The issue for my horse is the swing from hard, frozen, pitted ground to sucking mud, and back again. Winter here is hard for that.
Farrier advised diligence with the durasole. Tough to tell if it helped this season. Currently debating if I should radiograph her now, coming out of a winter of abscessing, or if I should wait until fall. I think leaning sooner rather than later.
We’ve been doing this for two winters now, and I thought awfully hard about radiographing her last spring. Was very hopeful the farrier’s suggestions would solve the problem.
For your horse, don’t wait another winter to get the vet involved. Radiograph the feet and see what’s going on in there. The answer might be tweeking the trim, or adding shoes, or perhaps you’ll find something more serious. But until you LOOK, you’re really flying blind.
