Our view

Likely to suit

  • Older small and medium dogs who like fish, the only animal protein here
  • A meatier bowl for a senior
  • Stiffening joints, with glucosamine declared at 0.045%
  • A temperamental digestion: two named prebiotics and beet pulp at 3%
  • Grain-free households. Sweet potato replaces cereal entirely

Worth watching

  • Pork fat under the fish, so a strict fish-only elimination trial is not covered
  • Fish meal with no species named
  • Chondroitin sulphate at only 0.0045%. Treat the glucosamine as the working half of the pair

The score, in context
  1. Eukanuba Grain Free Senior Small/Medium Breed Rich in Ocean Fish 45.8

All one Average. Typical dry food: Good.

A sizeable plant base and an unnamed fish hold it a step below the typical, and for a small or medium senior on fish it is a stronger bowl than that suggests.

What's in it

  • Dried sweet potatoes20%Heads the plant base; no cereal.

Named ingredients

Fish meal (31%), dried sweet potatoes (20%), whole peas, dried potatoes, pork fat, sunflower oil, fish gravy, dried beet pulp (3%), minerals (including sodium hexametaphosphate 0.39%), fructooligosaccharides (0.29%, a natural prebiotic), mannanoligosaccharides (0.15%, a natural prebiotic), glucosamine (from animal tissues) (0.045%), chondroitin sulphate (0.0045%).
Against the range

One grain-free, fish-led senior kibble. Fish meal at 31% is the largest entry and goes in already dried, so most of that share survives into the kibble. Sweet potato, peas and potato make the plant base with no cereal. The joint, gut and dental extras are all printed with doses, though the fish is never pinned to a species.
