# Best Grain Free Dog Food 2026: 10 Ranked by Cost per Kilo Source: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food Published: 2026-09-16 | Updated: 2026-09-16 | Prices checked on Amazon UK on 2026-09-16 Ten bags of grain free dog food, ten ratings packed between 4.4 and 4.8 stars — and a price spread that no star rating explains. Alpha's 15kg sack costs £29.79, which is £1.99 a kilo. James Wellbeloved's 7.5kg bag costs £49.63, which is £6.62 a kilo. That is 3.3 times the price inside the same half-star band. Meanwhile the listings argue with themselves. Pooch & Mutt prints 'made in the UK' in its highlights and 'China' as the country of origin. Autarky's white fish and potato recipe is filed under 'Plant-Based'. In short, the cheapest bag of grain free dry dog food here is not the worst one. We ranked ten of the best grain free dog food options on Amazon on three things you can check yourself: price per kilo, the protein and ingredient claims in the spec table, and whether the listing's own numbers agree with each other. Star ratings we treated as background noise. ## The ranking ### 1. Pooch & Mutt Health & Digestion Grain Free Salmon & Sweet Potato 10kg - Price: £47.50 | Amazon rating: 4.7 from 919 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/pooch-mutt-health-digestion - Buy on Amazon: https://www.amazon.co.uk/dp/B009P2ZDFG?tag=ranked10-21 Top of the list on 919 ratings and a 4.7 average, with 45% salmon as the only animal protein — though the same listing says 'made in the UK' and 'China'. 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. Pros: 4.7 average from 919 ratings — the largest review base in this group; 45% salmon as the only animal protein source; £4.75 a kilo on a 10kg sack; Free from grain, cereal, gluten, GM ingredients and artificial colours; Prebiotics listed to support gut bacteria Cons: £47.50 for 10kg is 2.4 times the £1.99 a kilo of the Alpha sack; Highlights say 'made in the UK' while the country of origin says 'China'; Container type is listed as a 'Pouch' on a 10kg dry food; An expensive way to feed a large dog ### 2. Skinner's Field & Trial Grain Free Chicken & Sweet Potato 15kg - Price: £43.04 | Amazon rating: 4.6 from 621 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/skinners-grain-free-chicken-15kg - Buy on Amazon: https://www.amazon.co.uk/dp/B07DCNWL6R?tag=ranked10-21 Second-lowest cost per kilo in the group at £2.87, backed by 621 ratings and a mill in Suffolk that has been in one family for seven generations. 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. Pros: £43.04 for 15kg, or £2.87 a kilo — the second-lowest here; 4.6 average from 621 ratings; Formulated without wheat, maize, barley or oats; Milled at Stradbroke Mill in Suffolk by the same family for seven generations; No artificial colouring, flavours or preservatives added Cons: Chicken is the main protein, so it is unsuitable for poultry sensitivities; No chicken percentage given anywhere on the listing; Spec fields list 'Boxer' as the breed and 'Birthday' as the occasion; A 15kg sack needs serious storage space ### 3. Harringtons Just 6 Grain Free Chicken & Salmon Dry Dog Food 12kg - Price: £52.99 | Amazon rating: 4.6 from 231 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/harringtons-just-6-chicken-12kg - Buy on Amazon: https://www.amazon.co.uk/dp/B0B4DYGWN9?tag=ranked10-21 A 4.6 average from 231 ratings, but £52.99 for 12kg is £4.42 a kilo — half again the Skinner's sack for a shorter ingredient list. 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. Pros: 4.6 average from 231 ratings; Over 50% chicken and salmon by its own claim; Grain-free recipe aimed at food sensitivities; Made by Inspired Pet Nutrition with a North Yorkshire contact address; Wheat-free as declared on the allergen line Cons: £4.42 a kilo — more than 50% above the Skinner's sack; 'Just 6' ingredients, yet chicken appears as fresh chicken, salmon oil and chicken gravy; Allergen information says 'Wheat Free', not 'grain free'; Flavour field reads 'Chicken' while the bullets promise chicken and salmon ### 4. Crave Turkey & Chicken Grain Free Dry Adult Dog Food 7kg - Price: £40.00 | Amazon rating: 4.8 from 327 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/crave-turkey-chicken-7kg - Buy on Amazon: https://www.amazon.co.uk/dp/B09TMJNGQ9?tag=ranked10-21 The joint-highest score here at 4.8 from 327 ratings, held back by £5.71 a kilo and a spec table that calls a dry kibble 'Raw'. 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. Pros: 4.8 average from 327 ratings, with 85% five-star; £5.71 a kilo on a 7kg bag; No maize, wheat, soya or dairy; High-protein recipe for muscle support; Made in Germany by Mars Petcare Cons: £40 for 7kg — 2.9 times the cost per kilo of the Alpha sack; Diet type listed as 'Raw' on a dry kibble; Two animal proteins, so not a single-source option; Packaging may differ from the photograph ### 5. James Wellbeloved Grain Free Turkey Dog Food 7.5kg, Small Breed - Price: £49.63 | Amazon rating: 4.8 from 62 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/james-wellbeloved-small-breed-turkey - Buy on Amazon: https://www.amazon.co.uk/dp/B0DQV4B1PF?tag=ranked10-21 The second-dearest bag per kilo at £6.62, with the smallest review sample in the top five at 62 ratings. 