Prescription diets are specially formulated foods designed to manage specific health conditions in pets. These diets are often recommended by veterinarians to address issues such as obesity, kidney disease, or food allergies. They contain precise nutrients and ingredients tailored to support the pet's health needs. These diets are not available over-the-counter and require a prescription from a veterinarian. This ensures that the pet receives the appropriate diet based on their individual health status. Common brands of prescription diets include Hill's Prescription Diet, Royal Canin Veterinary Diet, and Purina Pro Plan Veterinary Diets.
