Iams Advanced Nutrition Adult Small & Medium Breed: Lamb review

62.1/100Good
DryAdult

The Iams house recipe with more meat put at the front of it, and both bags sit in our Good band. What sets the pair apart is a declared moisture figure, so nothing in the dry-matter maths is assumed. Estimated carbohydrate stays a little below the usual dry food load.

Our view

Likely to suit

  • Small and medium adults that get on with chicken and turkey, the two animals doing nearly all the work
  • Owners who want moisture declared on the label
  • A gut that appreciates a prebiotic: fructooligosaccharides and dried beet pulp on both lists
  • Fussier small dogs, with chicken gravy in the recipe to keep the kibble tempting

Worth watching

  • Pork fat in both, and fish oil in the chicken bag
  • Lamb at 4% sits well behind the poultry, so the lamb bag will not sidestep a poultry sensitivity

The score, in context
  1. Fresh Chicken 62.3
  2. Lamb 62.1

All two Good. Typical dry food: Good.

A cereal-led back half and plain mineral forms keep the pair in the middle of the shelf, while the dried meat share is the biggest in this part of the Iams line.

Lamb is 4%, so this bag is poultry-based and will not suit a dog avoiding chicken or turkey.

The fish-free choice of the two.

Both bags open on dried chicken and turkey, 27% on the chicken and 29% on the lamb, with barley and maize carrying the starch and no maize flour in either. Pork fat, dried beet pulp at 2.5%, chicken gravy, linseed and fructooligosaccharides at 0.2% are common to both. Moisture is declared at 9%, so the dry-matter figures rest on the label. The chicken bag adds fresh chicken and fish oil; the lamb bag swaps them for lamb at 4%.
