Dr John Flake review

42.8/100Average
DryAdultSenior

A cereal-led complete food with a list short enough to read at a glance. Wheat and maize lead and poultry meal follows, and our Average band reflects how much of the bowl the grain takes. For a settled dog that has always eaten cereal kibble, it is easy, familiar feeding.

Our view

Likely to suit

  • Adult and senior dogs that have eaten wheat and maize for years without trouble
  • A label you can take in quickly, with no botanical tail
  • One bag for toy breeds and giants alike
  • Steadier dogs well off the working circuit. Fat is declared at 7.0%

Worth watching

  • Wheat first on the list. With a known wheat intolerance, a grain-free recipe suits better
  • Poultry meal names chicken for only 11% of the food, too loose for a strict elimination diet

The score, in context
  1. Dr John Flake 42.8

All one Average. Typical dry food: Good.

The gap to the typical adult kibble is built into the recipe, and a healthy adult can do perfectly well on it.

What's in it
  • WheatWhere most of the energy comes from. If a dog has itched or had a rumbling gut before, test wheat first.
  • Maize
  • Poultry meal11% chickenConcentrated before mixing, so it carries real protein. Poultry covers any domestic bird; only the chicken share is pinned down.
  • Chicken fat, chicken gravyBoth named to an animal, there as much for taste as nutrition.
  • Minerals
  • LinseedPlant omega 3 and some fibre.
  • Yeast, yucca extractThe yucca is there to cut stool odour.
