What's Wrong with This Foot?

by Fran Jurga | 15 May 2009 | Fran Jurga's Hoof Blog

Foot infections are curious things. A reader sent this in and I thought I'd share it because it seemed unusual to me. Perhaps different parts of the world have different types of foot infections; this horse lives in a very wet climate.

I know that we have only just begun to learn about immune system disorders in horses and how they may affect the feet. There's new information coming...but there is also much to be gleaned by going back and reading the old books.

It is always said of infections like canker that it affects one horse in 100 and then there is always the story that makes you scratch your head.

The city of Cleveland is said to have had an outbreak of canker in the winter of 1894 that practically shut down public transportation because so many streetcar horses were lame; they blamed it on the salt mixture that was used to melt the snow and ice off the tracks. The city switched to sand the next year and never had a mass lameness problem again.

Hoofcare & Lameness #77 had a special section on foot infections--deep sulcus thrush, canker, pemphigus, insect bites, pastern dermatitis, vasculitis, lymphedema and fungal-type infections of the hoof wall. We're now working with Dr. Knottenbelt at the University of Liverpool on an update of his work on some immune disorders that affect the foot and pastern and hope to have some of his brilliant work to share with you soon.

But in the meantime, please tell me--and other blog readers--more about this foot.

Warning: Lawn Clippings Are Not Good for Horses!

by Fran Jurga | 14 May 2009 | Fran Jurga's Hoof Blog


Golden Light, originally uploaded by Dan65

Vet and farrier readers: This post is your clients--please share!

There’s no mistaking that sound: the mowers have started. Is there a more sure sign of summer?

If the sound of mowers is the first sound of summer, the second should be the sound of horse owners explaining to landscapers, lawn crews and neighbors that, while the thought is kind, it is NOT okay to dump mulch mower bags or raked-up grass clippings into horse paddocks or feeders.

Some people will think they are doing some clever recycling and being kind of animals, but the opposite is true.

Wet green lawn clippings are often left in mower bags or in piles, where they start to ferment quickly. A hungry horse will nibble at the clippings, and the fermentation (and the gastric gases it creates) in the gut can be deadly. We won’t even talk about the chemicals from herbicides and fertilizers!

Horses can also choke on clumps of grass clippings.

Laminitis might be a real risk too, particularly for horses with other considerations like insulin resistance, and for ponies.

Here are some suggestions, especially if you have horses that are at risk for colic or laminitis problems:


If your turnout borders an area served by a landscape crew, talk to the crew foreman. If you are off at work and leave your horses turned out, consider posting a sign on your fence.

If possible, make sure that town and county road maintenance crews that mow roadsides and median strips know not to dump trimmings into horse pastures.

When you arrive home in the evening, check your pastures, paddocks and arenas, especially along any sections facing neighbors or the road to make sure nothing has been dumped.

Consider writing a letter to the editor of your local paper, and post this article in your feed store and any stores that sell lawn mowers or at nurseries and farmstands that sell plants.

Chances are, your neighbors and community members are completely unaware of the dangers of grass clippings to horses, ponies, donkeys and mules. Remember, they probably mean well.

Do you have experiences with horses suffering the ill effects of grass clippings? Or neighborhood relations suffering? I know this is sort of a suburban issue, but that is where so many of our horses live these days...or the suburbs have come to them!

I was at a party once when a gentleman came up to me and smugly introduced himself as a neighbor to the boarding farm where my horse was living. He informed me that he was kind to animals and dumped the clippings of his vast chemical green carpet into my mare's paddock. I was speechless, and had to be, as the farm's relationship in the neighborhood was at stake. You might need that neighbor at a zoning or board of health meeting sometime.

Mine That Bird Started His Career With Victor In His Camp

by Fran Jurga | 12 May 2009 | Fran Jurga's Hoof Blog
In the race to explain Mine That Bird's Derby zeitgeist, no one has offered the Roswell alien connection...yet. If that horse runs that way again in the Preakness, we might want to go back and look some more at the history of the town that sent him to the Derby and what happened there on July 7, 1947.

Mine That Bird's dazzling victory in the 2009 Kentucky Derby has been explained away by the longest list of reasons that any great moment in sports has ever enjoyed. Or suffered, depending on your point of view.

The most popular, of course: a brilliant, hair-raising, let's-see-that-again ride by jockey Calvin Borel. Agreed!

A regular reader of this blog (or so he tells me, to my delight), Dr. Sid Gustafson, offers some equine sports science reasons this week in the blog of The New York Times, The Rail: the change in altitude meant that Mine That Bird was running with New Mexico oxygen capacity at a Louisville elevation. Gustafson also saw some ethereal quality in Mine That Bird's hooves that he described as "mudders". Oh, and the colt has big nostrils. The better to breathe that oxygen-depleted high desert air, I guess.

