Iams Advanced Nutrition Adult Large Breed: With Fresh Chicken review

57.4/100Good
DryAdult

A widely stocked everyday kibble for big adult dogs, with both recipes in our Good band and next to nothing between them. Dried chicken and turkey lead each bag. The difference is only the finish: fresh chicken in one, a little lamb in the other.

Our view

Likely to suit

  • Large breed adults that get on with poultry
  • Owners who want portions spelled out, from 25kg dogs to 90kg dogs
  • Dogs that digest cereal happily
  • Homes keeping an eye on tartar

Worth watching

  • Only 4% lamb in the lamb bag, with chicken and turkey still leading
  • Pork fat in both recipes

The score, in context
  1. With Fresh Chicken 57.4
  2. With Lamb 57.0

All two Good. Typical dry food: Good.

Nothing alarming holds either back; barley and maize push the carbohydrate past the dry-food norm.

What's in it
  • Dried chicken and turkey22% (chicken 13%)The workhorse: its water is gone, so it arrives close to as written.
  • Barley, maize, maize flourCarry the starch. Barley is a gluten grain.
  • Fresh chicken10%Reads generously but cooks down to a fraction of that.
  • Pork fatA named animal fat, and pork is a meat many dogs have barely met.
  • Dried beet pulp2.5%Firm stools.
  • Chicken gravy

The simpler starting point of the two, with poultry and the pork fat as its only animals.

Two large-breed kibbles built the same way: dried chicken and turkey at the front, barley and maize carrying the starch, then pork fat, beet pulp and a mineral mix with a tartar softener. One finishes with 10% fresh chicken, the other with 4% lamb.

Protein converts to 25.0% of dry matter in both and energy is 372 kcal per 100 grams, so swapping needs no change to the scoop. Moisture is not declared.
