I have a Jack Russell with severe allergies. I had the bloodwork done and have isolated all the food problems. He is more allergic to grass than anything and this time of year he chews his feet raw when he gets out in the yard. I just had him to the vet a week ago after using up my prednisone. I really did not like giving it to him but it was the only thing to stop the itching and chewing behavior. I started him on a new drug called Atopica which I have read has rave reviews for skin allergies. I also use a ketoconizole shampoo and leave on lotion. That helps alot. He gets a couple different fidonutrient food supplements with amino acids and oils. Also gets pet dophilis which is a digestive aid to help his immune system fight the bad bacteria. Its trial and error with allergies. The grass kills him but so far, after a week I see promise. He also gets benedryl three times a day. In a month she wants a liver enzyme to make sure he's not reacting. If you are unsure of the drugs, start with the keto shampoo.
