Dr John Grain Free review

65/100Good
DryPuppyAdult

A grain-free kibble that opens on poultry meal declaring 33% chicken, with sweet and white potato in place of cereal. Green-lipped mussel extract sits in the tail for the joints. It lands in our Good band, level with the typical adult dry food, and the label covers puppies too.

Our view

Likely to suit

  • Homes where grain is out
  • Older or stiffening dogs, with green-lipped mussel extract on the list
  • A puppy and an adult sharing one bag
  • Owners who want the meat share spelled out, 33% chicken inside the meal

Worth watching

  • Green-lipped mussel is shellfish, so not for a dog kept off marine sources
  • No calcium declared, the number a large breed puppy needs most

The score, in context
  1. Dr John Grain Free 65.0

All one Good. Typical dry food: Good.

Built on construction more than flourish: a third chicken meal and starch kept in proportion.

What's in it
  • Poultry meal33% chickenDried and concentrated, so this third is dense protein, not water.
  • Sweet potato15%Beta carotene and a slower-release starch.
  • White potato11%The plainer binder. Neither potato carries gluten.
  • Chicken fat, chicken gravy
  • Vegetables6% peasFibre and a little plant protein; the rest of the line is unnamed.
  • Beet pulp, alfalfa1.5% beet pulpA moderate fermentable fibre, and plant minerals.
  • Potato proteinLifts the protein figure, so not every point of the 25.0% is chicken.
  • Minerals, linseedLinseed for plant omega 3.
  • Sage, oregano, mint, rosemary, turmeric, gingerSeasoning more than substance.
  • Green-lipped mussel extract, yucca extractMussel for its omega 3 profile and the joints; yucca for a less pungent garden.

Calcium is not declared. For large breed puppy growth, ask the maker.

The label's medium dog band asks 200 to 360 grams for a 10kg to 20kg dog, so let condition be the guide.

Budget end of the market for a dry food, fairly priced for what the analysis shows.
