Iams Advanced Nutrition Light in Fat Adult All Breed review

48.8/100Average
DryAdultSenior

The calorie-controlled bag in the Iams range, and honest about how it gets there. Fat is held to 10%, and barley and maize fill the space the fat leaves. Cereal leads by design, so it lands in our Average band, doing exactly the job a dog with a little to lose needs.

Our view

Likely to suit

  • Dogs carrying more than their frame wants, at 344 kcal per 100 grams
  • Feeding a grown dog and an ageing one from the same bag
  • Homes with dogs of different sizes; the feeding table runs from 2kg to 80kg
  • Omega 3 on a lighter diet, from fish oil and linseed

Worth watching

  • Carbohydrate at 58.6% of dry matter, against 46.2% typical
  • Fish oil on the list, for a fish-free household
  • No moisture declared, so the dry-matter figures start from an assumed 8%

The score, in context
  1. Iams Advanced Nutrition Light in Fat Adult All Breed 48.8

All one Average. Typical dry food: Good.

The distance from the middle of the shelf comes from the calorie work the recipe is built to do, and that work is the whole attraction for the dog it is meant for.
