Overview
Large-breed puppies grow fast, and too much calcium or energy during that growth can work against healthy bones and joints. Hill’s Science Diet Large Breed Puppy is designed for puppies expected to weigh more than 55 lb as adults, with what Hill’s describes as an optimal level of calcium for controlled bone growth, plus DHA from fish oil for brain and eye development.
Chicken is the first ingredient, followed by brown rice, whole grain oats, chicken meal, cracked pearled barley and chicken fat. Hill’s has renamed this recipe over time, so you may see it as Chicken Meal & Oats on older bags or listings and Chicken & Brown Rice on newer ones.

Who it suits (and who should skip it)
It suits owners of Labrador, Golden Retriever, German Shepherd and other big-breed puppies who want a widely available, well-known growth formula. The recipe uses familiar grains rather than being grain-free, which many vets are comfortable with. Big puppies also shed and chew; our guide to getting dog smell out of a couch may come in handy.
Skip it for small and medium puppies, which need a standard puppy formula, and for adult dogs. Retailers list different upper ages, from up to one year to up to 18 months, so ask your vet when to move your dog to adult food. We could not confirm the exact AAFCO statement wording for this bag from a source we read; check that the bag’s statement covers growth, including large-size dogs.
A common mistake with big puppies is adding extra calcium, adult food or supplements on top of a puppy formula. A complete large-breed puppy food is balanced on its own, and adding more calcium works against the controlled level it was designed around. Ask your vet before adding anything, and weigh your puppy regularly so feeding amounts can be adjusted as growth slows.
How it compares
Once your dog is grown, Purina Pro Plan Sensitive Skin & Stomach and Royal Canin Medium Adult are our adult picks, the first for touchy digestion and the second for medium-size dogs. For a growing large breed, Hill’s puppy formula is the one on this page to choose. Move between foods gradually, following the transition guidance on the bag and your vet’s advice.
On the Canadian side, the 15.5 lb bag appears as 7.03 kg and shares one ASIN with Amazon.com. Canadian retailers also stock a larger 27.5 lb bag.

Frequently asked questions
When should I switch from Hill's Large Breed Puppy to adult food?
Retailers list different upper ages, from up to one year to up to 18 months, and large breeds often keep growing past their first birthday. Your vet is the best person to judge when growth has slowed enough to move to an adult formula. When you switch, do it gradually and follow the transition guidance on the bag.
Is Chicken Meal & Oats the same as Chicken & Brown Rice?
Hill's has renamed its Large Breed Puppy recipe over time, and both names appear on listings and bags. Current retailer pages list chicken, brown rice, whole grain oats, chicken meal, barley and chicken fat as the first ingredients. Check the ingredient list and guaranteed analysis on the bag you receive.
Why do large-breed puppies need special food?
Large breeds grow quickly, and too much calcium or energy during that growth can affect bones and joints. Large-breed puppy formulas control calcium and calories to support steady growth. Hill's says this recipe has an optimal calcium level for controlled bone growth. Ask your vet whether your puppy's expected adult size calls for one.
How many calories are in Hill's Large Breed Puppy?
Retailers list 3,628 kcal per kilogram, or 391 kcal per cup. Feeding amounts depend on your puppy's age, weight and expected adult size, so use the chart on the bag as a starting point and adjust with your vet at regular weigh-ins.
