ROYAL CANIN® Anallergenic Dry Dog Food 3kg is a dietetic dry kibble that has been specially developed for dogs with extreme food sensitivities or allergies. It presents an excellent choice for use as an exclusion diet. The recipe uses a low molecular weight protein source (peptides) that can significantly reduce allergic reactions to foodstuffs. It also includes a special synergistic antioxidant complex to help to neutralize free radicals, plus a patented nutrient complex to boost the skin’s barrier function. Royal Canin pays close attention to avoiding contact with any kind of allergens during the manufacturing process. Your dog’s skin and digestive tract are two of its most sensitive organs and they can come into contact with many different substances. Food allergies and intolerances are common in dogs and allergy symptoms vary in severity. These can occur at any time in their life, when their immune system reacts to an otherwise harmless substance of animal or vegetable origin in its environment.
