Best Dog Foods With Salmon Oil UK | 9 Highest Salmon Oil Dog Food Recipes For 2026

At WeWalkWoofs, we wanted a round-up of UK dog foods that actually name salmon oil as an ingredient, not just "salmon" or "fish" listed as the protein. Salmon oil is added specifically as a concentrated source of EPA/DHA omega-3s, on top of whatever whole fish is already in the recipe, and that's the detail we found most "salmon oil dog food" round-ups gloss over. Many owners look for salmon oil specifically because it's a natural source of long-chain omega-3 fatty acids such as EPA and DHA, which contribute to maintaining healthy skin, coat, joints and cognitive function especially in older dogs.
This is a roundup of the foods with the highest declared salmon-oil percentage we could verify, not necessarily the best dog foods overall. We analysed current UK ingredient panels to identify dog foods that actually declare salmon oil as an ingredient, then ranked them by declared salmon-oil percentage, documenting conflicting manufacturer and retailer data where we found it.
🐟 Pros & Cons of Salmon Oil for Dogs 🐟
Pros:
✅ Skin & coat health
✅ Joint/anti-inflammatory support
✅ Heart health
✅ Brain & eye development (puppies)
✅ Cognitive support (seniors)
✅ Immune support
✅ Palatable, dogs like it
Cons:
❌ Calorie-dense, can cause weight gain
❌ Digestive upset if overdone
❌ Mild blood-thinning risk
❌ Pancreatitis risk in prone dogs
❌ Oxidises/goes rancid once opened
❌ Sourcing/quality varies
❌ Not a substitute for vet treatment
Quick Answer if You Are In a Hurry: If you're simply looking for the highest declared salmon-oil percentage, Vet's Kitchen Sensitive Care Salmon & Sweet Potato (9%) topped our research, followed by Wainwright's Sensitive Adult Salmon (8%) and Millies Wolfheart Salmon & Veg (5%). Salmon-oil percentage alone doesn't determine overall nutritional quality, which is why this article focuses specifically on declared salmon-oil percentage rather than overall diet quality, see the table and caveats below before choosing on percentage alone. |

Foods with the same declared salmon-oil percentage (AATU and Barking Heads, both 4%) were separated using total declared salmon content as a tie-breaker.
Important: the percentages above are printed ingredient inclusion rates, as labelled. Dry and wet foods have very different moisture content and feeding amounts, so a dry food's percentage isn't directly comparable, meal for meal, to a wet food's, neither figure tells you how much EPA/DHA a dog actually receives per day. That's why the wet pick is kept separate rather than ranked into the same list.
Pricing is indicative RRP at the time we checked (July 2026) confirm current price and subscription discounts via the links below.
Ranked Adult Dry Foods by Declared Salmon-Oil Percentage
1. Vet's Kitchen Sensitive Care Grain Free Salmon & Sweet Potato - 9% Salmon Oil Content
Ingredients: Salmon 40% (Dried Salmon 21%, Freshly Prepared Salmon 9%, Salmon Oil 9%, Salmon Gravy 1%), Sweet Potato, Peas, Potato, Beet Pulp, Lucerne, Chicory Pulp, glucosamine, MSM, chondroitin.
✅ Pros: The highest declared salmon oil percentage we identified formulated with in house vet and nutritionist input. Single named protein source & grain-free.
❌ Cons: With oil inclusion this high, portioning matters more than with a standard kibble.
💷 Pricing: 15kg (2x 7.5kg) around £45–£55 via pet retailers and Ocado.
🔍 Summary: The highest declared salmon-oil percentage we identified, making it an obvious starting point for owners specifically looking for foods with a high declared salmon oil percentage.
2. Wainwright's Sensitive Adult Dry Dog Food, Salmon With Superfoods - 8% Salmon Oil Content
Ingredients: Salmon 55% (Freshly Prepared Scottish Salmon 30%, Salmon Meal 22%, Salmon Digest 3%), Sweet Potato (26%), Salmon Oil (8%), Beet Pulp (8%), Krill Meal (0.9%), Seaweed Meal, Chicory Root Extract, Green Lipped Mussel Extract, Yucca Extract.
✅ Pros: Second highest declared salmon oil percentage we found with very high total salmon content (55%), a single source protein and one of the more affordable high salmon oil dry foods we found.
❌ Cons: Own brand formulations change more often than named brands, so it's worth rechecking the panel each purchase. There's also a naming inconsistency worth knowing about as the current product page says "Scottish Salmon," while the URL still reads "Atlantic Salmon", same product, not two different recipes. Worth noting too that "Sensitive" is the brand's own positioning rather than a clinical claim.
💷 Pricing: £12.79 for 2kg, £54.99 for 12kg at Pets at Home (checked July 2026).
