My dog has a small sore on his ear, i cant seem to get it to heal, plus he shakes his head and it reopens and blood is sprayed everywhere, what can i do to make it stop bleeding and heal?

Liquid skin...it burns, so be careful, but I've used it on my dogs ear, cause while playing with our other dog, he got bitten by her sharp puppy teeth & it was the only thing that kept it from reopening long enough to heal...he didn't like it, but I wasn't enjoying the blood on my furniture from him rubbing it open

Did you take advice from vet? It will be more helpful if you take him to vet before it gets serious.
