Hill's Science Plan Perfect Weight Medium Adult Dog Food with Chicken review
A calorie-controlled kibble for the medium dog carrying a size more than he should, and it sits in our Good band. Cellulose lifts crude fibre to 11.9%, so a full-looking bowl brings fewer calories. Energy settles at 317 kcal per 100g, against 357 for the typical adult dry food.

Our view
Likely to suit
- Medium adults who need to slim without staring at an empty bowl
- Owners who want the portion to stay generous while the calories come down
- An older medium dog. One bag covers the adult and senior years
- Dogs that get on with poultry, the only meat family named
Worth watching
- Wheat and maize, for a dog with a history of trouble with cereals
- Bulkier, more frequent stools while a dog settles onto this much fibre
- Maize protein meal propping up the protein figure, so it reads higher than the meat alone
