Pearl very itchy almost all the time--it's gotten increasingly bad as she's gotten older. The only thing that seems to really help it is prednisone, and I hate to give her that on a routine basis. She was on Wellness fish and sweet potatoe diet for awhile, and that didn't dent it. Every so often I see a post somewhere that someone has tried allergy testing and shots for their dog, and it helped considerably. My vet doesn't seem very excited about them. Any one out there tried them for their dog? What kind of results did you have?
