Hill's Science Plan Perfect Weight Adult Dog Food with Chicken & Vegetables review

41.1/100Average
WetAdultSenior

A light weight-loss tray that does the calorie job properly: crude fibre lifted to 3.4% as fed and energy held to 90 kcal per 100g. It lands in our Average band because so much of it is declared by category. Chicken is named at 4%, vegetables at 7%, and no cereal appears by name.

Our view

Likely to suit

  • Adult and older dogs carrying more weight than they should
  • Dogs that beg between meals. Fibre at 3.4% as fed is high for a wet food, and fibre keeps a dog feeling fed
  • Owners counting calories, at 90 kcal per 100g against the 97 typical of adult wet food
  • Small adults and seniors, the size and life stage Hill's lists it for
  • Households that would sooner not see a named cereal in the bowl

Worth watching

  • Only chicken is named, at 4%. The rest is meat and animal derivatives, so no elimination diet can be built on it
  • Derivatives of vegetable origin can cover grain products, so this is no grain-free promise
  • Neither moisture nor ash is declared, so there is no dry matter conversion

The score, in context
  1. Hill's Science Plan Perfect Weight Adult Dog Food with Chicken & Vegetables 41.1

All one Average. Typical wet food: Excellent.

The score is held back by how much of the label is written in category terms, while the calorie work it does is sound.

What's in it
  • Meat and animal derivatives (chicken 4%)4% chickenA legal term that spans the whole quality range. Only the chicken is pinned, the rest could be any animal or cut.
  • Derivatives of vegetable originBroad enough to include grain products.
  • Vegetables7%Where a weight recipe earns its keep.
  • Vegetable protein extractsHelp lift protein to 7.4% as fed, from a plant that is not named. Worth knowing if soya or maize is on your avoid list.
  • Eggs and egg derivatives
  • Seeds
  • Oils and fatsNo source given for the fat.
  • Minerals, fruit

Iron at 12.4mg and zinc at 33.2mg per kilo, with copper, manganese and iodine each carrying a figure.

No moisture or ash on the label, so the dry matter figures here rest on an assumed moisture.

Named ingredients

Meat and animal derivatives (chicken 4%), derivatives of vegetable origin, vegetables (7%), vegetable protein extracts, eggs and egg derivatives, seeds, oils and fats, minerals, fruit.

Roughly 929 grams covers a 15kg adult at maintenance; a dog on a reducing plan eats less than that.

Middle of the market for a wet food, and a premium for what the analysis shows.
