my springer spaniel puppy is constantly itchy and gnaws at herself because of it. when we got her she had lice so we put frontline spot-on on her and that seemed to do the trick for a week or two but ever since she gnaws herself more and more. she is due another dose in a few days if i give it to her on a monthly basis. i checked the spots where she is especially itchy but can't find much except a few pieces of brown dandruff, or at least i think it's dandruff. some one told me that it might be a puppy version of cradle cap. never heard of it before but could it be something along those lines and if yes, what can i do to ease her discomfort? i feed her pedigree dry puppy food and her coat is nice and glossy so i can only assume that the food agrees with her. any help will be appreciated.
