Hill's Pet Nutrition is one of the most trusted and vet-recommended pet food brands in the world, with over 75 years of nutrition research behind its recipes. Founded by veterinary surgeon Mark Morris Sr., who originally developed a specialised kidney diet for a guide dog, the brand has been built on science-led nutrition ever since. Hill's produces two core ranges — Hill's Science Plan, designed for healthy pets at every life stage, and Hill's Prescription Diet, formulated to help manage specific medical conditions under veterinary guidance. Both ranges are available for dogs and cats, covering puppies and kittens through to seniors. Hill's Science Plan is consistently recommended by vets as a high-quality everyday food, while Hill's Prescription Diet is regarded as one of the most clinically proven therapeutic pet food ranges available. The full Hill's range is available at petshop.co.uk with next-day delivery at petshop.co.uk when you order before 7pm.

Hill's Science Plan is formulated for healthy pets at all life stages — it provides complete, balanced everyday nutrition and is available to buy without a vet's prescription. It includes targeted ranges for weight management, sensitive stomachs, and specific life stages including puppy, adult, and senior. Hill's Prescription Diet is an entirely separate range formulated to help manage specific medical conditions such as kidney disease, urinary issues, digestive disorders, obesity, diabetes, and allergies — and should only be used under the guidance of a vet. Hill's is clear that Prescription Diet products are not substitutes for Science Plan and vice versa. If your vet has recommended a Prescription Diet product, it is because your pet has a clinical need that requires targeted therapeutic nutrition. Both ranges are available at petshop.co.uk with next-day delivery at petshop.co.uk when you order before 7pm.

Hill's covers a wide spectrum of needs across its two ranges. Hill's Science Plan is best suited to owners looking for a vet-backed, science-led everyday food for a healthy dog or cat, with dedicated formulas for puppies, junior dogs, adults, seniors, and large breeds, as well as targeted options for weight management, sensitive stomach and skin, oral care, and healthy mobility. Hill's Prescription Diet is best suited to pets with a diagnosed health condition, with specialist formulas covering kidney support, urinary health, gastrointestinal issues, liver care, joint support, and allergy management among others. Both ranges cover dogs and cats. The full Hill's range is available at petshop.co.uk with next-day delivery at petshop.co.uk when you order before 7pm.

Hill's Science Plan recipes are built around high-quality animal proteins — including chicken, turkey, lamb, salmon, and tuna — as the primary ingredient, alongside digestible carbohydrates such as maize, rice, and barley. Recipes include omega-3 and omega-6 fatty acids for skin and coat health, and are enriched with vitamin E and antioxidants to support immune function. Adult and senior Science Plan recipes feature ActivBiome+ Multi-Benefit — a proprietary blend of prebiotic fibres clinically shown to nourish the gut microbiome and promote overall vitality. Hill's Science Plan is complete and balanced across all recipes, formulated with input from over 200 veterinarians and nutritionists. The cat food range includes added taurine, which is essential for cats' heart function and vision. Full ingredient lists for every Hill's product are available on the individual product pages at petshop.co.uk.

Yes — Hill's Science Plan includes a dedicated Sensitive Stomach and Skin range for both dogs and cats, specifically formulated for pets prone to digestive upsets or skin reactions. This range uses highly digestible ingredients, prebiotic fibres to support gut health, and added vitamin E and omega fatty acids to support skin and coat condition. For pets with more serious diagnosed digestive conditions, Hill's Prescription Diet Gastrointestinal Biome is clinically shown to help firm loose stools within 24 hours and is available under veterinary guidance. Owners frequently report significant improvements in digestive health after switching to the Hill's Sensitive range. Hill's Science Plan Sensitive is available at petshop.co.uk with next-day delivery at petshop.co.uk when you order before 7pm.

Hill's Science Plan includes a feeding guide on every bag and pack with recommended daily amounts based on your dog's weight and life stage. As a general guide, the daily amount is split across two meals for adult dogs and three meals for puppies. Feeding amounts vary between recipes — for example, a more calorie-dense formula such as the Performance range requires smaller portions than the standard adult recipe. Hill's also provides a body condition scoring system to help owners assess whether their dog is at an ideal weight, which should be used alongside the feeding guide to adjust portions over time. If your dog is on a Hill's Prescription Diet, your vet will advise on the appropriate feeding amount for your pet's specific condition. Full feeding guides for every Hill's product are shown on the individual product pages at petshop.co.uk.

Hill's Science Plan dry dog food bags use a resealable zip-lock closure at the top of the bag. To open for the first time, pull the two sides of the zip apart firmly from the centre outward — the bag is sealed at the top so you may need to apply a little pressure to separate it the first time. Once open, fold the top of the bag down before pressing the zip closure together to reseal — this keeps the kibble fresh between feeds. Hill's recommends storing dry food in a cool, dry place and using within six weeks of opening. If you find the resealable zip difficult to open, a small pair of scissors along the pre-scored tear line just below the zip is a quick alternative. All Hill's dry food bag sizes are available at petshop.co.uk, with next-day delivery at petshop.co.uk when you order before 7pm.

Hill's Science Plan, Royal Canin, and Purina Pro Plan are the three most consistently vet-recommended science-led pet food brands in the UK, and are frequently compared by owners looking for a trusted premium everyday food. All three are formulated by teams of veterinary nutritionists, meet WSAVA nutritional guidelines, and offer both everyday and therapeutic diet ranges. Royal Canin is unmatched for breed-specific formulas — with over 50 dedicated breed recipes — making it the strongest choice when a formula exists for your specific dog or cat. Purina Pro Plan is often considered the most affordable of the three at a similar quality level, and is particularly strong on sport and performance formulas. Hill's Science Plan stands out for its depth of clinical research, its ActivBiome+ gut health technology in adult and senior recipes, and its Prescription Diet range — widely regarded as one of the most comprehensive therapeutic pet food ranges available. All three brands are stocked at petshop.co.uk with free delivery at petshop.co.uk on orders over £59.99 and next-day delivery at petshop.co.uk when you order before 7pm.
