Rookie is just over one year old. when i first got him he was constantly biting his feet to the point that he was pulling the hair out. that was when he was about 8-10 weeks old. i took him to the vet and because it was so severe he started him on prednisone. after going to a vet specialist, we changed his food to human grade (merrick) and tried to keep him off the grass as much as possible (a puppy off the grass...sad). we also changed him from prednisone to atopica. over the winter he hasn't scratched at all and we weened him off the atopica. now it has started all over again. licking and biting his feet. i took him back to the vet and they preformed an allergy test which came back negative. she said that it could be because he is so young that he may infact have allergies. now we have him back taking one atopica every other day, hydroxyzine three times a day and fish oil capsule once a day. poor guy. i feel so bad for him because he is uncomfortable. does anyone have any ideas?
