Our bullterrier is going to be 3 in November 2010, he is white and not a lover of the sun, he is very active and sleeps inside the house, however he seems to bite and scratch himeself till there is no hair left only on certain parts of his body, (his sides, and the top of his back where his tail starts, I cream him with antibiotics but it just keeps coming back, it looks very irratting and ugly what do I do?

Who suggested the antibiotics, the vet ? If not, and it is your own idea, you had better take your dog to the vet.

Tick

Has he been treated for fleas or mange? Could be a food allergy as well. Does he lick his paws a lot or scratch at his face? A lot of dogs are allergic to grains. If he is eating commercial dog food,t here tends to be a lot of grains and fillers that dogs develop allergies to over time.

I am with Tick here, who's idea was it for the antibiotics, and was it prescribes specifically for the skin irritation? Are you bathing him at all? If so what product are you using?

He really needs to be seen by a vet so he can do some skin scrapings to try and figure out the problem.

It could be allergies, an infection, or even could be a form of mange.
