Wainwright's Grain Free Large Breed Adult Dry Food review

61.6/100Good
DryAdult

Wainwright's Grain Free Large Breed Adult is a turkey kibble sized and supplemented for big dogs. Turkey accounts for 34.5% of the recipe across four printed entries. Sweet potato at 33% does the starch and no cereal appears at all. At the bottom of the list, glucosamine, MSM and chondroitin each carry a percentage. It finishes in our Good band.

Our view

Likely to suit

Big dogs ask a great deal of their joints over a lifetime, and this recipe puts something in the bowl to acknowledge it.

  • Large breed adults, the dog this bag is portioned and built for
  • A household off cereal, since potato flake and sweet potato at 33% do the binding here
  • Owners who want joint support they can actually see, with glucosamine, MSM and chondroitin each given their own figure
  • Dogs that thrive on turkey, with the list naming no second animal
  • Households avoiding fish, because the omega 3 comes from linseed at 2% rather than from a marine oil

Worth watching

Before this becomes the regular bag, there are a handful of details to know.

  • Potato protein appears fairly high up the list, and no vegetable protein matches the turkey above it
  • The energy figure here is calculated, not declared, so weigh the first week of portions and see what the dog tells you
  • Glucosamine and MSM come in at 0.02% each with chondroitin at 0.014%, useful background and not a clinical dose
  • The trace minerals are sulphates and oxides, where a chelated form is generally better taken up

The score, in context

This one earns our Good band, level with the middle of the adult dry category. Turkey at 34.5% and protein converting to 27.5% of dry matter do most of that work, with carbohydrate at 48.9% of dry matter finishing near the 46.2% that is typical.

The pillars spread out: protein and processing and nutritional balance both read Average, value sits in Good and transparency reaches Outstanding. The label holds nothing back, even if the recipe breaks no new ground. What you are buying is a competently built grain-free kibble that names its animal, prints its splits and adds the joint ingredients a big dog has a genuine use for.

Ingredient notes

Turkey is declared in four parts: 22.5% turkey meal, 5% turkey fat, 5% freshly prepared turkey and 2% turkey digest. Protein comes mostly from the meal, since freshly prepared meat is largely water that the oven drives off. The fat brings the energy. The digest is a palatant that keeps a big dog interested in a bowl it has seen every day for years. Protein converts to 27.5% of dry matter, a solid figure for a kibble.

There is no cereal at all. Sweet potato at 33% is in front on the plant side, with potato flake binding and whole peas at 5% behind. Whole peas are the better form to see. They bring fibre and antioxidants and a spread of vitamins along with their protein, where a stripped pea protein brings only the last of those.

The joint ingredients are the reason this recipe exists as a separate bag, and all three are printed with figures: glucosamine and MSM at 0.02% each, chondroitin at 0.014%. Glucosamine and chondroitin occur naturally in animal cartilage and bone, so any meat-based food carries traces, and adding them deliberately is standard practice on large breed recipes. The clinical evidence for all three is mixed, not settled. Take them as sensible insurance for a heavy frame, not as treatment for a dog that is already sore.

Beet pulp at 3% supplies both soluble and insoluble fibre. Chicory root extract at 0.1% carries inulin. Gut bacteria in the large intestine make use of it. The omega 3 here is whole linseed at 2%. A dog is slower to turn plant omega 3 into the skin-active types than it is with fish, so a coat may take a few weeks to answer.

Carrot and seaweed at 0.5% each bring vitamin A, with iodine and a spread of other minerals. The tail of broccoli, parsley, rosehip, thyme and spearmint sits at trace level, where it does no harm and no heavy lifting. Yucca extract at 0.02% works on the smell of what the dog leaves behind, no small thing when the dog is a big one.

The added panel is dosed openly, with zinc at 100mg, iron at 60mg, manganese at 50mg, copper at 8.0mg, iodine at 2.5mg, selenium at 0.1mg and vitamin E at 150mg. Mixed tocopherols do the preserving, the natural option rather than a chemical one, which matters on a bag this size because it will be open for a while.

Price and value

£3.67 a kilo, sold in a 15kg bag.

As a guide, a 15kg dog in moderate condition would eat about 249 grams a day, assuming around 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate). That puts feeding at roughly £0.92 a day. A large breed adult eats a good deal more than that. Scale the guide up to suit your own dog, and let the waistline confirm you have it right.