Others point to his sire, or his career on artificial surfaces creating a zeitgeist effect when he switched to good old (if muddy) Churchill Downs dirt. And there there was that two-mile gallop before the Derby (see elevation switch, above). And the trailer ride, all that way from New Mexico, that must have had something to do with it. And the reasons go on.

No one has mentioned that he hails from Roswell, New Mexico, as does his new jockey, Mike Smith. And we all know what made that place famous on July 7, 1947. I'm surprised that no one has suggested an alien connection aided the horse in his zip along the rail on the first Saturday in May--Yet, that is!

I wasn't particularly looking for a reason, I was just enjoying the moment, until the other day that I found out that this little horse's past includes plenty of time spent with a familiar face around the Hoofcare and Lameness scene.

It seems that Needham/Betz Thoroughbreds in Kentucky, where Mine That Bird was born and raised, employs a very special farrier to take care of their young stock. I don't know how much you know about how foals are cared for on Kentucky Thoroughbred farms, but it is not unusual for a farrier and his or her crew to go through dozens of foals and yearlings in a day.

Except for one. There's one truck that stays in the driveway longer than the others, and one farrier who may only get through a few of the foals on the list on any given day. And when you ask him, three years later, about a particular foal, he'll not only remember the foal's dam, he'll remember the feet. And he'll be happy to tell you about them. In detail.

That farrier would be Victor Camp, of course. A transplanted New Yorker who looks like he'd be more at home in Greenwich Village than rural Kentucky, Victor has chosen the Lexington area for his mid-career farrier practice base and recently bought a home in Winchester, Kentucky. His practice is split between Thoroughbred farms and sport horses and his caveat with all his clients is that he be allowed time to work on each horse, consider what its most appropriate care should be, and take the time to do it properly.

Victor learned about horses and horseshoeing in a different world, in and out of the rarefied estates of Westchester County, New York where he apprenticed to older smiths in the 1970s when the fine horses he worked on required a level of craftsmanship that could be recognized but was rarely taught. He developed an analytical hoof theorist's angst that has made him the Woody Allen character of the farrier world today--all in a world where the answers to many of his questions are prefaced with, "Well, no one ever asked me that before." And also in a world where many don't ask questions at all.

When I tracked Victor down to ask him about Mine That Bird, he had no idea that anyone outside Lexington knew of his involvement with the gelding, but he was quick to launch into a recollection of what it was like to work at Needham/Betz two years ago when Mine That Bird was being prepared for the yearling sales. Victor continues to provide services at the farm.

"He was small," Victor recalled, "and I was concerned about him." Mine That Bird is not Victor's first Derby winner; Victor also prepped the feet of Monarchos, another somewhat surprise winner of the Derby, for his career ahead.

Victor advised, "I like to say that every foot I handle is handled like that colt is the next Derby winner. Every care must be taken to ensure it has the best foot possible underneath it!"

Victor had high praise for farm owner and breeder Judy Needham, whom he said was a "hands-on" owner who would often be in the barn and even hold the foals and yearlings for him, and discuss their development and sales plans as he worked. He particularly praised Needham for not pushing him to over-correct Mine That Bird's toe-out conformation, on the right front. "She said to give him time, and that's what that horse needed," Victor recalled. "That's the sign of a good owner, one who is willing to give a young horse a chance to come around rather than pressure the farrier to crank on these babies to look better by a sale date. I surely did not want to force him."

By now, everyone knows that Mine That Bird did not break $10,000 at the yearling sale.

Victor admitted that he was mowing his lawn when the Derby was on, and forgot all about watching it.

Victor remarked that Mine That Bird was a late foal, and that he could still be developing, particularly in his chest, a point on which co-owner Dr. Leonard Blach concurred in an interview with Hoofcare and Lameness earlier this week. Victor said that there are many reasons why a horse toes out--whether from a rotational deviation, an angular (joint angulation) deviation, or a combination of the two, in the pastern, fetlock and/or knee joints.

"By the time the horse is three, his pectorals should be filling in," Victor said, "and lots of these toed-out horses have figured out very well how to compensate. Then the muscles fill in. He might be ok. I'd like to see him."

Might be ok? Someone should show Victor the replay of this race.

The record books are full of horses who ran for years in spite of their imperfections--Sir Barton, Swaps, Assault and Buckpasser are four of the all-time great champion racehorses profiled in this blog recently--horses who ran on their hearts instead of their hooves.

