Iams Advanced Nutrition Senior Large Breed review

58.6/100Good
DryAdultSenior

The house recipe adjusted for age: fat down to 10%, protein held at 25%, and glucosamine printed for joints that have carried a heavy frame for years. Dried chicken and turkey lead, barley and maize do the carrying. It finishes in our Good band, level with the typical adult dry food.

Our view

Likely to suit

  • The big dog getting on in years, the very dog on the front of the bag
  • Older dogs softening round the middle; fat is held to 10% at 358 kcal per 100 grams
  • Joint support built into the food, with glucosamine declared at 0.045%
  • An older dog's teeth. Sodium hexametaphosphate at 0.35% softens tartar

Worth watching

  • Carbohydrate at 52.4% of dry matter against 46.2% typical for adult dry food
  • Pork fat as the added fat, for a dog with a pork sensitivity

The score, in context
  1. Iams Advanced Nutrition Senior Large Breed 58.6

All one Good. Typical dry food: Good.

An older big dog moving onto it is not settling for less than the market average; cereal-heavy construction holds it there, the trimmed fat and printed glucosamine aim it squarely at its dog.

Against the range

Dried chicken and turkey at 25% lead, with fresh chicken at 10% behind barley and maize. Pork fat holds fat to 10%, and glucosamine from animal tissues is declared at 0.045%. Moisture is not declared, so the dry matter figures assume 8%.

Budget end of the market for a dry food, and a touch dear for what the analysis shows.
