Pet's info: Dog | American Pit Bull Terrier | Male | unneutered | 2 years and 4 months old | 80 lbs
My dog has bumps and knots only on his back. So i dont think its from being outside, it would be on his paws and legs too, right?. I think its bites. He is on Advantage multi so its shouldnt be fleas. I bathe him every other day with allergy shampoo and that doesnt seem to help. What else could it be? They bust and bleed. He doesnt seem to be in pain and doesnt scratch. But i dont want him to experience it anymore

This sounds quite uncomfortable for Sly! He could be experiencing a skin infection from underlying allergies, ringworm or mange causing these issues. I'm glad to hear that he is on Advantage Multi because this makes a flea allergy seem less likely. However, many dogs are allergic to their foods or a host of environmental factors. At this point, your best bet is to take him to the vet. The vet may need to perform fungal cultures (to rule out ringworm), skin scrapings (to rule out the mites causing mange), or skin cytology (to determine if bacteria is present in these lesions). From there, the vet will be able to prescribe medications (i.e. antibiotics, antifungals, anti-itch, etc.) to try to help Sly. Bathing him every other day could dry out his coat and remove normally present oils, which can make matters worse. I only recommend bathing this frequently when using certain prescription-based medicated shampoos. Under normal circumstances, try not to bathe him more than every 2-3 weeks. You can use a damp cloth to wipe Sly down each time he comes inside to try to remove any pollens clinging to his coat. I hope that all goes well!
