Eukanuba Thriving Mature Large Breed review

59.6/100Good
DryAdultSenior

A cereal-based kibble for big dogs past their prime, in our Good band. Both joint supplements are declared on the label, the two that large breed owners usually end up buying separately. Fresh chicken at 20% leads, and Eukanuba prints the chicken share of the dried poultry at 13%.

Our view

Likely to suit

  • Big dogs in their later years, the dog this is formulated and portioned for
  • Owners already buying joint supplements: glucosamine at 0.04% and chondroitin sulphate at 0.004% are declared
  • Dogs whose exercise has eased off. Fat is kept to 10.5%
  • Tartar help in the everyday bowl, from sodium hexametaphosphate at 0.34%
  • A giant breed working through food quickly, in 12kg or 15kg bags

Worth watching

  • Wheat and maize as the two biggest plant entries; move a dog with a cereal history over carefully
  • Carbohydrate at 53.8% of dry matter against 46.2% typical
  • A small chondroitin dose, so keep a dog on the vet's own joint supplement
  • Poultry fat that names the family, not the bird

The score, in context
  1. Eukanuba Thriving Mature Large Breed 59.6

All one Good. Typical dry food: Good.

Named meats with printed shares earn it a place level with the typical adult dry food; cereals in four of the top six places keep it there.

What's in it
  • Fresh chicken20%Most of its water leaves in cooking.
  • Dried chicken and turkey18%Chicken is 13% of it. This entry carries most of the finished protein.
  • Maize, wheat, maize gritsGrits are the refined starch fraction of the maize.
  • Oats, barley, sorghumOats and barley are the more nutritious of the cereals.
  • Dried beet pulp2.1%The fibre.
  • Chicken gravy, poultry fatPoultry fat withholds its species.
  • Minerals, with sodium hexametaphosphate0.34%Makes it harder for tartar to bind.
  • Fructooligosaccharides0.25%
  • Dried whole egg, brewer's dried yeast
  • Glucosamine, chondroitin sulphate0.04%, 0.004%Helpful background, no substitute for a vet's supplement.

Vitamins A, D3 and E with beta-carotene and L-carnitine, and zinc, iron, manganese, copper and iodine as sulphates, all dosed per kilo.

Named ingredients

Fresh chicken (20%), dried chicken and turkey (18% including chicken 13%, a natural source of glucosamine, chondroitin and taurine), maize, wheat, maize grits, oats, barley, sorghum, dried beet pulp (2.1%), chicken gravy, poultry fat, minerals (including sodium hexametaphosphate 0.34%), fructooligosaccharides (0.25%, a natural prebiotic), dried whole egg, brewer's dried yeast (a natural source of B-vitamins and selenium), glucosamine (from animal tissues) (0.04%), chondroitin sulphate (0.004%).
Against the range

One cereal-based recipe for older large breeds. Fresh chicken and dried chicken and turkey lead, with the chicken share of the dried mix printed. Maize, wheat, maize grits, oats, barley and sorghum make up the plant side, and moisture is declared, so the dry-matter figures rest on the maker's own number.

Budget end of the market for a dry food, though the analysis gives back a little less than the price suggests.