Perhaps sometimes the blemished ones ultimately outrun their stablemates, the ones who had all the splints and braces and surgery and special shoes to make their toes point straight ahead on the day it counted.

For so many colts, the most important day of their lives, the day that counts, is the day of that yearling sale. But Mine That Bird was looking at a different calendar. For him, it was all about May 2, 2009.

Too bad Victor had to mow his lawn.

Badminton 60th Anniversary Horse Trials: The View from Below

by Fran Jurga | 9 May 2009 | Fran Jurga's Hoof Blog

In England this weekend, the 60th galloping of the Mitsubishi Motors Badminton Horse Trials is well underway in Gloucestershire. The photos are a little slower than the news is getting to me, but when they get here, they're wonderful.

Badminton is the world's most prestigious three-day event, rate four-stars, and this year is even having decent weather, except for high winds during the dressage that ruined some people's well-laid plans.

These photos are from Wednesday, at the first vet inspection. In this photo, you see a horse's hooves being oiled to insure that the vet will not pick them up. But they'll look nice. Other horses looked to have a hard, high-sheen coating applied, rather than the classic oil. Whoever is at work here is a confident woman who doesn't fear getting hoof oil on her expensive bracelet. So it's true what they say about event riders being fearless.

The hooves of experience shown here are those of the famous Toytown, who has had such bad luck lately. The cowboy boots belong to Zara Phillips, granddaughter of Queen Elizabeth. The former World and European champion event horse under Phillips, Toytown's 16-year-old hooves look like they have been around the block, and he's had more than his share of lameness problems, including being knocked out of the Olympics last year. Sadly, he was retired on cross-country today after bobbling some fences and getting hung up. Zara did the right thing. Her second horse, Ardfield Magic Star, went lame on cross-country and was also retired. Zara's father, US eventing coach Captain Mark Phillips, won Badminton four times.

Here's Emily Llewellyn with Society Spice, who made it through cross-country. I went through all the preliminary horse inspection photos and it looks like a much smaller percentage of horses is shod with toe clips this year, although it seemed that most of the horses in the top 20 after cross-country were predominantly shod with toe clips, which is interesting in itself. There looked like some glue-ons, too and lots of very highly manicured hooves for the inspection--I wonder what they look like now. Last year's best-shod horse, Valdemar, did not pass the first inspection.

The fashions that some of the riders don for the horse inspection are pretty wild (but fun). Both of these riders chose clothing that, when you look closely at their horses' legs, which is what the ground jury will do, their clothing does not distract from the horses' action or coloring. Smart move.

Check back on Sunday (or maybe Monday, depending on when they supply the news) for announcements about the Best Shod Award and the ultimate winner.

Pioneer Equine Hospital: Bigger and Better Things in Store for Lameness Referral Practice in Calfornia

by Fran Jurga | 9 May 2009 | Fran Jurga's Hoof Blog


One of the leading veterinary referral hospitals in the United States is stretching its legs in its new building. Pioneer Equine Hospital in Oakdale, California has moved to a new building that gives them plenty of space for their lameness specialty practice and the surgery procedures that are their specialty.

Dr. Brad Jackman is now the owner of Pioneer Equine Hospital; former owner Dr. Jerry Black also still practices from the clinic. Behind Dr. Jackman you can see his pride and joy: the new hospital's high field MRI, Pioneer will be only the second hospital in the United States to offer MRI with a 1-tesla super conducting electromagnet from Oni Medical Systems.

The practice was featured in a newspaper article in yesterday's Modesto Bee, which you can read by clicking here. The Bee made a special video format for The Hoof Blog to be able to host the little video clip of a horse's plantar digital neurectomy (roughly translated: transection of the nerve to the back part of one hind foot) that I thought you all might find interesting, as well as the familiar face of Dr. Brad Jackman.

The neurectomy was performed by Dr. David MacDonald on a 20-year-old Warmblood-Thoroughbred cross with a history of chronic foot pain.

As to who's manning (or womanning) the farrier shop that has been built at the new facility? The hospital's web site lists longtime Pioneer consulting farrier Rocky Armitage and Rob Dugo. The one at the old hospital was built for and by our friend the late Emil Carre, who provided farrier services for the hospital in its early days. I still miss him, and I'll always wish Dr. Jackman and the hospital well.

All photos and the video accompanying this article are the work of Brian Ramsay at the Modesto Bee and are mirrored from that site. Thanks very much to Brian and the Bee for working with The Hoof Blog to bring you inside the new Pioneer Equine Hospital.

