hi, my sisters staffy had a flea allergy which caused her to itch and scratch alot, she has been treated with comfortis so has NO fleas nomore. She also has a cortizone (sp) injection when needed from the vet this stops her scratching but i have heard of medicated shampoos that can help with this sort of skin problem. If anyone out there knows of a great product they can recommend and let me know that would be great TIA
