Hill's Prescription Diet Canine z/d Low Allergen

Dogs that have food allergy or intolerance, also called adverse reactions to food, typically are having an abnormal response to the protein in the food. Prescription Diet Canine z/d Low Allergen has been exclusively formulated by veterinarians with Hill's Hydrolyzed Protein System, a process that eliminates intact animal proteins and significantly reduces the possibility of an adverse reaction to food. Reactions usually occur as a result of beef, dairy products and wheat.
