Hill's Science Plan Medium Mature Adult Dog Food with Lamb and Rice review

36.1/100Average
DryAdultSenior

The mature medium formula with a red meat in place of the bird, which makes it the obvious pick in the range for a dog that has gone off poultry. It sits in our Average band, shaped by how much cereal and plant protein the recipe uses. Lamb meal is declared at 8%, behind maize, wheat and broken rice.

Our view

Likely to suit

  • Medium breed dogs in their mature years that have lost interest in chicken and turkey
  • Lamb as the named meat, declared at 8% in its dried meal form
  • Older joints: pork cartilage supplies chondroitin and a crustacean shell hydrolysate supplies glucosamine
  • Trace minerals as printed doses, zinc at 158 mg and iron at 90.3 mg per kilo
  • Dogs that eat better when the kibble tastes of something, with digest sprayed on for exactly that

Worth watching

  • Lamb led, not lamb only: animal fat, digest and pork cartilage are animal ingredients too
  • Soybean meal and maize protein meal lifting the protein figure without adding meat
  • Carbohydrate at an estimated 59.0% of dry matter against 46.2% typical, better for a steady dog than a hard working one

The score, in context
  1. Hill's Science Plan Medium Mature Adult Dog Food with Lamb and Rice 36.1

All one Average. Typical dry food: Good.

Limited named meat, two plant protein contributors and a heavy cereal share account for the score; nothing is wrong with the lamb.

What's in it
  • Maize, wheatCereal is the base of this bowl.
  • Broken rice12%The fragments milling leaves behind; it behaves exactly as whole rice does.
  • Lamb meal8%Rendered and dried, so more protein per gram than fresh lamb at the same percentage.
  • Soybean mealConcentrated plant protein, and one of the more common triggers in dogs that react to food.
  • Animal fat, digestNo species attached to either.
  • Flaxseed, vegetable oilPlant omega 3 from the flax.
  • Maize protein mealPlant protein again.
  • Dried beet pulp, minerals, oat bran, fructo-oligosaccharides0.6% (ActivBiome+ blend)
  • Pork cartilage, crustacean shell hydrolysateChondroitin and glucosamine. The cartilage brings pork into the bowl.

Iron, iodine, copper, manganese, zinc and selenium dosed per kilo, zinc the largest at 158 mg.

Middle of the market for a dry food, and a little more than the analysis on its own would justify.
