I need help. Our 2 year old male bully will not let us clean his tail. He's had several infections. We take him to the vet. They clean his tail fine. Put him on antibiotics. Then he's fine for about a week. We got him at 8 months and was abused as a puppy so growls and bites when we try to clean his pocket. This is my 4th bulldog so I know how to clean the tail and have never had problems with my other dogs. I want him healthy and am also tired of paying the vet and the smell. Any tips would be appreciated.
