Hill's Science Plan Mature Adult 7+ Medium review
The straight-down-the-middle member of Hill's mature line, in our Average band: no calorie control, no small kibble, an everyday bowl for a medium dog in its later years. Maize and wheat come first. The band reflects that cereal share more than the care taken over the recipe.

Our view
Likely to suit
- Medium dogs of seven and over with nothing in particular to fix
- Trying a bag before committing, with 2.5kg up to 18kg on offer
- Joints starting to tell, from the pork cartilage and shell hydrolysate
- An unenthusiastic appetite. Digest is sprayed on to make kibble worth eating
- Trace minerals given as doses, zinc at 134 mg per kilo
Worth watching
- Carbohydrate at 59.3% of dry matter against 46.2% typical
- A modest meat share, poultry at 12%
- Animal fat and digest name no animal, so one protein cannot be pinned down

The score, in context
- Hill's Science Plan Mature Adult 7+ Medium 38.2
All one Average. Typical dry food: Good.
The cereal share sets the band; what a score cannot capture is consistency, the same kibble and analysis bag after bag.
