Hill's Pet Food NZ — Science Diet & Prescription Diet
Hill's has been at the forefront of evidence-based pet nutrition for over 80 years. Founded by veterinarian Mark Morris Sr. in the 1940s, Hill's pioneered the concept of using food as medicine for pets — a philosophy that underpins both of their main ranges today. PetSupply stocks the complete Hill's range for dogs and cats in New Zealand, including Hill's Science Diet everyday nutrition and Hill's Prescription Diet therapeutic veterinary food.

Science Diet is Hill's everyday nutrition range — formulated for healthy pets with no medical conditions. It covers every life stage and size, with specific formulas for puppies, kittens, adults, seniors, indoor cats, large breed dogs, small breed dogs, and pets needing weight management. No prescription is needed and it's available directly through PetSupply.

Frequently Asked Questions
What is the difference between Hill's Science Diet and Hill's Prescription Diet?
Science Diet is everyday nutrition for healthy pets — no prescription needed, suitable for any dog or cat at any life stage. Prescription Diet is a therapeutic range for pets with specific diagnosed medical conditions, formulated to support clinical management of those conditions. Prescription Diet products require a valid vet prescription and should only be used under veterinary supervision.
Do I need a prescription to buy Hill's food in NZ?
It depends on the range. Hill's Science Diet does not require a prescription — you can order it directly through PetSupply. Hill's Prescription Diet requires a valid vet prescription for every product in the range. If you're unsure which range your vet has recommended, check the product name — Prescription Diet products all carry a letter code (k/d, c/d, i/d, etc.).
Is Hill's a good pet food brand?
Yes — Hill's is one of the most rigorously researched pet food brands in the world and is consistently recommended by NZ vets. Their formulations are based on feeding trials and decades of veterinary science, not marketing trends. Both the Science Diet everyday range and the Prescription Diet therapeutic range have strong clinical evidence behind them.