🔍 Summary: Widely accessible through Pets at Home stores and its website, and a genuinely strong recipe by declared oil content.

3. Millies Wolfheart Salmon & Veg - 5% Salmon Oil Content
Ingredients: Freshly Prepared Salmon (46%), Dried Salmon (18%), Potato (7%), Sweet Potato, Tapioca, Chickpeas, Salmon Oil (5%), Pea Fibre, Lucerne, Salmon Gravy (1%), joint pack (glucosamine, MSM, chondroitin), mixed herbs.
✅ Pros: One of the highest total salmon formulations on this list, combining 64% fresh and dried salmon with 5% salmon oil and 1% salmon "gravy". It also excludes several common allergens including chicken, egg, rice and gluten containing grains. Also includes a joint-support blend (glucosamine, MSM and chondroitin), which isn't in most of the recipes further down this list.
❌ Cons: Premium price point, and available through mail order or specialist stockists only rather than supermarkets. It's also worth being precise about the allergen claim: excluding common allergens like chicken, egg and rice reduces the risk of a reaction to those specific ingredients, but that's not the same as the food being hypoallergenic outright.
💷 Pricing: ~£30–£33 for 5kg; 14–14.5kg bags typically £75–£85.
🔍 Summary: A strong, clearly labelled salmon forward recipe.
4. AATU Salmon Dry Dog Food - 4% Salmon Oil Content
Ingredients (Pets at Home listing): 80% Salmon (61% Freshly Prepared Salmon, 17% Dried Salmon, 2% Freshly Prepared Salmon Gravy), Peas (5%), Tapioca, Salmon Oil (4%), Apple (2%), Chickpeas, Sweet Potato, Sunflower Oil, Minerals, fruit and herb mix, glucosamine, MSM, chondroitin.
✅ Pros: It has the highest total declared salmon content of anything on this list, at 80%. The recipe also includes pre and probiotics, is widely stocked and available through Pets at Home, VioVet and others.
❌ Cons: There's a discrepancy here worth flagging: AATU's own product page (aatu.co.uk) lists "Salmon Oil" without a percentage, and breaks the salmon content down differently (64% salmon, 16% dried salmon), while Pets at Home's composition panel for the same product states 4% salmon oil within an 80% total split as 61%/17%/2%. We've provisionally gone with the Pets at Home figure since it's the one with an explicit percentage, but we'd recommend checking the current physical packaging before relying on it as packaging is the legal source of truth if the two disagree. It's also a premium priced recipe relative to most of this list.
💷 Pricing: £19.19–£51.59 for 1.5kg–5kg at Pets at Home; £23.99–£99.99 for 1.5kg–10kg direct from AATU.
🔍 Summary: The highest total salmon recipe here, tied with Barking Heads on declared salmon oil
percentage but ranked above it on total salmon content.

5. Barking Heads All Hounder Hair Necessities Salmon - 4% Salmon Oil Content
Ingredients: Salmon 50% (Freshly Prepared Scottish Salmon 26%, Dried Salmon 20%, Salmon Oil 4%), Sweet Potato (26%), Potato, Peas (10%), Lucerne, Minerals, yeast products, chicory root extract, seaweed, mixed herbs.
✅ Pros: The percentage is clearly disclosed and consistent across every source we checked. It's widely stocked too as Pets at Home, Amazon and Zooplus all carry it. The recipe is grain free with a joint support blend included.
❌ Cons: Worth noting that Barking Heads also sells a separate wet recipe, Pooched Salmon (made with salmon and sardine). It's a different product from this dry recipe, not an alternative format of it. The "vet-approved" claim on pack is the brand's own description; we didn't find it tied to any independent certification scheme.
💷 Pricing: 12kg bag around £45–£55; smaller bags scaled accordingly.
🔍 Summary: Well known, easy to find, and one of the more consistently labelled recipes on this list.
6. Harringtons Just 6 Salmon & Vegetables - 2.5% Salmon Oil Content
Ingredients: Salmon 50.5% (Freshly Prepared Salmon 23%, Dried Salmon 23%, Freshly Prepared Salmon Oil 2.5%, Freshly Prepared Salmon Jus 2%), Dried Potato (19%), Sweet Potato (17%), Peas (11.5%), Rapeseed Oil (1%), Vitamins & Minerals.
✅ Pros: Marketed around six core ingredients, with added vitamins, minerals and rapeseed oil. It's over 50% salmon with a disclosed 2.5% salmon oil, and it's widely available and competitively priced for the salmon percentage it carries.
