Our doctors will recommend general to specific dietetic changes, if needed, to provide your pet with the optimal nutritional requirements, either for weight management or in support of specific medical diseases or for support with ongoing medical issues. For weight control it may be as simple as reducing the amount and frequency of feeding or as comprehensive as an appetite suppression medication with specific feeding instructions. Hills Science Diet is a leading manufacturer of Prescription Diet foods. These foods are sold by prescription only. If you think one of the prescription diets may be beneficial to your pet, please ask one of our veterinarians for further information or visit Hills Prescription Official Website.
