WorkingHPRs Grain Free Large Breed: Salmon with Trout, Sweet Potato & Asparagus review

65.5/100Good
DryAdult

A grain free kibble written for big dogs that keeps pace with the typical adult dry food in our Good band. Salmon and trout make up 50% of the recipe, and glucosamine, methylsulfonylmethane and chondroitin all have their doses printed. Not many large breed bags go that far.

Our view

Likely to suit

  • Large breed adults: the kibble and the feeding chart are both written for a big frame
  • Big dogs that need help at the joints, with glucosamine and methylsulfonylmethane at 170 mg/kg each and chondroitin sulphate at 125 mg/kg
  • Dogs kept off cereal. The binding is sweet potato, peas and potato
  • Fish-fed dogs, since salmon and trout supply all of the animal content
  • Changeable digestion, with FOS at 96 mg/kg and MOS at 24 mg/kg on the bag

Worth watching

  • Fish is the whole animal share, so a dog kept off it has nothing here
  • An Omega 3 Supplement with no source named, one open entry for a strict exclusion diet
  • Protein at 26.1% of dry matter, gentler than 50% fish suggests, because a third of that fish goes in fresh and loses its water

The score, in context
  1. Salmon 65.5

All one Good. Typical dry food: Good.

A label that prints its fish split and every dose earns its transparency mark; the modest protein after conversion is what holds the overall score where it is.

What's in it
  • Salmon and trout: freshly prepared salmon and trout, dried salmon, salmon stock50% (33%, 15%, 2%)The fresh share is the headline and the dried salmon does the work, having already given up its water.
  • Sweet potato24%First of the plants.
  • Peas, potato9% (peas)
  • Beet pulpThe fibre.
  • Linseed, Omega 3 SupplementPlant omega 3 from the linseed. The supplement is the one entry that keeps its source to itself.
  • Minerals, vitamins, vegetable stockVegetable stock is the other broad term on the list.
  • Asparagus0.3%The flourish that gives the recipe its name.
  • Glucosamine, methylsulfonylmethane, chondroitin sulphate170, 170 and 125 mg/kgPrinted doses let you compare one bag against another.
  • FOS, MOS96 and 24 mg/kgPrebiotic fibres for the bacteria in the large intestine.

Cost per day, 15kg dog
£1.01

A large breed dog eats well beyond the 15kg daily figure, so scale up from the maker's chart.

Middle of the market for a dry food, though you pay a little more than the analysis alone would justify.
