Hill's Science Plan Adult 1+ Healthy Mobility Large review

39/100Average
DryAdultSenior

A food for big dogs whose joints have started to matter, built on omega 3 instead of a supplement blend. It sits in our Average band. Fish oil is declared at 1.8% with flaxseed just ahead of it, while the meat share is modest at 7% chicken and 11% total poultry.

Our view

Likely to suit

  • Large adults and older dogs, with joint-minded feeding built into the everyday meal
  • Owners who want the omega source named and given a figure
  • Big dogs carrying a shade more than their frame wants. Fat is declared at 12.9%
  • One bag for a mature adult and a senior
  • Trace minerals each printed with a figure

Worth watching

  • No glucosamine or chondroitin dose printed; the joint help is the fish oil and flaxseed
  • Fish oil on the list, so not for a dog kept away from fish
  • Wheat and maize open the list, with carbohydrate at an estimated 57.2% of dry matter
  • Protein at 19.7%, gentle for a large dog in hard work

The score, in context
  1. Hill's Science Plan Adult 1+ Healthy Mobility Large 39.0

All one Average. Typical dry food: Good.

The distance from the middle of the dry shelf comes from how little of the bowl is animal, not from anything a large dog would object to.

What's in it
  • WheatFirst, which sets the shape of the kibble.
  • Maize
  • Chicken and turkey meal11%Chicken 7% within it. Already dried, so little is lost in cooking.
  • DigestThe palatant that makes a lean kibble worth eating. Unusually high, and no animal named.
  • Animal fatNo species, so the label cannot be read as poultry only.
  • Maize protein meal
  • Flaxseed, fish oil1.8% for the fish oilThe mobility case: marine omega 3 in a daily helping.
  • Vegetable oil, minerals
  • Pea bran mealSupplies the fibre.

Each trace mineral carries a figure, zinc at 136 mg and iron at 77.8 mg per kilo among them, with a natural antioxidant as the preservative.

A large dog scales up well beyond the 15kg daily figure.

Middle of the market for a dry food, and you pay a little more than the analysis alone would justify.
