Prescription & Vet Diet Food

Targeted Clinical Nutrition for Your Pet’s Unique Health Needs

When your pet is diagnosed with a specific medical condition, their daily diet becomes a fundamental part of their treatment plan. Veterinary and prescription diets are scientifically formulated with precise nutrient ratios, controlled mineral levels, and highly digestible ingredients to manage chronic illnesses, support organ function, and improve overall quality of life. At Petstock, we range trusted, clinically proven therapeutic brands—including Hill’s Prescription Diet and Royal Canin Veterinary Health Nutrition—to ensure your dog or cat gets the exact care recommended by your veterinarian.

Specialised Formulas for Key Health Conditions

Our prescription food collection covers a wide spectrum of health requirements, making it easy to find the exact formula prescribed for your pet:

• Weight & Mobility Support: Synergistic diets designed to burn fat, preserve lean muscle, and reduce joint inflammation—helping overweight pets shed kilos while easing stiffness and joint discomfort.

• Diabetic & Blood Sugar Management: High-protein, high-fibre, and low-glycaemic formulas formulated to prevent blood sugar spikes and regulate glucose levels for pets with diabetes.

• Gastrointestinal & Digestive Health: Highly digestible diets enriched with prebiotic fibres, electrolytes, and low fat levels to soothe acute gastroenteritis, irritable bowel, and sensitive stomach flare-ups.

• Urinary Tract Care: Dissolving and preventive formulas with strictly controlled mineral levels (magnesium, phosphorus, and calcium) to dissolve struvite stones and reduce the risk of calcium oxalate crystals.

• Dental & Oral Care: Specially structured kibble designs that provide a mechanical brushing action to reduce plaque, tartar build-up, and bad breath as your pet chews.

• Kidney & Renal Health: Low-phosphorus and restricted high-quality protein recipes designed to reduce the workload on failing kidneys and slow the progression of Chronic Kidney Disease (CKD).

• Skin & Food Sensitivities: Hypoallergenic and hydrolysed protein diets that bypass common allergens to eliminate food-related skin irritation, hot spots, and digestive distress.

• Calming & Stress Support: Therapeutic diets fortified with natural soothing ingredients (like L-tryptophan and milk protein hydrolysate) to help manage stress-induced health conditions such as feline lower urinary tract disease (FLUTD) or anxiety.

Frequently Asked Questions About Prescription & Vet Diets

Do I need a veterinarian’s recommendation to purchase prescription pet food?
Yes. Prescription and veterinary diets address specific medical conditions and contain precise nutrient levels that differ from standard retail pet food. Feeding a therapeutic diet without professional guidance could mask underlying symptoms or supply incorrect mineral balances. Always consult your veterinarian before starting or changing a therapeutic diet. If you need expert advice or an updated recommendation, our PETstock Vets are here to help—visit our Vet Services page to learn more or book an appointment.

Can I mix prescription dry kibble with prescription wet canned food?
In most cases, yes! Mixing wet and dry versions within the same therapeutic range (for example, Hill's c/d dry with Hill's c/d wet stew) is a great way to boost hydration, increase palatability, and add variety to your pet's bowl. Always verify with your vet or check product guidelines to ensure the formulas are complementary.

How long will my pet need to stay on a prescription diet?
This depends on the health condition being treated. Some diets—such as acute digestive recovery formulas—are fed short-term until symptoms resolve. Others, such as renal, urinary, diabetic, or allergy diets, are intended for lifelong feeding to maintain stability and prevent relapse. Your veterinarian will advise you during routine check-ups.

How do I transition my pet to a new prescription food?
Pets with health issues are often sensitive to sudden dietary shifts. Transition your pet gradually over a 7-day period by mixing increasing amounts of the new prescription food with decreasing amounts of their current diet until they are eating 100% of the new formula.
