WorkingHPRs Senior: Grain Free Senior review

62.9/100Good
DryAdultSenior

Three different answers to what an older dog should eat, with the trout and turkey recipes in our Good band and the white fish in Average. Each keeps the fat down and prints its joint doses on the bag. They part ways on what fills the rest: fish and sweet potato, one bird, or rice and barley.

Our view

Likely to suit

  • Older dogs with a weight to watch, with fat at 8.0% on two and 9.0% on the third
  • Stiffening joints, given printed doses of glucosamine, MSM and chondroitin on every bag
  • One named bird and nothing else, in the turkey
  • Dogs kept off cereal: two of the three build on sweet potato and potato
  • Slowing digestion, with FOS and MOS on both grain free labels
  • Lifelong cereal eaters, who will find rice, barley and oats in the white fish

Worth watching

  • Two of three fish led, so a fish-free dog wants the turkey
  • No species for the dried fish in the white fish recipe
  • Carbohydrate at 57.1% of dry matter in the white fish, against 46.2% typical
  • Pea and potato protein topping up Grain Free Senior

The score, in context
  1. Turkey 67.7
  2. Grain Free Senior 62.9
  3. White Fish 45.2

Three recipes across Good and Average. Typical dry food: Good.

The two meat-led recipes finish together and the white fish one rung lower, because it asks less of the meat; that does not make it a bad bowl for a dog raised on cereal.

What's in it
  • Trout and salmon: freshly prepared trout, dried salmon, freshly prepared salmon, salmon oil, salmon stock50%30% trout leads. Unusual in a senior food, and the 3% salmon oil is a proper marine omega 3.
  • Sweet potato24%
  • Potato, peas
  • Beet pulpFibre.
  • Pea protein, potato proteinLift the analysis without matching meat for digestibility.
  • Linseed
  • Minerals, vitamins, vegetable stock, asparagus
  • Glucosamine, methylsulfonylmethane, chondroitin sulphate170, 170, 125 mg/kgPrinted doses.
  • FOS, MOS92 mg/kg, 23 mg/kg

Vitamins A and D3 with six trace elements, each with a printed figure.

The lightest bowl of the three, for an older dog that has to lose a little.

Three senior recipes built three different ways. Grain Free Senior leads on trout and salmon at 50%, the turkey keeps to one named bird at 50%, and White Fish with Rice opens on brown rice with unnamed dried fish behind it.

All three print glucosamine and methylsulfonylmethane at 170 or 180 mg/kg and chondroitin sulphate at 125 mg/kg. Fat stays between 8.0% and 9.0%, and energy runs from 320 to 343 kcal per 100g, all below the 357 typical for adult dry food.
