Iams: the closer look
The range
Ten dry products, all under the Advanced Nutrition name. The adult small and medium and adult large breed ranges hold two recipes each. Puppy foods come in small, medium and large, and senior foods in both size groups. A light in fat adult recipe and a sensitive digestion food round out the list.
Ingredients
Chicken leads on seven products and turkey on three. Linseed is the common label extra. Glucosamine goes on the two senior recipes for joint support, and salmon oil on the sensitive digestion food.
Nutrition
Protein as fed runs 20.0 to 28.0% with fat of 10.0 to 17.0% and energy of 344 to 392 kcal per 100g. Protein and processing reads Good on nine products. Nutritional balance is the softer read, Average on six recipes and Poor on one.
Strengths
- Outstanding transparency on nine products
- Covers both breed size and life stage
- Joint support on the senior recipes
Limitations
- All dry: no wet, no raw
- Nutritional balance reads Average on six
- Chicken and turkey are the only proteins
Where it is less of a fit
- If wet or raw food is what your dog needs, check the formats here, as all ten products are dry
- If you want nutritional balance to read higher, check that pillar, which is Average or below on seven products
- If a wider protein choice matters, check the ingredient lists: chicken leads on seven products and turkey on three
