Okay my 16 year old mutt has a hole in his head (we have no idea what happened) and his head and left eye are swollen and his eye is oozing puss. What can we do? We've put a bandage over the hole along with some neosporin and we keep cleaning the eye. My mom will be taking him to the vet tomorrow if it doesn't look any better. I'll try and get a couple of pics of it. Thanks in advance!
