Ah, the food, Moira does best on fish based grain free. Canidae GF Salmon worked best for her when she had skin issues before the fleas. The antihistamine - her vet had just come from a dog allergy seminar when she presented with allergies late last Summer. He said research shows that chlorotrimton works better for dogs than Benedryl. I got hers from Drs Smith & Fosters for $5 for 100.
