Our 8 year old English bulldog has been on prednisone and multiple antibiotics in the past five years. We have had allergy testing in the past with environmental allergies. We had to stop allergy shots due to the expense. We have tried white fish and sweet potato and chicken, sweet potato, and pumpkin...all grain free. He is up itching all night off and on and also during the day. I feel so bad for him. In the past, vets have had us try Benadryl and now chlorpheniramine. Still no relief. Can anyone suggest ANYTHING I could possibly do for my poor baby?
