Dressage Hoofcare: Rob Renirie at Global Dressage Forum

3 November 2009 | Fran Jurga's Hoof Blog

A funny thing happened on the way to the Forum.

The Forum, in this case, would be the Ninth Global Dressage Forum, held last week at the Academy Bartels training center in Hooge Mierde, the Netherlands. And the funny thing was that a farrier was a speaker at this event for the first time, and no one thought that unusual at all. What's more, they paid extremely close attention to his advice.

The farrier? I can only think of a few who can hold the attention of an arena full of dressage experts, many of whom would be testing their own opinions against the farrier/speaker's.

But no one can argue with this farrier's results. Horses from many countries shod and/or trimmed by Rob Renirie have won an amazingly consistent stream of Olympic, World, and European medals for the past ten years. He jokes about it, pokes fun at his clients, but has taken care of the horses they've asked him to keep in tune with the ground.

No, Hoofcare & Lameness was not lucky enough to be in Holland for Rob's lecture, but we have friends all over the world and some of them were very helpful at this event. Astrid Appels of EuroDressage.com has written an excellent summary of Rob's presentation on her web site, and I would encourage you to go there and read the entire article (and see the photos).

While Rob is best known for his Olympic gold medalist client Anky Van Grunsven, he cares for the hooves of many of Europe's top horses and travels with the Dutch team to international events. He also works with veterinarians on a regular basis, both on sport horse injuries and special clinical cases.

Here are some key points from Rob, as passed along by Astrid. Remember, English is not Rob's native language, although he speaks it very well:

"The frog is important for the blood supply and to absorb shocks. You have to leave it as big as possible and leave the bars in. The sole is as thick on the toe as on the heel. You have to leave the toe as thick as possible."

"The coronet band determines the shape of the shoe."

(Referring to Adelinde Cornelissen's successful European Championships dressage horse) "Parzival had flat underrun heels and the wrong shoes. He is wide in front and narrow in the heel. We worked on him a few times and the horse had a tremendous recover in his feet."

Rob restated his sentiment from lectures in 2007 at the laminitis conference in Palm Beach that side clips are undesirable and can distort the wall. "They get too tight on the feet."

"Do not correct the feet, but protect the feet."

"We keep our horses as prisoners in a stable, which is not good for the blood supply."

Rob restated that his own horses are not shod and that he feels that is the best way for a horse to be, qualifying that advice for horses that don't have hoof problems and are not moved between radically different surfaces.

After the lecture, a group of attendees had a special opportunity to enter the stables of Dutch team rider Imke Schellekens-Bartels, and review the hooves of some of the horses at hand.

Note: Rob has a web site, though there's not much on it. There is some nice music and some images of his work and especially his fabulous shoeing van and some scenes from his worldwide travels. Click here to go to Rob's web site; just click on the photos at the lower left and they should begin to change.

Here Lies the Farrier...And There Goes Tam O'Shanter

by Fran Jurga | 31 October 2009 | Fran Jurga's Hoof Blog

Lichen covers this fascinating old gravestone in the Alloway kirkyard near Ayr, Scotland. Surely a farrier lies here. Was he the farrier who inspired the lines in the poem: "That every naig was ca'd a shoe on, The smith and thee gat roaring fou on"? (Tam and the smith had a drink for every shoe that was nailed on.) Or did he die earlier so it was part of this scene: "Coffins stood round like open presses / That shaw'd the dead in their last dresses /And by some devilish cantraip slight / Each in its cauld hand held a light."

Happy Halloween!

There are many farrier headstones in cemeteries around the world. Grand anvils and headstones sporting horseshoes decorate churchyards and forgotten family plots. But I think this one is suitable for Halloween!

You'll find this stone in the churchyard at Alloway, near Ayr in Scotland. Was this farrier also a pirate (note the skull and crossbones) and someone with royal ties (note the crown)?

This graveyard is not far from Closeburn, the home of the late famed farrier Edward Martin, and I must assume that Edward knew of this stone, though I don't recall him telling any stories about it--and this stone surely has a great story!

