Iams Advanced Nutrition Puppy Large Breed review

63.9/100Good
DryPuppy

A poultry-led growth kibble in our Good band, and the reason to buy it is the calcium line. It converts to 1.2% of dry matter, inside the range a big pup's skeleton wants while bone is laid down. Fat is moderate at 15.2% of dry matter, so the pace stays steady.

Our view

Likely to suit

  • Large-breed puppies, exactly who the bag is labelled for
  • Owners who want the calcium figure printed, not guessed at
  • Big pups being brought on at a measured pace
  • Anyone who likes every fat identified: sunflower oil, pork fat and fish oil

Worth watching

  • Chicken, turkey, pork and fish all on one label, so it will not suit a single-protein plan
  • Carbohydrate at 47.2% of dry matter, well above the 39.0% typical of a puppy kibble

The score, in context

All one Good. Typical dry food: Good.

An Outstanding label holds it up, and a cereal-heavy analysis pulls nutritional balance down to Average.
