Hill’s Science Diet Adult Lamb Meal & Brown Rice is the kibble we recommend when an owner has identified a clear reaction to chicken-based food but does not need a prescription hydrolyzed protein diet. We tested it for 6 months on a 24 kg boxer mix who had been losing weight on a previous chicken kibble after a flank dermatitis flare. By month two on this lamb formula the dog had no new skin events, by month four she had regained 1.4 kg of lean weight, and her daily Purina stool score sat at an average of 3.5.
Why you should trust this review
We bought the bag at retail from a Petco store with no manufacturer involvement. The reviewer is the dog’s regular owner and has logged her food, weight, and skin events for our coverage of pet nutrition since 2024. The dog’s vet had confirmed a chicken protein reaction six months prior to the test, so this was a real-world chicken-free trial rather than a curiosity test.
How we tested Hill’s Lamb Meal & Brown Rice
- 6 month feeding window, November 2025 through April 2026
- One 24 kg boxer mix with documented chicken reactivity
- Daily stool log on the Purina fecal scoring chart
- Weekly weight check on a vet office floor scale
- Monthly photo of the original flank dermatitis area
- Transition followed Hill’s recommended 7 day step-up
Our full pet food methodology is documented at /methodology.
Who should buy Hill’s Lamb Meal & Brown Rice?
Buy if your adult dog reacts to chicken-based kibble, you want a vet-stocked formula without paying for prescription, and you prefer a recipe that excludes corn and wheat.
Skip if your dog tolerates chicken kibble already, if you need a true grain-free diet, or if you only have access to giant 50 lb bags because the largest size here is 33 lb.
Stool quality: steady and predictable
Daily stool scores moved from a 5.0 average on the previous chicken formula to a 3.5 average by week 6 on this lamb recipe and held there. The 3 percent maximum crude fiber and the brown rice plus barley combination produced firm but not dry results. We saw no episodes of vomiting tied to mealtime.
Skin and coat: no new flares, original patch healed
The flank dermatitis area photographed clean by month three, and no new patches appeared during the 6 month window. We are not crediting the food alone; the previous chicken protein reaction had been the likely driver, and removing chicken was the variable.
Palatability: accepted without coaxing
The dog ate the lamb formula without hesitation from day one of the transition mix. The kibble piece is roughly 9 to 10 mm, similar to the regular Hill’s adult chicken recipe.
Value and packaging
At $79.99 for a 33 lb bag, the cost works out to $2.42 per pound. That is a slight premium over Pro Plan Lamb & Rice but the recipe excludes corn and wheat, which Pro Plan does not.

Is Hill's Lamb Meal & Brown Rice worth $80 in 2026?+
If your dog reacts to chicken-based kibble, yes. The first ingredient is concentrated lamb meal, the recipe excludes corn and wheat, and the AAFCO label covers adult maintenance.
Hill's Lamb Meal vs Pro Plan Lamb & Rice: which is better?+
Pro Plan uses fresh lamb as the first ingredient, which sounds nicer but contains more water. Hill's uses lamb meal which is denser protein per kilogram. Both are AAFCO complete; Hill's is easier to find at vet offices.
How accurate is the calorie label?+

Can I feed this to a dog with grain sensitivities?+
It contains brown rice and barley. If your vet has confirmed a true grain hypersensitivity, choose a grain-free lamb formula instead. If the issue is corn or wheat, this recipe excludes both.
Does it stain a light-colored carpet if my dog vomits?+
The kibble has visible brown tones. Owner reviews mention staining when undigested kibble is left to sit. Clean promptly.
