And, yes, I know this horse is due for a trim!
That’s the whole point of my thread, that she gets much more comfortable on gravel late in the trim cycle.
These photos are 8 weeks from the last trim. For the first six weeks, horse was ridden walk/trot on sand/gravel with Renegade boots on the front, and barefoot in the hogfuel arena, with no problems. For the past two weeks, horse was ridden barefoot walk/trot on all surfaces, with no problems. I stopped using the boots because they don’t fit after her hooves grow out. I don’t know how long after her last trim it would have taken for her to be fine barefoot on the sand/gravel, since I didn’t try it in any consistent way until she outgrew her boots.
When I started barefoot two weeks ago, I think it took a few days for her to get completely comfortable, but I wasn’t keeping careful notes on this.
Background:
We’ve been dealing with two specific issues in the past couple of years. Both times, I’ve called in a good vet who is also a trained farrier, to consult with my own farrier. Both times the results have been good.
First, about a year and a half ago: dealing with persistent mechanical hoof/wall separation on the quarters of all four feet, aggravated by a hot dry summer, and a longish gap between trims. Pebbles were going up the white line and making the problem worse. Vet recommended rather aggressive resectioning, cutting away all the loose hoof wall, several inches up in some cases. This was scary ugly to look at, but did not seem to bother the horse. The new wall grew in clean and tight. There was never any white line disease or laminitis involved. After her flares were resolved, I started using the Renegade boots.
Second, a few months ago: consulted vet again on horse’s tendency to pronate with rear feet, that is land on the outside of her hooves. This causes hoof to wear and grow unevenly, and this imbalance then makes the pronation worse. The stress of the twist on landing has been causing windpuffs in her ankles, and sometimes we think a bit of reluctance to canter under saddle when her feet are particularly unbalanced.
Vet did a tight trim on the rear feet, focusing on pulling back the toe and the heel. Farrier copied his trim four weeks later (last trim). This was a slightly “aggressive” trim and did leave her a bit tentative behind on gravel for the first week. When I look at the feet now, they are a bit asymmetric still. The outer half of the foot is wider than the inner half. But the wear pattern is more even than in the past.
I also see, looking at the these photos, that there is not really any weight-bearing wall at the quarters. The sole is more concave than the photos show, and the outer edge of the sole has hardened up into a weight-bearing edge.
My big worry, given her history, is about the fraying of the white line and the start of flare, with pebbles going up the white line.
Her front toes, though, which wear snubbed back, are much tighter. So maybe the solution really would be to keep a file on hand, and rasp the quarters in the same manner, as one of the posters above said a 45 degree angle.
