Hill's Science Plan Mature Adult 7+ Light Medium review
A light senior kibble for medium dogs that holds calories down without leaving the bowl bare. Energy runs at 313 kcal per 100g against the 357 typical of adult dry food, and cellulose is how it gets there. It lands in our Average band, a reading driven by the cereal base.

Our view
Likely to suit
- Medium dogs of seven and up who need the calories reined in
- An older dog quietly getting rounder on the same portion
- Dogs that beg between meals: fibre at 12.1% makes a portion sit heavier for longer
- Joint ingredients as standard, pork cartilage and crustacean shell hydrolysate both listed
- Trace minerals printed as doses, zinc at 133 mg per kilo
Worth watching
- Chicken is only 9%, inside 15% poultry meal, so meat is not the bulk of the recipe
- Maize and wheat lead, which matters for a dog that has reacted to either
- Animal fat and digest name no animal, a gap for a strict elimination plan

What's in it
- Maize, wheatCereal carries the structure.
- Chicken and turkey mealchicken 9%, total poultry 15%Already dry, so it carries more protein than the same share of fresh meat.

- Pea bran meal
- Digest, animal fatNo species named, the weakest point on the label.
- Dried beet pulpA fermentable fibre most guts get on with.
- Flaxseed, vegetable oilFlaxseed is the plant omega source.
- Minerals
- Oat bran, fructo-oligosaccharides (ActivBiome+)0.6%Feeds the bacteria a dog already has.
- Pork cartilage, crustacean shell hydrolysateChondroitin and glucosamine sources, not dosed in print.