Alloway is the town of Robert Burns's birth as well as where he set his famous poem, Tam O'Shanter. This is the universal tale of a man who simply stayed too late at the pub one night, drinking with the smith (perhaps the one buried here?) and his other pals, and had to count on his good mare Meg to get him home in foul weather.

Tam was shocked to see half-dressed women from the village cavorting with the devil. But in his drunken state he called out in admiration to one attractive woman in a "cutty sark", which set them all in pursuit after him.

The poem is interpreted many ways when it comes to people's views on alcohol, witchcraft and lewd behavior. But there is never any doubt about the character of the horse involved.

Tam gives his mare Meg her head to find her way home and probably snoozed in the saddle. Passing through Alloway, he's startled awake to see the church ablaze, with witches dancing in every window as the devil plays the bagpipes and the graveyard's coffins open wide.

The Brig o'Doon, or bridge over the River Doon in Alloway. Apparently, a witch can't cross a running stream so Tam spurred his mare on. Once across, Tam O'Shanter would be safe from the witches, though he would still have to answer to his wife. But his horse would never be the same again.

I won't spoil the story for you. You can read the interpretation here. (It's a great tale!)

But let it be known that Meg the Mare takes care of her rider that night...though she spends the rest of her life as testimony that something did happen on the way home, even if it was the most elaborate and world-famous tale a husband ever made up for why he was late coming home from the pub. 

Spooky enough for Halloween, don't you think?

Halloween: The Original "Jack o'Lantern" Was a Grumpy Blacksmith with a Glowing Lump of Coal

by Fran Jurga | 31 October 2009 | Fran Jurga's Hoof Blog


So here's the way the story goes...I'll tell the short version because it's an Irish story and you know how long they can be.

There once was an Irish blacksmith named Jack. He was a miserable man, and he spent his nights in the pub trying to make everyone around him miserable, too.

One night he made a deal for one more drink, but he had no money so it had to be paid for by the Devil.

The devil demanded to be paid back, but Jack tricked the Devil. That's never a good idea. The Devil promised Jack that he'd take his soul.

When the blacksmith died, he was refused admission to heaven for all his evil, selfish deeds, and foul moods. He was sent straight to the gates of hell.

Whom do you think was waiting for Jack? 

The Devil was standing at the gates to Hell. He immediately recognized Jack as the Irish blacksmith who had cheated him. The devil crossed his arms and refused to let Jack into hell.

Where was Jack supposed to go? The Devil didn't care, but Jack had better get going. Jack pleaded for a coal from Hell's fires so he might see his way as he wandered out through the darkness.

The Devil granted his wish and squashed a glowing coal into a half-eaten turnip. He handed it to Jack with a smirk.

The grouchy old blacksmith wandered off and guess what? He wandered forevermore. He's still out there, they believe in Ireland.

It's said that Jack's piece of glowing coal in a turnip could be seen across the Irish countryside at night as he wandered aimlessly, the ultimate ghost.

And of course, as a smith, Jack would have had the skill to keep the coal ember going. He made the most of the devil's generosity.

Irish children began to imitate Jack's lantern and Irish-American children switched from turnips to pumpkins on this side of the Atlantic.

And so it is that so many of us still place glowing vegetables on our doorsteps on Halloween to scare away the haunted souls...like Jack, the grumpy, cheapskate, old blacksmith who is out there somewhere, tonight.

She Strolls Through the Horse Fair on Halloween...

by Fran Jurga | 31 October 2009 | Fran Jurga's Hoof Blog


I've been saving this picture for today. It's from a portfolio of images, mainly farriers, taken at the Smithfield Horse Market in Dublin, Ireland, one of the last urban horse sales in western Europe. The travelers bring horses and ponies and donkeys into the city the first Sunday of each month to sell or trade them. They've been doing it exactly this way, in the shadow of the Jameson's whiskey distillery, since 1665, as much as the city has tried to stop this chaotic manure-producing festivity. Dublin is one of the last cities where horses are kept within the city by private owners, many by young boys who tether them on any available greenspace.

