a YouTube interview with Lane Farr, designer of the prosthetic clamshell boot.

From seeing a bit of improvement with the Soft-Ride boot, the rescue team, led by Bob Williams, scratched their heads and wondered what a human orthotics designer might be able to design for a tiny artificial hoof replacement.

Enter Lane Farr, a prosthetic designer with a lifelong connection to horses and a way with carbon graphite and fiberglas and gel foam. Lane designed a prosthetic support device that he told me both allows the little horse to bear some weight on what passes for a hoof, and also transfers some of the weight to a passive load share state rather than the direct load straight down the bony column through the pastern.

Lane told me that there is no medical history on the little horse,but that the assumption is that the deformity is congenital--it was present at birth.

The support/weight transfer boot has been through a couple of stages of re-design and Midnite is now able to run with it on, as you can see in the AP video.

I thought you might like to see these other videos, which show the boot up close. I'd love to see the inside of the boot and the gel construction and will ask Lane and Bob if we might get pictures of that. They're both busy with reporters today, and I know how they can be.

Hoofcare and Lameness apologizes for the ads on these and all videos. They are embedded by the hosts and they're just there, sorry. These television stations and media outlets are generous to allow Hoofcare and Lameness to embed the videos, or to post them on YouTube the way that Associated Press did. Many won't allow embedding at all, which is why many great stories can't be posted on the Hoof Blog. But for those who do work with us--the ads are ok, even though I will probably never need an orthodontist in Fort Worth! It seems like the least I can do for the privilege of sharing videos with you.

This short video has some good close-up views of the boot.

Finally, a big thanks, hats off and high-five to Bob Williams, the Board of Directors of Ranch Hands Rescue, Prostheticare, and Lane Farr for all their hard work on behalf of this little horse. I know some people say, "So what? Why bother?" but I would remind you that these are real people, without a lot of money to invest in a single case and who are pretty much self-taught, who took a risk and came up with a successful, low-impact way to help this horse.

What none of these videos tell you is that Ranch Hand Rescue could use your donation to help Midnite and all their other rescued animals. Here's a direct clickable link to their PayPal donation page. Please help them out!

It is true that with a $14,000 price tag, this clamshell design isn't going to sold every night on eBay, but this story has received more press than any story since Molly the Pony back in 2008, and I can tell you that that story had an amazing impact on the way that people think about going the extra mile and burning some extra brain cells before they give up on a horse.

I'd also like to thank Bob and Lane for taking the time to return my pestering calls when they have way too much going on already. Like me, they think you all, the readers of this blog, might be the ones who can make a difference.

Please prove them to be right.

Cheltenham's the Place to Be Today


Last year at Cheltenham, the celebrity riders, trainers and familiar faces got together and recorded a song about the race meet that they all love so much for a charity fundraiser.



In Gloucestershire, England they run a four-day National Hunt race meeting that is like no other in the world. It's like Saratoga on steroids: the best horses, the (hopefully) best weather, and a few hundred thousand of your very best friends all make sure that you have an unforgettable time.

Today, Friday, is the last day and it all culminates in the Gold Cup. Old rivals--and stablemates--Demman and Kauto Star may be eleven now, but they're heading out again. Kauto Star has won it twice. Denman won it once and was second twice. Oh, and there are some other horses in the race, too, like Imperial Commander, who beat both of them last year. (Denman was second, Kauto Star fell.) That these three Gold Cup winners could be back to challenge each other again is the flip side of the chronic unsoundness we take for granted in racehorses. These jumping horses, at their age, must have tendons of steel. The Gold Cup is three miles, two furlongs...with hills.

The sad thing is, this will probably be their last meeting. Safe run, you old boys!

St Patricks Day: It's Never Easy Being Green


green horse hooves
Is there anything people won't paint green on St. Patrick's Day? Between blinders and check reins, maybe these horses probably can't see what's happened to their feet. Photo by chautauquatourist
