I have a question about my mini's hoof. He has foundered in his past and still has some inflammation in his hoof wall. If you look at his hoof, on the bottom, you can see that the hoof wall ends, and it is black underneath (almost looks like the hoof is raised). Also there is some pink on the sole of the hoof near the wall that is NOT shown in the picture. He last had his feet trimmed two weeks ago. He is not sore and is standing and acting fine. Does this look normal or is it something to ask my vet or farrier about? Thanks guys!
