My rabbit has pretty bad sore hocks and also poopy butt because of some birth defects, anyways he gets poop stuck on him a lot and now there is some caked and hardened on the bottom of his feet. I bathe him a few times a week but it doesnt seem to soften at all. I also don’t want to try to pull it off of him because I am afraid of hurting his sore hocks. Do you think I could take him to the vet and they could get it off? Or is there something I could try at home to avoid a big vet bill for something simple? Thanks!
