Hill's Science Plan Large Breed Adult Dog Food with Lamb and Rice review
A cereal-based kibble built around a big dog's frame, sitting in our Average band because grain and plant protein do so much of the carrying. Its large-breed thinking arrives late on the list: pork cartilage and crustacean shell bring chondroitin and glucosamine into the recipe. As a steady daily food for a big adult with stiffening joints, it has a clear purpose.
Our view
Likely to suit
- Large adults with the first signs of joint wear
- Owners after a red meat over yet another chicken recipe, with lamb meal the named animal
- A big dog on a rice-based food
- Dogs that have always done well on a familiar cereal kibble
Worth watching
- Wheat and soybean meal high on the list, wheat being the grain a sensitive dog most often reacts to
- Pig and shellfish sit alongside the lamb, through the joint sources
- Carbohydrate at an estimated 54.2% of dry matter against a typical 46.2%

All one Average. Typical dry food: Good.
How the recipe is stacked puts the distance in: grain and plant protein ahead of the lamb pull protein and processing down, while naming the lamb, rice and joint sources holds transparency up.
