To maintain and maximize your pet's specific health needs and comfort Circle Veterinary Clinic maintains a supply, or can readily order, prescription diets from each of the three main providers of diets. The diets can also be purchased on our online pharmacy and delivered to your door here in the Wilmington, DE area or anywhere. The companies providing these diets are the Hill's Company, Royal Canin, and the Purina Company. Prescription diets are extremely helpful in many acute and chronic medical problems cats and dogs may experience including, but not limited to digestive upsets or food sensitivities, bladder inflammation (especially in cats) or bladder stones, skin problems, and even arthritis. There are diets to reduce weight and maintain good body condition and to keep the teeth and gums healthy with specific dental formulations. With regard to food allergies and skin problems these diets have proven superior to pet store brands due to the purity of their ingredients and processing. Please call if you have any questions about prescription diets.