One Dublin photographer, Teresa O'Brien, is especially taken with the farriers who skip church and show up to shoe the horses at the market before they are sold. But she only photographs their hands. I've never seen the rest of these men. Later, she moves through the crowd and her lens finds a hand on rusty hames or in this case the hand of a traveler (gypsy) matriarch's multi-ringed fingers.

Imagine this woman draped in her long dark hooded coat and leaning on her cane. She is walking among the horses on a chilly October morning. She speaks to no one. Is she buying or selling or is there something spooky going on here? Is she the ghost of horse markets past?

Click here to read a little more about and see a little more about Smithfield Horse Market.

Smithfield Horse Market and the gypsy horse fairs of Ireland and England are some of the last horse fairs. I grew up staring at a print of the painting The Horse Fair by Rosa Bonheur (above; the original painting is 16 feet long and hangs in the Metropolitan Museum of Art in New York City). It is still one of my favorite paintings because there is so much going on and the horses are so well-formed.

But if you think about it, what will go on this Sunday morning at Smithfield hasn't changed much from Bonheur's basic scene, which shows the horse market in Paris in the 1800s. Someone should document the few horse fairs that still exist. I know there are still big ones in India and Mongolia--where else are they still held?

From Sim to Mo-Cap to Slo-Mo: Have Another Look at the Horse in Motion

by Fran Jurga | 28 October 2009 | Fran Jurga's Hoof Blog

Today I hurt my eye and it made the world a different place. Depth perception was different, some things don't quite line up, and this computer screen is a little blurry so this post will be a media-rich one. I'll let the videos tell the story.

And the story is exactly what I have been experiencing: how do we look at things? You read research reports and case studies and observations on this blog all the time, but they are from the viewpoints of different original sources. Here are some examples of the sources the Hoof Blog uses.

This is a computer-generated leg model from the University of California at Davis. The model lives in a perfect world. Someone designed a limb with arbitrary (or perhaps intentional) conformation and measured the resulting tendon, ligament and muscle forces if this ideal limb was moving over a perfectly smooth, non-deforming surface.

This is what we now call "traditional" two-dimensional video analysis, often used for before-and-after shoeing and trimming evaluation.

This very brief clip is 3-D analysis. You might want to use the play button to start and stop it and see more detail.

Finally, here's high-speed video, or what you might call high-quality slow motion. This polo pony is exhibiting the same stride characteristic as the computer model at the top but wow! he is influenced by the weight and lean of his rider and the variable deformability of the field as well as, no doubt, probably some conformational traits that offset his limb alignment. This is the real world.

There are plenty of other ways to capture horses and model their movement to study and analyze them; the idea here is that when you read an article, the authors may be extrapolating data from a computer model or from subjective observation with no data collection. You have to read the fine print and always take into consideration how a study was conducted and how many horses were in a study.

Does the moving horse interest you? Cornell University will host a veritable festival of motion capture, slo-mo and gait analysis at the 26th Farriers Conference November 14-15 in Ithaca, New York at the College of Veterinary Medicine. The early registration deadline is Friday so get organized and save $50 over the on-site fees.

Speakers at Cornell include farriers Scott Lampert of OnTrack Equine in Minnesota and Mark Aikens from Anglia Equine in England, both of whom are leaders in using videography in analyzing how shoeing and trimming effect horses' movement. Dr. Jeremy Rawlinson of Cornell will demonstrate the use of Cornell's force plate system and de-mystify the concept of ground reaction forces.

Hoofcare & Lameness is thrilled to be a part of this event. For a full schedule and list of speakers, and to register online, click here or go directly to http://www.vet.cornell.edu/education/conferences/farriers/

A Tribute to Bracy Clark: It's the 200th Anniversary of Natural Hoofcare

by Fran Jurga | 26 October 2009 | Fran Jurga's Hoof Blog

What year is it?

Patrick Ryan was, according to this slip of paper, a doctor (?) of horseshoeing in Baltimore, Maryland in the late 1800s.

You might have to double-click on the image to read the fine print, but across the top of the bill head, Mr Ryan promises "Horses Shod According to the Natural Formation of the Hoof. Satisfaction Guaranteed."

