Nazira, does your horse have laminitis? I’d never heard of clogs so I googled them and found this article: http://www.thehorse.com/articles/26368/clogs-to-treat-laminitis
Thank you for mentioning them! That old cliche about you never stop learning about horses is true. My farrier and I are going to have a chat. Boo is prone to thrush in one front hoof, and I do have to be diligent about applying medication every time I clean her feet. But the basic idea makes sense–that wood absorbs more impact with each stride than iron shoes do.