Hoof Research Road Show Premieres This Weekend: Pollitt-Hampson Laminitis and Wild Horse Hooves Headline in Australia

by Fran Jurga | 7 May 2009 | Fran Jurga's Hoof Blog

Dr. Pollitt is known for his hoof-related research but part of his ability to get people to listen is his dazzling imagery. These images are from a series of CT scans of a foot. (©Chris Pollitt/AELRU image)

A couple of weeks ago, there was a street scene here in Boston that was wilder than anything since the Red Sox won the World Series. U2 was in the town. That's not so unusual in itself--the band might play Fenway Park or some other huge venue and sell it out for three or four nights of legendary concerts.

But this was different. They secretly booked a tiny concert hall in the suburb of Somerville.

I can remember, vaguely, that the Rolling Stones did something similar years ago. They wanted to play a small, intimate little theater where they could see the audience and judge how the music was received.

The same thing is going on this weekend in the southern end of Australia, where Dr. Chris Pollitt and his PhD candidate assistant Brian Hampson are quietly opening a new series of lectures on laminitis and hoof research. They'll be at the University of Melbourne Friday, and in Tasmania Sunday.

Dr. Pollitt's been lecturing about laminitis for years, but his work now has the added synergy of the brumby (wild horse) research component, which in turn has been energized by some out-of-the-box thinking about domestic vs wild horses that will have all of us scratching our heads when we finally hear these lectures.

Dr. Pollitt's model foot begins with a MIMICS image, created in collaboration with Dr Simon Collins, Animal Health Trust, Newmarket, UK

There were gasps of apprehension when Dr. Pollitt stepped down as professor at the University of Queensland vet school, but the research world was pleased. Freedom from teaching would surely allow him to dedicate full time to his directorship of the Australian Equine Laminitis Research Unit, the world's leading center for laminitis research at the University of Queensland.

To everyone's surprise, something else happened. In addition to charging forward on the laminitis front with a collaboration with the Laminitis Institute at the University of Pennsylvania, he started a second research center, the brumby unit, designed to study the hooves of Australian wild horses so that he could finally come to understand how a normal foot is supposed to function.

For years, Dr Pollitt has said that his hands have been tied in laminitis research because he is trying to understand a disease mechanism in the foot without being able to compare it to the normal functioning foot because we simply don't have a good model of the normal foot.

So Pollitt and his research associate, Brian Hampson, and most recently with sidekick American veterinarian Dr. Donald Walsh of Missouri, have been trekking through the outback of Australia studying wild horses in wet, dry, rocky, sandy and even flooded terrain. They watch, they film, they tag, they camp, they bring volunteer research assistants, and they've collect data--volumes of it, none of which has been shared except in tantalizing tidbits until now.

Donald Walsh DVM of Missouri, president of the Animal Health Foundation in Pacific, Missouri, has been conducting laminitis research in Australia but rode out on brumby research expeditions with Pollitt and Hampson. Walsh has been studying wild horse feet in the USA; the Animal Health Foundation helps fund Pollitt's laminitis research. (Brumby Research Unit Photo)

Marg Richardson, a research team member of the Australian Brumby Research Unit, is one of the hosts for the lecturers this weekend and has organized the warmup tour.

She is particularly excited to be introducing Brian Hampson in his first official speaking tour. At the Australian Brumby Research Unit, Hampson is undertaking world-leading research by capturing and sedating brumbies, attaching GPS collars, tracking their movement and then recording the relevant data for herd groups. This includes what they are eating, the condition of their hooves and how much they are moving.

One of the marketing projects launched by the Australian Brumby Research Unit is making freeze-dried brumby feet available to other researchers.

Maybe, it turns out, to understand a lot about hooves we need to learn to a little bit about behavior. “Never has the saying of ‘No Foot No Horse’ been more obvious, when you see how much these horses move,” Hampson says. “We have tracked the movement of domestic horses in a variety of settings from the racing environment (to) five-acre paddocks (and) up to 10,000 acre paddocks to see the variation of movement and it has been quite staggering. Old brood mares turned out in paddocks are moving more over a 24-hour period than our elite race horses."

Dr. Pollitt's presentations will center on using computed tomography imagery to share the inside view of what happens to the hoof in laminitis and other hoof diseases, compared to normal hooves. Digital images from the CT scans, arranged in 3-D will also allow manipulation of the model to observe whatever tissue is of interest. Models will be shown for laminitis, side bone and normal feet.

A world tour is planned, of course; Dr Pollitt plans to speak at the 5th International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida, to be held November 6-8. See you there.

It sounds like Brian Hampson is ready for a world tour of his own.

I am not positive that places are still open in the lectures, but you can inquire. Please email Marg Richardson or phone (in Australia) 64 272255 or 0419 572255. Click here for a press release and links to flyers from the Equine Veterinarians Australia web site.
