The arrows are pointing out where weight bearing is before and after the trim. During laminitis rehab a smaller than normal palmar angle may be required (2-3 degrees rather than around 5 degrees for a healthy horse) to reduce pressure under the tip of the pedal bone, therefore a hairline angle of around 25 degrees (as shown here) may be a reasonable aim. When I tried for those angles doing my own barefoot trimming, my horses had scratches all winter because their heels were down in the mud all the time. She and her husband John keep a small herd of their own equine in SW Florida and continue to offer consults for horses in need. heels, and at that point, it inflicts at an acute angle and extends under the foot in a dorsal axial direction to form the bars.

The shoe should extend behind heels to sit approximately below the coronary band. Jaime Jackson, a former farrier, was the pioneer of barefoot hoofcare in America, and is the author of the much acclaimed books, "The Natural Horse," "Horse Owners Guide to Natural Hoof Care," "Paddock Paradise," and many other books and videos. The longer I’m looking at & measuring feet, the more reluctant I am to accept that a migrated toe creates forces on the heel pulling it forward. My belief is that we can correct that, but it’s going to take time and effort.”, “You’re trimming the foot to change the inside of the horse,” said Bowker.

Your bevel will be stronger on a thick walled foot, less pronounced on a thin walled foot, but the end result should be the same. The decreased thickness of the hoof wall at the heels allows for flexibility and ex-pansion of the hoof capsule. I have lowered her heels and put the frog on the ground. Keep in mind the hind hoofs tend to naturally be more spade shaped. In figure 11, if you lowered the heels in a straight plane from toe to heel (red line), it would cause you to excessively thin the already too-thin sole at the toe.Trimming or shoeing on this plane would also perpetuate the rotated hoof capsule.

I have been experimenting with how to trim her frogs. Underrun heels are mostly the result of loss of function when shoes are applied, particularly the raising of the frog off the ground. In the shod horse the hoof angle decreases by a mean of 3.5 degrees in an 8 week period. The horse needs heels and bars to support the back of the hoof as the weight of the horse lands on those heels with every step. Ideally, the frog’s central sulcus is shallow and broad. Primary cases of contracted heels result from incorrect trimming, overgrown hoofs, or unbalanced feet with either long toes or low heels. Horse B has heels that are noticeably high.

Although the farrier trims the hoof wall to its ideal length when the shoe is put on, the hoof itself will be growing beyond its ideal from that moment on. So if the heels of the hoof have been repeatedly trimmed back and down to the widest part of the frog they are on their way to being non-existent. “The general guideline for the industry in balancing the hoof is approximately 50:50 (toe:heel), meaning that half of the foot is in front of a perpendicular line dropped from the center of rotation of P2 (short pastern) bone, with the other half being behind this same line,” he said. He compares his findings in cadaver limbs to what he sees in live client horses, their radiographs, photographs, and the like, and tries to help owners understand what the inside looks like in different situations.

After retiring from MSU, Bowker has continued his research studies with other veterinarians, farriers, and trimmers from the U.S. and other countries, particularly Australia and Sweden.
