Hey guys my bully has jsut recently been getting bumps allllll over his back that end up getting crusty and scabby and because of that has huge bald spots on his back. I’ve been giving him Benadryl and rubbing a prescribed cream from the vet on his back. I’ve also recently been rubbing coconut oil on his back. The vet had said it’s alergies to something so I switched his food from chicken to beef to see if it would help. Is there anything else I can do?