❌ Cons: Worth noting Harringtons also sells a lower salmon dry recipe, "Rich in Salmon & Potato" (26% salmon and meat meals, 1% salmon oil), alongside this one. Easy to grab the wrong bag by mistake! Just 6 itself doesn't include a joint support blend or probiotics, unlike some of the recipes above it on this list.
💷 Pricing: 2kg around £6–£8; 12kg typically £30–£38.
🔍 Summary: A genuinely good mid-price option once you're buying the right recipe as Harringtons runs several salmon products side by side under similar branding, and they're not interchangeable.
7. Pooch & Mutt Health & Digestion Salmon - 1.5% Salmon Oil Content
Ingredients: Fresh Salmon (25%), Sweet Potato (22%), Salmon Protein (16.2%), Potatoes, Peas, Salmon Oil (1.5%), Salmon Gravy, Alfalfa, Beet Pulp, Linseed, probiotics, psyllium husk.
✅ Pros: Purpose built for digestive sensitivity rather than just skin and coat, with added probiotics and psyllium. It's grain, gluten and cereal free, and first orders often come with a subscription discount of 30% or more..
❌ Cons: Salmon oil percentage is modest next to the entries above it, and it's only sold direct through the brand's own website rather than via retailers, so there's less room to shop around on price.
💷 Pricing: From roughly £10.38/month for a 0–5kg dog on subscription, scaling to ~£49/month for 25–50kg dogs.
🔍 Summary: Best understood as a gut-health-first recipe that happens to carry salmon oil, rather than a recipe built around omega-3 density specifically.
8. Forthglade Cold Pressed Salmon - 1% Salmon Oil Content
Ingredients: Salmon (29.5%: fresh + dried ground salmon), Dried Sweet Potato, Dried Peas, Beet Pulp, dried fruit, Sunflower Oil (1.5%), Salmon Oil (1%), botanicals, glucosamine, chondroitin.
✅ Pros: It's cold-pressed at low temperature and Forthglade's argument is that this preserves more nutrients than standard extrusion (the high-heat process most dry kibble goes through). We'd treat that as the brand's own case rather than settled science as we found the same claim across most cold pressed brands' own marketing, but no independent research backing it either way.
❌ Cons: Salmon oil is 1% , lower than most entries above it · short shelf life once opened (one month).
💷 Pricing: £16.00 for 2kg, £47.99 for 6kg, £89.99 for 12kg, £125.99 for 18kg.
🔍 Summary: A well-reviewed all-rounder from a recognisable natural food brand, though its salmon oil content specifically sits toward the lower end of this list.
9. Tribal Fresh-Pressed Adult Salmon - 0.5% Salmon Oil Content
Ingredients: Fresh Salmon (35%), Sweet Potato (35%), Blue Whiting (hydrolysed, 10%), Whole Egg (8%), Beet Pulp, Brewer's Yeast, Sunflower Oil (1.6%), Salmon Oil (0.5%), herbal blend, glucosamine, green-lipped mussel, chondroitin.
✅ Pros: No meat meal — fresh salmon and whole egg rather than rendered protein · herbal blend and green-lipped mussel · UK small-batch production.
❌ Cons: Salmon oil inclusion is the lowest on this list · less brand recognition than Forthglade in the same category.
💷 Pricing: 2.5kg and 12kg bags, broadly comparable to Forthglade's cold-pressed range per kg.
🔍 Summary: A credible fresh-meat, no-meal cold-pressed option, though salmon oil is a supporting ingredient rather than the headline here.

Wet food picks
Harringtons Salmon & Potato with Vegetables (Wet Trays) - 0.4% Salmon Oil Content
Ingredients: Salmon & Chicken 65% (26% Freshly Prepared Salmon), Vegetables 14% (Potato, Peas, Carrot), Vitamins & Minerals, Salmon Oil (0.4%), Sunflower Oil, Dried Tomato, Seaweed, Green Lipped Mussel, Chicory, Parsley, Basil, Green Tea, Rosemary, Rosehip.
✅ Pros: Widely available in supermarkets (Tesco, Asda, Morrisons), cheap relative to other wet foods here · salmon oil addition is explicitly labelled for skin/coat · easy to use as a topper.
❌ Cons: A salmon-and-chicken recipe, not single-protein salmon — worth knowing if chicken needs excluding · overall meat/fish specification is less detailed than premium brands · wet food cost-per-day is higher than dry if used as a sole diet.
Pricing: 8 x 400g trays typically £6–£9 depending on retailer/offer.
Summary: The most accessible, cheapest entry on this list. This wet recipe isn't directly comparable to the dry-food rankings above.
What matters to you?
