If it's not too bad and not infected with a sore, you may be able to just put fleece down and it will slowly get better. I had the same problem with one of my buns, but he had an infected sore, so I put a gob of antibiotic ointement(non-pain reliever kind) and a gauze pad over it, then I vet wrapped the foot, luckily he mostly left it alone and didn't try to chew it off. I've heard of people using A&D oinment for sore hocks on the back feet, and also using baby socks and using a little vet wrap to keep them on, but that was on the back feet. I don't know how well a baby sock would work on the front foot, if it would stay on or not. If you decide to use vet wrap, you have to cut a strip about 1-2 in. wide and when you wrap don't wrap too tight that it cuts off circulation, but snug enough that it doesn't fall off.
