What does the inner hoof wall of a horses hoof do?

soft tissue and muscle. i think.... The outside wall of a hoof is keratin--same as fingernails.

A horses hoof is like a human's fingernail. It is made up of calcium. The horse has another "hoof" inside of the outer layer which is sensitive. If it gets infected, it may mean death to the horse....

It is the foot

Before I answer your question, I have to tell you that you shouldn't be doing this yourself if you have no experience with it. Before you attempt to shoe a horse, you should have seen a farrier doing...

Yes (other person) Nope. I talked to a farrier and she said that color doesn't seem to make any difference. Breed, however does.