Salmon-oil percentage is one metric, not the whole decision. If a different priority matters more, here's where we'd point you instead:
What matters to you | Best choice |
Highest declared salmon oil | Vet's Kitchen Sensitive Care |
Best value for the oil content | Wainwright's Sensitive Adult Salmon |
Highest total salmon content | AATU Salmon |
Best budget option | Harringtons Just 6 Salmon & Vegetables |
Best cold-pressed recipe | Forthglade Cold Pressed Salmon |
Best for digestive sensitivity | Pooch & Mutt Health & Digestion |
Puppy picks (not ranked against the adult list)
Lily's Kitchen Chicken & Salmon (Puppy Dry)
Ingredients: Fresh Chicken (27%), Freshly Prepared Salmon (10%), Chicken Liver (7%), Sweet Potatoes, Pea Protein, Chicken Fat, Egg, Flaxseed, Salmon Oil (% undisclosed), Joint Care Mix, prebiotics, carrots, apples, cranberries, spinach.
Chicken-led, not salmon-led — salmon is the secondary protein. Lily's Kitchen also sells an adult salmon dry food (40% freshly prepared salmon, named salmon oil) that's more directly relevant for an adult, salmon-first brief. Pricing: from £10.50 for 1kg up to £97 for 12kg.
Wainwright's Sensitive Wet Puppy Food Atlantic Salmon with Superfoods — 0.3%
Ingredients: Salmon (70%), Dehydrated Sweet Potato, Dehydrated Peas, Krill Meal (1%), Minerals, Salmon Oil (0.3%), Dried Seaweed, Green Lipped Mussel, Chicory Root Extract, Yucca Extract.
High total salmon content (70%) for a wet food; the omega-3 story here rests more on whole salmon than added oil. Cheapest access point on this list. Pricing: typically £1–£2 per single tray, cheaper in multipacks.
Contains salmon oil, percentage undisclosed
Burns Original Fish & Brown Rice (Dry) — Brown Rice (61%), Fish Meal (20%), Oat Flakes, Peas, Salmon Oil, Sunflower Oil, Seaweed, Minerals.
Developed by vet John Burns; long-established brand (since 1993). Rice-led recipe means lower overall animal protein than the salmon-first recipes above. We can confirm the brand's veterinary founder and long track record; we can't verify "widely trusted by vets" as an independent claim, so we've left it out. Typically £15–£45 depending on size. Unlike AATU, we found no retailer listing that discloses a percentage for this one, from either manufacturer or retailer sources.
How we researched this
We went to the source for each brand: the manufacturer's own product page first, then cross-checked against major UK retailers carrying the full composition panel — Zooplus, Ocado, Pets at Home, VioVet, Amazon UK. Every entry needed the literal words "Salmon Oil" in a composition list before it made the cut — not marketing copy claiming "omega-3 rich."
Our policy where manufacturer and retailer data disagree: we treat the manufacturer's own page as primary, but where a major direct retailer's own composition panel discloses a percentage the manufacturer's page doesn't, we use it and flag the discrepancy in the entry — as with AATU above — rather than silently picking one source. We haven't applied this to resellers or marketplace listings, only to primary retailers with their own product pages (Pets at Home, Ocado, Zooplus).
We rechecked this list against current manufacturer and retailer pages before publishing, which changed the shortlist twice: adding Wainwright's adult recipe (8%) after our first pass had only found their puppy food, and adding AATU (4%) after confirming Pets at Home's own panel discloses a percentage that AATU's own site currently doesn't.
Brands checked and left out because their composition shows a different added fat (sunflower or linseed oil) rather than salmon oil, even though salmon is the named protein: Skinner's Field & Trial Salmon & Rice, standard Forthglade wet trays, James Wellbeloved Fish & Vegetables, Autarky Salmon.
We didn't consider marketing claims, customer reviews or brand popularity when determining the ranking. Products were ordered using declared salmon-oil inclusion only, with transparent tie-breakers where necessary.
Limitations of this research
Ingredient formulations can change without notice, and a brand's own page can lag behind what's on the current physical bag (see the AATU entry above).
Some brands don't publish a salmon-oil percentage at all — we've listed those separately rather than guessing.
Declared ingredient percentages don't reveal EPA/DHA content, which can vary by oil source and isn't published separately by most brands here.
Wet and dry foods can't be compared directly by ingredient percentage, due to moisture content and different feeding amounts.
Prices are same-day snapshots and should be rechecked before purchase or before linking out.
Notes on methodology
All ingredient panels are taken from manufacturer or major UK retailer product pages as listed at the time we researched this.
Prices fluctuate with retailer promotions and subscription discounts — treat the figures above as a same-day snapshot rather than fixed RRP, and verify again before publishing or linking out.
Declared ingredient percentages are shown as printed by each manufacturer or retailer and should not be read as a direct measure of daily EPA/DHA intake, particularly across wet and dry formats.
