Hill's Science Diet - Large Breed Lamb Meal & Brown Rice Dry Dog Food

TL;DR: Hill's Science Diet Large Breed Lamb Meal & Brown Rice is a 33 lb dry dog food for adult large-breed dogs, built around lamb protein and brown rice. It includes glucosamine and chondroitin to support joint health — a practical pick for owners who want a lamb-and-rice recipe sized for bigger dogs.

Large-breed adult dogs have different needs than smaller dogs: steadier energy, lean muscle support, and extra attention to joints. This formula is tailored to those needs with a lamb-forward recipe and balanced calories suited to larger frames.

While often searched for as "Hill's Science Diet lamb and rice puppy," this specific bag is formulated for adult large-breed dogs, not puppies — worth confirming before you buy.

Feeding & use

Follow the feeding guide printed on the bag, using your dog's adult weight and activity level as the starting point. Transition gradually over 7 days by mixing increasing amounts of the new food with your dog's current food, and keep fresh water available at all times.

Store the kibble in a cool, dry place with the bag sealed to maintain freshness. If your dog has a diagnosed health condition, check with your veterinarian before changing diets.
