This complete hypoallergenic veterinary diet helps nutritionally manage food allergies in dogs of all ages, including puppies. PURINAPRO PLANVETERINARY DIETS Canine HA Hypoallergenic is also useful for dogs with severe bowel conditions such as Inflammatory Bowel Disease as it is particularly highly digestible. PURINAPRO PLANVETERINARY DIETS Canine HA Hypoallergenic is a true hypoallergenic diet formulated with protein that has been broken down (hydrolysed) into very tiny components that are too small to provoke an allergic response, and a purified carbohydrate source. Hydrolysed diets are recognised as the best type of food to use during an 'elimination diet trial' when trying to diagnose (or rule out) food allergy. During such a trial it is important that your dog is fed no other food or treats. Benefits: - Single hydrolysed protein broken down into tiny components too small to cause any allergic reaction - Purified carbohydrates to reduce the risk of an allergic reaction occurring - Added omega-3 fatty acids to help maximise the natural anti-inflammatory process.
