SKIN & COAT HEALTHThe OPTIMUM range is enriched with a blend of zinc and omega 6. Scientific studies have shown that a blend of zinc and omega 6 delivers a healthy skin and coat. BIOAVAILABILITYAll products within the OPTIMUM Dry Dog range have been developed with high quality protein sources to ensure excellent nutrient absorption and BIOAVAILABILITY. Meaning that high levels of nutrients are absorbed by the body so that your dog can get the most out of their food and more out of life. HEALTHY DIGESTIONThe inclusion of wholegrains and beet pulp in OPTIMUM provides a natural source of fibre. This helps to control intestinal transit and maximise nutrient absorption, resulting in smaller, firmer stools. OPTIMUM DENTAL DEFENCELike humans, maintaining good oral hygiene for dogs is an important factor of good health. The specifically designed OPTIMUM dental system helps to reduce plaque build-up and helps protect teeth and gums. The mechanical action of chewing the crunchy dry kibble, in combination with the active ingredient (sodium tripolyphosphate) helps promote good oral hygiene.
