My sheltie gets red, scabby spots all over his belly and even on his legs and sometimes back. They're very itchy, and we've used hot spot spray, medicated shampoo, etc. Went to the vet about a year ago and antibiotics cleared the problem up but then they came back. I suspect it's a flea allergy because as far as I can remember, he doesn't get the spots in the winter. For those of you whose shelties have flea allergies, how have they been treated?
