Urinary crystals have a number of causes, but when they are caused by an irreversible metabolic disorder in the excretion of uric acid, the problem needs to be treated by a long-term change to a special diet. Royal Canin Urinary U/C low purine is designed for dogs age 1+ to help to maintain health and prevent relapse in dogs with metabolic disorders causing urinary stones. The recipe includes proteins with a low purine content and also helps to prevent the build-up of cysteine stones. Fluid loss through the skin can be reduced by feeding a food with a high biotine content, with niacin, pantothenic acid as well as zinc and linoleic acid. A synergistic antioxidant complex can protect cells against malevolent metabolites. Recommended for (indications): To work with leishmaniasis therapy with the use of xanthine oxidase inhibitors (e.g. allopurinol) Food to preserve good health in adult dogs of certain breeds predisposed to the formation of metabolic-related urinary stones (e.g. dalmatian) Prevention of relapse of metabolism-related urinary stones (urate, xanthine, cystine) Not recommended for (contraindications): Parallel treatment with drugs that increase urine acidity Lactating bitches, pregnant bitches or puppies Key benefits: Urate prevention: Selected proteins with low purine content (for example, wheat flour, egg) in conjunction with an alkaline urine pH can help reduce the risk of Uratharnsteinen. Cystine prevention: The composition of URINARY U/C helps prevent the formation of urinary stones. Skin barrier: Very high levels of biotin, niacin and pantothenic acid in combination with zinc and linoleic acid help to reduce fluid loss through the skin and strengthen the barrier effect. Antioxidant protection: A synergistic antioxidant combination (vitamin E, vitamin C, taurine, lutein) can protect cells from attacks from aggressive metabolic products. Further information: Owners should feed Urinary U/C exclusively, to ensure maximum effectiveness. Duration of treatment: Urate stones: min. 6 months. For permanent metabolic disorders, this food can be fed for the dogâs lifespan. Cystine urinary stones: feed for up to one year. Ensure your dog receives regular therapy reviews to revise feeding guidelines.