There's nothing new about the new school of thought on natural hoofcare. In the 1800s, a legion of learned professors and prickly posers preached any number of plausible and implausible theories about the so-called natural function of the hoof, as they interpreted it to be at that time. Most of the theories involved employing the frog by using a thin shoe or even a three-quarter shoe that exposed the heels and base of the frog to concussion, in the belief that that would stimulate the pumping action of the frog.

Professor Bracy Clark in England was the leading proponent of truly natural hoofcare, and his writings are quite interesting and worth a read. Just the reverse of Ryan in Baltimore, he was a veterinary surgeon--in the earliest days of the profession--who left academia behind and chose to shoe horses and study the hoof for the rest of his life.

Professor Clark enjoyed a renaissance about ten years ago when Dr Hiltrud Strasser chose selections from his vast body of writings to defend some of her theories. What many people missed was that he was a highly respected veterinarian and actually has a very broad body of writing on the anatomy and function of the foot and its diseases, far beyond simply expressing displeasure with shoes. In fact, he tried tirelessly to invent horseshoes that would work in harmony with the natural function of the foot and not stifle it.

The author/historian Major-General Sir Frederick Smith writes of Bracy Clark, "No writer in the profession before or since [his] day has brought to bear such a degree of scholarship."

In fact, Bracy Clark's first writings were exactly 200 years ago, in 1809. So let's tip our caps to him today. I recently learned that a packet containing Professor Clark's 1809 manuscript sold at auction for 3,130 British pounds--that's roughly $5,000 for some very frail old farrier papers.

Bracy Clark's forge near London's Regent's Park

To quote from an article by Ian McKay in the October 2009 edition of Book Dealer:

...This little collection opened with an illustrated 1809 account of A Series of Original Experiments on the Foot of the Living Horse. On the back of the frontispiece to this main work is a tipped-in prospectus in which Clark explains that he plans to publish his discoveries from time to time but ‘…must depend upon the intelligent and opulent for support in reimbursing the expenses…’, while bound in at the end is a single explanatory leaf, titled A New Exposition of the Horses Hoof, that refer to a pasteboard model of that equine extremity.

Other tracts in this little volume included Essays… on …the Nature and Cure of the Split-Hoof, Vulgarly Termed Sand-Crack and …the Causes and Cure of Running Frush in Horses’ Feet, both of which are dated 1818, plus another of 1822 …on the Canker and Corns of Horses’ Feet.

Another of the seven items that make up the collection is the advertisement ...., in which Bracy Clark announces that he has retired from all work with horses, ‘except what relates to the feet only’, and has opened a "…forge, in the Edgeware Road, near the Paddington Turnpike, for shoeing Saddle Horses, more especially, upon a New Plan, which admits the natural expansion of his Foot, and is more durable than the common shoe."

I got out my magnifying glass and was able to read some of the tiny print in Professor Clark's ad. I could read that he added at the bottom "Shoes made and sent (for ready money) to any part of the kingdom. No rasping off the natural rind of the hoof, no frog scalping--or notching of the heels allowed. A lecture on shoeing and the nature of the foot is delivered by the inventor the first Monday or every month at 12 o'clock. Admission 5 shillings." He would teach "professional characters" how to shoe according to his method for one price, and the sons of shoeing smiths for a reduced rate.

And now the big question: who bought these precious historic manuscripts? And what will he or she do with them?



Click here for original document: Bracy Clark Expansion Shoe -

Here's Bracy Clark's treatise on his tablet expansion shoe; the images are on the last pages. You can click on "full screen" at top right of the image box to read it easily and print it. The pages may load slowly, depending on the speed of your connection. I hope you will read it and realize how articulate this man was in describing the foot and his theory of hoof expansion. Read the part where he says that this shoe is his gift to horses, and that he is not patenting it so that more horses can benefit from it. In that sense, reading this reminds me of the Steward Clog.

What would I give to go back in time and head to Regent's Park for one of his Monday lunchtime lectures? This fellow's writings are worth a read, a re-read and many good long discussions to see where and how we've changed the way we look at the hoof's function. What would he say if he showed up today?