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. Pros: Excludes beef, pork, soya, eggs, dairy and wheat; Smaller kibble cut for a small breed's mouth; Prebiotics and fibres listed for digestion; Vitamin E and minerals for immune support; Grain-free turkey recipe Cons: £6.62 a kilo — the second-highest here; Only 62 ratings, so the 4.8 rests on a small sample; Breed recommendation says 'All Breed Sizes' while dog breed size says 'Small'; 7.5kg will not last long in a medium or large dog ### 6. Autarky Grain Free White Fish & Potato Dry Dog Food 12kg - Price: £35.99 | Amazon rating: 4.4 from 595 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/autarky-grain-free-white-fish - Buy on Amazon: https://www.amazon.co.uk/dp/B01FWJWT6Q?tag=ranked10-21 Third-cheapest at £3.00 a kilo with 595 ratings, but this hypoallergenic grain free dog food is filed as 'Plant-Based' with white fish as the first ingredient. 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. Pros: £3.00 a kilo on a 12kg sack — third-cheapest here; 595 ratings at 4.4; Joint package: green lipped mussel, glucosamine, olive extract, marine algae; 27% protein and 13% fat; Wheat gluten and soya free Cons: Diet type is listed as 'Plant-Based' on a white fish recipe; Country of origin is listed as China; 10 of 595 ratings are one or two stars; Lowest average score of the top six ### 7. Burns Grain Free Duck & Potato Dry Dog Food 2kg - Price: £13.69 | Amazon rating: 4.4 from 114 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/burns-grain-free-duck-potato - Buy on Amazon: https://www.amazon.co.uk/dp/B0DYL1899Z?tag=ranked10-21 The dearest bag per kilo here at £6.85, on a 2kg sack listed in Amazon's Freeze-Dried Dog Food category despite being a dry granule. 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. Pros: Single-source duck protein; Taurine added for heart health; Hypoallergenic, limited-ingredient recipe; 4.4 from 114 ratings; Suitable for adult and senior dogs Cons: £6.85 a kilo — the most expensive per kilo here; 2kg bag only, so a large dog empties it quickly; 10 of 114 ratings are one star; Listed in the Freeze-Dried Dog Food category despite being a dry granule ### 8. Edgard & Cooper Grain Free Venison & Duck Dry Dog Food 2.5kg - Price: £15.00 | Amazon rating: 4.4 from 635 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/edgard-cooper-venison-duck-dry - Buy on Amazon: https://www.amazon.co.uk/dp/B07H3YKXCZ?tag=ranked10-21 A 4.4 average from 635 ratings and fresh venison rather than meat meal, at £6.00 a kilo. 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. Pros: 4.4 average from 635 ratings; Fresh venison and duck, no meat meal; Made in Belgium; GMO free with a prebiotic for digestion; Grain-free and gluten-free Cons: £6.00 a kilo on a 2.5kg bag; Novel proteins are not automatically hypoallergenic; Bullet copy is written in a chatty style that adds no feeding information; 2.5kg is a short supply for a large breed ### 9. Eukanuba Grain Free Venison Complete Dry Dog Food 3kg - Price: £16.99 | Amazon rating: 4.7 from 97 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/eukanuba-grain-free-venison-3kg - Buy on Amazon: https://www.amazon.co.uk/dp/B0FTGD9MXD?tag=ranked10-21 4.7 from 97 ratings and £5.66 a kilo, with a dental claim that rests on kibble shape rather than nutrition. 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. Pros: 4.7 from 97 ratings; £5.66 a kilo on a 3kg bag; Prebiotic FOS and beet pulp for digestion; Omega-3 and 6 for skin and coat; Kibble shape built around DentaDefense minerals for teeth Cons: Listed as a 'Veterinary Diet' with no vet authorisation mentioned; No venison percentage stated anywhere on the listing; 3kg bag only, so the per-kilo cost holds for a large dog; 8 of 97 ratings are three stars ### 10. Alpha Grain Free Working Dry Dog Food Chicken 15kg - Price: £29.79 | Amazon rating: 4.4 from 83 ratings - Full review: https://www.ranked10.co.uk/pet-supplies/best-grain-free-dog-food/alpha-grain-free-working-15kg - Buy on Amazon: https://www.amazon.co.uk/dp/B07SB8VTNF?tag=ranked10-21 The cheapest grain free dog food here: £29.79 for 15kg is £1.99 a kilo, on the smallest review base in the group. Alpha is last on the list, not on price. £29.79 for 15kg is £1.99 a kilo — the cheapest grain free dog food here by a clear margin, and 3.4 times cheaper per kilo than the Burns bag. The recipe is chicken, potato and vegetables at 25% protein, with prebiotics from chicory root and mannan-oligosaccharides, linseed for skin and coat, and yucca extract. It is sold for working, active and sporting dogs, with a contact address in Lincolnshire, and it is a grain free dry dog food rather than a grain-free-labelled treat. The honest caveat is the review base: 83 ratings is the smallest sample here, so its 4.4 carries less weight than the 4.7 from 919 ratings on the Pooch & Mutt bag. Two of the five bullets are word-for-word duplicates, which tells you the listing was not proofread. And a 15kg sack is a lot of cupboard space. Pros: £1.99 a kilo on a 15kg sack — the lowest here; 25% protein with prebiotics from chicory root and MOS; Linseed included for skin and coat; No artificial colours or flavours; 15kg covers a large dog for a long stretch Cons: Only 83 ratings — the smallest sample in this group; Two of the five bullets are word-for-word duplicates; Formulated for working and active dogs rather than couch dogs; A 15kg sack takes up serious storage space ## Verdict For most homes, the Skinner's 15kg at £2.87 a kilo is the sensible buy: a 4.6 average from 621 ratings and the second-lowest price per kilo in this group of grain free dog food. If cost decides it, the Alpha 15kg at £1.99 a kilo is the cheapest grain free dog food on the list, though its 83 ratings are a thin base to lean on. If your dog has a genuinely sensitive stomach and you want a long, readable label, the Pooch & Mutt at £4.75 a kilo has 919 ratings behind it — and a listing that contradicts itself on where it was made. Either way, ignore the half-star gaps and work out the price per kilo before you buy.
