Chicken Meal

This recipe has been specially tailored for large breed puppies, providing sufficient calcium levels for proper bone development and protein sources from savory chicken meal and oats, fish oil, flaxseed as well as the antioxidant vitamins C & E which may help prevent disease.

Chicken Fat

Chicken fat is a highly digestible animal-based source of energy and offers essential linoleic acid (omega-6) and omega-3 fatty acids to support puppy development.

Puppies require high-energy foods for proper development, yet must adhere to caloric intake limits in order to prevent skeletal abnormalities. Large breeds often expend more calories than most other dogs and require a diet tailored specifically for them in order to prevent orthopedic issues such as hip dysplasia.

Giant breed pups require food with the appropriate calcium content and calcium:phosphorus ratio to help manage bone development, and Hill’s science diet large breed puppy formula has been designed specifically for these pups.

Brewer’s Rice

This recipe is tailored for large breed dogs up to 100 lb and features lamb as an excellent source of protein and animal fat, along with chicken by-product meal as a source of chondroitin sulfate sourced from non-prime cuts of slaughtered chicken, such as beaks, feet or undeveloped eggs.

Brewer’s rice, which is a low-grade grain byproduct, makes up much of this food’s carbohydrate content and may contribute to hormonal imbalance in certain dogs. Furthermore, it contains phytoestrogens which may contribute to hormone disruption as well as being high in sodium content.

Yellow Peas

Pea protein has recently come under scrutiny due to unwarranted criticism; however, it actually provides many unique advantages. Pea protein is high in albumin which is the most abundant circulating protein and offers anti-inflammatory benefits.

Yellow peas are an excellent grain-free source of protein and fiber, providing important vitamins and minerals. A type of legume like beans, chickpeas and lentils, they feature unique fiber with low glycemic index that may help control blood sugar levels while simultaneously offering antioxidants and phytonutrients to provide further health benefits.


Hill’s Science Diet produces nutrition for puppies of all sizes and breeds, prioritizing research into creating nutritionally balanced food over finding sources for healthy ingredients.

This recipe utilizes barley, a cereal grain known for being high in fiber and packed with essential nutrients like copper and magnesium that work together to protect against oxidative stress.
