Eukanuba Thriving Mature Medium Breed review

57.1/100Good
DryAdultSenior

A medium breed senior kibble that leads the right way, with dried chicken and turkey first at 22% and fresh chicken at 19% behind. It lands in our Good band. Protein at 26% and fat at 12% is a sensible middle setting for a dog whose pace has come off but whose appetite has not.

Our view

Likely to suit

  • Medium breed adults and seniors
  • A bag that opens with dried meat, the chicken share printed at 16%
  • Dogs stiffening after a long walk, glucosamine declared at 0.04%
  • Older dogs whose protein should stay up
  • Steady households: 3kg, 12kg and 15kg bags

Worth watching

  • Maize and wheat as the two largest plant entries
  • Poultry fat with no bird named, so duck and goose stay possible
  • Glucosamine only; no chondroitin declared on this size

The score, in context
  1. Eukanuba Thriving Mature Medium Breed 57.1

All one Good. Typical dry food: Good.

Cereals doing much of the carrying and a fat named only by family keep it to an ordinary adult reading, with the meat entries declared properly.
