Chewing,Scratching, digging till he bleads?
I have a 1 year old St. Bernard and he is constantly biting himself, scratching himself, and digging at his skin. I know he does not have fleas. I can not get him to stop this. He bites scratches digs until he wears the to layer of skin off and it is bloody. Not like gushing blood but like a rug burn then it scabs over. I have no idea what it could be? Hot spots? Allergies? I really need help. I'm getting so frustrated because he has these scabs all over his rump? Does anyone have any suggestions on what they think. Or a situation like this. Any suggestions how to treat it too? I'm desperate!
