He doesn't itch his tail but he's stopped wagging his tail entirely. He tucks his tail all the way in, I've sprayed some doggy cortizone on the wound, but it doesn't seem to heal. My dog still sits on his tail so I don't think it's hurting too badly, but I'm worried that the wound isn't healing.

Bring him to the vet. that is serious, it could get infected and need to be amputated if it is not treated correctly. You can try taking the dog to the vet, so s/he can put proper bandaging on it and disinfectant dog bodys take a little more time then we do but see if he keeps bitting his tell if he is or isnt give it some air to scab then but vaslonie on his tell it work for dog who chue or scharch there ears and flys dont get on them so they cant chue on the dog s Try some neosporin or they make some first aid spray for animals at the pet store. I've used neosporin on almost all my pets, usually works for minor cuts and stuff. Call the vet and ask him what he thinks describe it to him or her and if you're tight for money and can't take him to the vet maybe he'll give you a remedy over the phone. Also Iodine is a good for cuts
