Sneyd's Wonderdog Wonderdog Adult Grain Free Salmon & Trout review

69.5/100Good
DryAdult

Half this kibble is fish, and every animal in it is named: salmon and trout, nothing with legs or wings. Sweet potato at 24% and peas at 9% stand in for cereal. The small print does honest work, with both prebiotics dosed.

Where to buy: coming soon

Our view

Likely to suit

  • Dogs kept off land meats; salmon and trout are the only animals named
  • A household that has left cereal behind, sweet potato, potato and peas doing the binding
  • Digestion that needs a hand. FOS and MOS are printed at 96mg/kg and 24mg/kg
  • Owners who read the small print, as almost every working entry has a percentage

Worth watching

  • Fresh fish is most of the headline weight and largely water, so the dried salmon at 12% counts for more than it looks
  • No calcium figure, the number a growing large-breed puppy needs most

The score, in context
  1. Wonderdog Adult Grain Free Salmon & Trout 69.5

All one Good. Typical dry food: Good.

Half the recipe in named fish carries it near the top of its band; the carbohydrate and the undosed mineral panel hold it there.
