Just like us, what a dog eats at each stage of life has a powerful effect on their growth, strength and total well-being. Thats why OPTIMUM products provide expertly tailored nutrition for dogs of every life stage or life style. Every product in the OPTIMUM Dry Dog range has been developed with high quality protein sources to ensure excellent nutrient absorption and BIOAVAILABILITY. This means that high levels of nutrients are absorbed by their body so that your dog can get the most out of their food and more out of life. OPTIMUM Adult Large/Giant Breeds has been formulated with high levels of chicken, a natural source of glucosamine. Glucosamine contains the nutritional building blocks for cartilage which helps maintain joint health, which is particularly important for larger breeds.TYPICAL COMPOSITIONProtein, Crude 24.0% Fat, Crude 10.0% Moisture 9.0% Calcium 0.80% Phosphorus 0.80% Linoleic Acid (Omega 6) 2.50% Zinc 450mg/kg Vitamin E 200 IU/kg Vitamin C 75mg/kg Glucosamine (Min.) 30mg/kgIngredientsACTIVEINGREDIENTSN/ACONTAINSN/AFLAVOURwith chicken, vegetables & riceINGREDIENTSSorghum and/or rice and/or wheat; poultry and poultry by-products; barley and/or corn; chicken digest; beet pulp; vegetables; vegetable oil; salt; minerals (potassium chloride, zinc sulphate, ferrous sulphate, copper sulphate, potassium iodide and selenium); inulin; sodium tripolyphosphate; vitamins (A, B1, B2, B3, B5, B6, B9, B12, C, D, E and choline) and antioxidants.
