Wainwright's Large Breed Mature Dry Food review
A turkey and rice kibble for big dogs past their prime, and a Good one. Fat is pulled back to 9.0% while protein holds at 25.0%. Glucosamine, chondroitin and taurine are all printed with figures against them.
Our view
Likely to suit
- Large breeds in their later years, the size and stage the bag is written for
- An older dog whose weight has crept up. Fat sits at 9.0% with protein still at 25.0%
- Slower digestion: beet pulp at 6% takes crude fibre to 3.8%
- Ageing joints, with glucosamine at 0.05% and chondroitin at 0.015% on the label
- Homes keeping to one animal, as turkey is the only species listed
Worth watching
- Rice and barley throughout, and barley carries gluten
- Carbohydrate estimated at 50.2% of dry matter, a fair share of the bowl for a dog losing muscle
- A calculated energy figure, so weigh the first week's portions and adjust

The score, in context
- Wainwright's Large Breed Mature Dry Food 59.8
All one Good. Typical dry food: Good.
A sensible senior food that runs leaner than most of the shelf and says exactly what it contains.
What's in it
- Turkey: dried turkey, freshly prepared turkey33% (28% dried, 5% fresh)Mostly dried, which is the share that actually arrives in the bowl. Lean, easy to digest and palatable for an older appetite.
- Rice26%
- Whole grain barley, whole ground oats21%, 4.5%Whole grains keep more fibre and micronutrients. Barley carries gluten.
- Beet pulp6%A generous inclusion of both soluble and insoluble fibre, the quiet story on this label.
- Rapeseed oilThe added fat, keeping the recipe to one animal.
- Dried peas3%Equivalent to 12.5% peas.
- Linseed2%Plant omega 3. No fish anywhere on the label.
- Dried carrots, seaweed1%, 0.2%Seaweed brings iodine.
- Glucosamine, yucca extract, chondroitin0.05%, 0.02%, 0.015%The joint pair is dosed on the label. Evidence is mixed, so read it as steady daily support.
Vitamins A, D3 and E with taurine at 1000mg, which matters more in big, ageing breeds, plus trace minerals as sulphates and an oxide.
Trace minerals come as sulphates and oxide forms, not the chelates usually chosen for absorption.
Named ingredients
Against the range
One turkey recipe, on rice and whole grain barley. Every added nutrient carries a dose, from vitamin E at 150mg down to selenium at 0.1mg, and the trace minerals come as sulphates and oxides.

- A 15kg dog eats (our estimate)
- 200 to 240 g a day, 220 in the middle
- Cost per day, 15kg dog
- £0.73
A large senior eats far more than the 220g a day of a 15 kg dog: the bag asks 300 to 465 grams at 25kg to 45kg.
Budget end of the market for a dry food, though the analysis is fairly modest for what you pay.
