Best Grain Free Dog Food 2026: 10 Ranked by Cost per Kilo

Pooch & Mutt sits first because it has by far the deepest review base here: 4.7 stars from 919 ratings, against 83 for the Alpha sack and 62 for the James Wellbeloved bag. The recipe rests on one animal protein, at 45% salmon, plus sweet potato and pumpkin. At £47.50 for 10kg it works out at £4.75 a kilo — mid-table for this group, and it is the only grain free salmon dog food on the list.

In practice the 10kg sack suits a medium or large dog, and the spec table covers all life stages and all breed sizes. Prebiotics are listed to support gut bacteria, and the recipe excludes grain, cereal, gluten, GM ingredients, artificial flavours, colours and preservatives. The kibble is the regular cut rather than a small-breed size.

That said, two fields in the same listing do not agree. The highlights say 'made in the UK'; the country of origin field says 'China'. The container type is listed as a 'Pouch' on a 10kg dry food. If a single, clearly stated origin matters to you, or if £4.75 a kilo is more than you want to spend, the Skinner's sack costs £2.87 a kilo for a similar score.

Skinner's lands second on price rather than on score. £43.04 buys 15kg, which is £2.87 a kilo — under two-thirds of the Pooch & Mutt sack and the second-lowest figure here. The 4.6 average comes from 621 ratings, the second-largest sample in the group, so the number has some weight behind it.

The recipe is formulated without wheat, maize, barley or oats, and uses chicken with linseed for skin and coat condition. It is milled at Stradbroke Mill in Suffolk, which has been in the Skinner family for seven generations and has made complete dog food since the early 1970s. The listing positions it for active and working dogs, and at 15kg it is the sort of grain free dog food for large breeds that you buy monthly rather than weekly.

However, chicken is the main protein, so it is no answer if your dog reacts to poultry, and the listing never states what percentage of the bag is chicken. The spec table recommends it for 'Boxer' and lists 'Birthday' as the occasion — filler fields, not feeding guidance. Even so, at this price per kilo the numbers are hard to argue with.

Harringtons takes third on a 4.6 average from 231 ratings, but it is not a cheap bag: £52.99 for 12kg is £4.42 a kilo, roughly 50% more per kilo than the Skinner's sack. The pitch is a short ingredient list — 'Just 6' — with over 50% chicken and salmon, cooked at lower temperatures in what the listing calls its FreshCook method.

The recipe is aimed at grain free dog food for sensitive stomachs, and the manufacturer contact address is in Thirsk, North Yorkshire. Breed size is listed as medium, the allergen line says wheat free, and the kibble is a pellet with added slow-baked bites alongside it.

The catch is that the 'Just 6' claim and the spec table pull in different directions. The chicken appears three times on the special ingredients line: freshly prepared chicken, salmon oil and chicken gravy. The declared allergen information is 'Wheat Free', which is not the same claim as grain free. Which means the headline promise is simpler than the detail underneath it.

Crave has the joint-highest score in the group, 4.8 from 327 ratings, and 85% of those are five stars. What the score does not tell you is the price: £40 for a 7kg bag is £5.71 a kilo, nearly three times the Alpha sack.

By contrast with the cheaper bags, the spec sheet is mostly clean: no maize, wheat, soya or dairy, high protein for muscle support, and a country of origin of Germany under Mars Petcare. This is a grain free turkey dog food in name, though the bag also lists chicken, and the bullets promise '100% Natural Chicken' and 'fresh Chicken' in the same breath.

Worth noting: the diet type field says 'Raw' on a product that is plainly a dry kibble, and the packaging may differ from the photograph. If you feed a large dog, or you want one protein and nothing else, this is not the bag to pick.

James Wellbeloved also scores 4.8, but from 62 ratings rather than 327 — a sample small enough that a handful of reviews moves it. On cost it is the second dearest here: £49.63 for 7.5kg is £6.62 a kilo.

The engineering is aimed at small dogs with sensitive systems. The recipe excludes beef, pork, soya, eggs, dairy and wheat, the kibble is cut smaller for a small mouth, and prebiotics and fibres are included for digestion, with vitamin E and minerals for immune support. It sits at number 293 in Amazon's Dry Dog Food ranking.

In theory that makes it a tidy choice for a small breed with a sensitive stomach. The catch is scale: 7.5kg at £6.62 a kilo disappears quickly in a medium or large dog, and the breed recommendation field says 'All Breed Sizes' while the dog breed size field says 'Small'. If you are feeding anything bigger than a spaniel, the maths goes against you.

Autarky is the third-cheapest bag here at £3.00 a kilo, and the 4.4 average is drawn from 595 ratings, the third-largest base in the group. The recipe is white fish and potato at 27% protein and 13% fat, built for working and highly active dogs.

The joint package is the reason it ranks this high: olive extract, green lipped mussel, marine algae and glucosamine, alongside zinc and B vitamins and prebiotics. It is wheat gluten and soya free, which is the practical case for buying this hypoallergenic grain free dog food.

Even so, two spec fields look wrong. The diet type is recorded as 'Plant-Based' on a recipe whose first named ingredient is white fish. The country of origin is recorded as China. And 10 of the 595 ratings are one or two stars — the widest low-score block in the top six. If you need a clearly stated origin, look elsewhere.

Burns scores 4.4 from 114 ratings, and it is the most expensive bag here per kilo: £13.69 for 2kg works out at £6.85 a kilo. That is 3.4 times the Alpha sack.

The recipe is deliberately narrow — duck, seaweed, buckwheat and potato — with a single animal protein, taurine for heart health, and a hypoallergenic, limited-ingredient build. It is aimed at adult and senior dogs of all breeds, and the packaging is being redesigned, so what arrives may not match the photo.

That said, 2kg does not go far at £6.85 a kilo, and 10 of the 114 ratings are one star, the largest one-star share in this group. The listing also places it at number 12 in Amazon's Freeze-Dried Dog Food category, despite the item form being a granule. If you feed a large dog or want the lowest cost per kilo, this is not the bag.

Edgard & Cooper has the second-largest review base in the group — 635 ratings at 4.4 — and a price of £15 for 2.5kg, which is £6.00 a kilo.

The recipe uses fresh venison and duck rather than meat meal, with fruits, vegetables and herbs, a prebiotic for digestion, and no GM ingredients. It is made in Belgium and sold in small, medium and large bag sizes, so the 2.5kg here is the entry size rather than the only option.

At the same time, £6.00 a kilo is three times the Alpha sack, and novelty proteins are not the same as hypoallergenic ones — a dog can still react to venison. The bullet copy is written in a chatty question-and-answer style that adds no feeding information. If you want the lowest cost per kilo, keep looking.

Eukanuba earns 4.7 from 97 ratings and costs £16.99 for 3kg, or £5.66 a kilo. Venison is the protein source, and the listing supports it with omega-3 and 6 for skin and coat, vitamin E for immunity, and prebiotic FOS with beet pulp for digestion.

The dental claim is the interesting one: a kibble shape paired with what Eukanuba calls DentaDefense minerals, which is a mechanical claim rather than a nutritional one. In practice the shape of the biscuit does the work. Country of origin is the Netherlands, manufacturer Spectrum Brands.

Crucially, the diet type is recorded as 'Veterinary Diet', and nothing on the listing says a vet prescribed or endorses it. The bag also never states what percentage of it is venison. If you want a stated meat percentage or a larger sack, this 3kg bag is not the one.
