Hill's Science Plan Mature Adult 7+ Medium review

38.2/100Average
DryAdultSenior

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
  1. 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.

What's in it
  • MaizeLess often behind food reactions than wheat.
  • Wheat
  • Chicken and turkey meal12% poultry, 7% chickenDried before inclusion, so it gives more protein than the figure suggests.
  • Animal fatThe main energy source. No animal named.
  • DigestSprayed on for palatability; source not given.
  • Vegetable oil, flaxseedFlaxseed for plant omega 3.
  • Dried beet pulp, mineralsA fermentable fibre most guts get on with.
  • Oat bran, fructo-oligosaccharides (ActivBiome+)0.6%
  • Pork cartilage, crustacean shell hydrolysateChondroitin and glucosamine sources, no dose printed.

Zinc at 134 mg and iron at 76.4 mg per kilo lead a dosed trace-mineral panel with selenium.

Crude fibre is low at 1.9%, little help to a dog that needs bulk to stay regular.
