ROYAL CANIN Dental is specifically formulated to help support and manage oral hygiene in medium and large breed dogs. This formula helps to reduce the formation and build-up of tartar. The shape and size of the kibble support grasping of the food, as well as tooth penetration into it. This helps to create a brushing effect, which helps in reducing the accumulation of plaque and tartar. This diet is formulated with high quality nutrients to help support and maintain healthy bones and joints. Please consult with your veterinarian to determine the most appropriate diet for your pet. Transitioning your pet from one diet to another should be a smooth and gradual process over a 7–10-day period. Please ensure you follow the correct rationing amount.
