I can’t take him to the vet quite yet. I don’t exactly know what happened, but when he was playing ball in the backyard, he somehow got his bottom pad cut and now it’s bleeding all over and hanging off a little. I wrapped it, and put one of those collars around his head that prevent him from licking it. He is in his crate right now. Is there a salve I can put on it? Something I can do? Thanks!
