Hill's Prescription Diet

Targeted Clinical Nutrition for Every Health Need with Hill’s Prescription Diet

When your dog or cat is diagnosed with a medical condition, proper nutrition becomes a vital part of their treatment plan. Developed by a global team of veterinarians, PhD nutritionists, and food scientists, Hill’s Prescription Diet offers clinically proven therapeutic nutrition designed to manage specific diseases, slow condition progression, and improve your pet's quality of life. At Petstock, we carry the full range of Hill’s Prescription Diet wet and dry formulas to ensure your pet receives the precise, vet-recommended diet they need to thrive.

Clinically Formulated for Specialized Health Management

Hill’s Prescription Diet covers a broad spectrum of medical needs, providing targeted nutrient profiles to support your pet's specific health journey:

• Digestive Support: Fast-acting formulas like Hill’s i/d and Gastrointestinal Biome feature proprietary ActivBiome+ ingredient technology to rapidly nourish beneficial gut microbes, soothe upset stomachs, and improve stool quality.

• Urinary Care: Clinically tested diets such as Hill’s c/d Multicare and s/d are formulated to dissolve struvite stones, control key minerals (magnesium, calcium, and phosphorus) to prevent crystal formation, and support long-term bladder health.

• Weight & Mobility Care: Synergistic diets such as Hill’s Metabolic + Mobility help pets lose excess weight while reducing joint pain—combining weight management technology with high levels of Omega-3 fatty acids (EPA) to preserve lean muscle and enhance joint flexibility.

• Food & Skin Sensitivities: Hypoallergenic and hydrolysed protein diets like Hill’s z/d and d/d are formulated with single animal protein sources or broken-down proteins to prevent adverse food reactions and eliminate food-related skin irritation and digestive upset.

• Dental Health: Specially engineered kibble technology in Hill’s t/d acts like a toothbrush as your pet chews, mechanically scrubbing away plaque, tartar, and bacteria to support oral hygiene and freshen breath.

• Kidney Care: Low-phosphorus and controlled high-quality protein recipes, including Hill’s k/d, help reduce the workload on failing kidneys, support muscle mass maintenance, and slow the progression of Chronic Kidney Disease (CKD).

Frequently Asked Questions About Hill’s Prescription Diet

Do I need a veterinarian’s prescription or advice to buy Hill’s Prescription Diet?
Yes. Hill’s Prescription Diet products are therapeutic foods formulated to manage specific health conditions and contain precise mineral and nutrient levels. Feeding these diets without veterinary guidance can mask underlying health issues or provide improper nutrient balances. Always consult your vet before starting or changing a therapeutic diet. If you need updated advice or a recommendation, our Petstock Vets are here to help—visit our Vet Services page to learn more or book an appointment.

Can I mix Hill’s Prescription Diet wet canned food with dry kibble?
Yes, provided you are mixing wet and dry versions within the same Hill’s Prescription Diet formula (for example, Hill’s c/d wet stew mixed with Hill’s c/d dry kibble). Combining wet and dry food is a great way to increase hydration, enhance mealtime palatability, and give your pet variety while maintaining their strict clinical diet.

How quickly does Hill’s Prescription Diet start working?
Results depend on the formula and condition. For instance, Hill’s Gastrointestinal Biome can improve stool quality in as little as 24 hours, and Hill’s c/d Multicare is clinically proven to dissolve struvite stones in as little as 7 days (average 27 days). Other conditions, such as mobility improvement or kidney support, may take a few weeks to show full clinical benefits.

How do I transition my pet to Hill’s Prescription Diet food?
Because pets with clinical conditions can be sensitive to sudden dietary changes, you should transition them gradually over 7 days. Mix increasing amounts of the new Hill’s Prescription Diet with decreasing amounts of their current food until they are eating 100% of the new diet by day 7.
