Prescription diets are therapeutic foods formulated to manage or treat specific medical conditions in pets. Unlike over-the-counter foods, they are developed through clinical research and must meet strict nutritional standards. RVC recommends and stocks prescription diets for various conditions.

Key Points

  • Prescription diets are formulated to manage specific diseases
  • They are different from regular pet food and over-the-counter 'specialty' diets
  • Available for kidney disease, urinary issues, diabetes, food allergies, liver disease, and more
  • Must be used under veterinary supervision
  • Many are available only through veterinary clinics
  • Switching diets should be done gradually over 7-10 days

How Prescription Diets Work

Prescription diets modify nutrient levels to support pets with specific diseases. Kidney diets: reduced phosphorus and protein to ease kidney workload, increased omega-3 fatty acids to reduce inflammation. Urinary diets: controlled minerals and pH to dissolve or prevent stones. GI diets: highly digestible proteins, prebiotic fiber, and low fat for sensitive stomachs. Hypoallergenic diets: hydrolyzed proteins or novel proteins for food allergies. Weight loss diets: reduced calories with increased fiber for satiety.

Why Veterinary Supervision Matters

Prescription diets are formulated for specific conditions and may not be appropriate for healthy pets or pets with different conditions. For example, kidney diets are low in protein and phosphorus — fine for kidney disease but inappropriate for growing puppies. Weight loss diets are reduced calorie — not suitable for underweight pets. Some diets interact with medications. Your vet ensures the diet matches your pet's diagnosis, stage of disease, and overall health. Regular monitoring ensures the diet is working.

Transitioning to Prescription Diets

Switch gradually over 7-10 days to avoid digestive upset: Days 1-2: 75% old food, 25% new. Days 3-4: 50/50. Days 5-6: 25% old, 75% new. Days 7-10: 100% new. Some pets resist new foods — warming the food slightly, adding a small amount of low-sodium broth, or mixing with a small amount of the old food can help. For very fussy pets, your vet may recommend specific palatable options or appetite stimulants. Consistency is key — don't give up after one refusal.

When to See a Vet Immediately

  • Pet has been diagnosed with a condition requiring a prescription diet
  • Pet refuses to eat the prescribed diet
  • Questions about which diet is right for your pet's condition
  • Concerned about cost or availability of prescription diets
  • Pet has multiple conditions requiring different diets
  • Need guidance on feeding amounts and schedule
