Supermarket Dog Food: Label Patterns to Watch
PetFoodFix content is educational and does not diagnose or treat illness. If your dog is unwell, has a diagnosed condition, is under 12 months old, is pregnant or lactating, is on a prescription diet or chronic medication, or has vomiting, diarrhoea, blood in stool, collapse, severe pain, breathing difficulty, refusal to eat for more than 24 hours, marked weight loss, severe itching, or suspected poisoning, contact your vet before changing food.
Supermarket dog food in the UK
The majority of dog food sold in the UK is purchased from supermarkets. Tesco, Sainsbury's, Asda, Morrisons, Aldi, and Lidl between them account for a significant share of the pet food market.
Supermarket shelves typically carry a range from own-brand economy lines to premium branded products. The price difference can be significant — but so can the label differences.
This guide is not about declaring one brand better than another. It is about recognising label patterns that help you make an informed comparison when standing in the aisle.
Pattern 1: "Meat and animal derivatives" as the first ingredient
Many economy and mid-range supermarket dog foods list "meat and animal derivatives" as the first or second ingredient. As explained in our ingredients guide, this is a legally permitted category name that hides the specific animal, parts, and proportions used.
What to watch: If this is the first ingredient and no further detail is given, you have minimal visibility into the primary protein source.
What to look for instead: Foods listing a named animal protein first — even at a lower price point, some supermarket ranges have started naming proteins more specifically.
Pattern 2: The "with" claim and the 4% rule
A common front-of-pack pattern in supermarket dog food is the "with" claim:
- "With chicken" = minimum 4% chicken
- "Rich in chicken" = minimum 14% chicken
- "Chicken dinner/recipe" = minimum 26% chicken
- "Chicken" (as the product name) = minimum 65% chicken
Many shoppers assume "with chicken" means the food is primarily chicken. In reality, it means at least 4% — the rest could be any other animal source under the "meat and animal derivatives" umbrella.
What to watch: Read the ingredient list, not just the front of the pack. The front is marketing; the back is regulated.
Pattern 3: Artificial colours in budget ranges
Artificial colours (E102, E110, E129) are more commonly found in budget supermarket ranges, particularly in semi-moist formats and multi-coloured kibble. The colours create the appearance of "chunks in gravy" or "meaty pieces" but serve no nutritional function.
What to watch: Multi-coloured kibble or pieces in unnaturally vibrant colours. Check the ingredient list for E-numbers in the 100 range.
What to look for instead: Single-colour kibble or foods listing "no artificial colours" on the back panel (not just the front).
Pattern 4: Cereals as the dominant ingredient
Some supermarket foods list "cereals" as the first ingredient — meaning grain makes up the largest proportion by weight. This is not necessarily harmful, but it means the food is grain-heavy rather than protein-led.
What to watch: "Cereals" without specification (could be wheat, maize, rice, or a mixture). Specified grains (e.g., "rice (14%)") are more transparent.
What to look for instead: Foods where a named animal protein appears first, with any grains named and appearing later in the list.
Pattern 5: "Premium" labels without premium ingredients
The word "premium" is not regulated in pet food labelling. Any food can call itself premium regardless of ingredient quality. The same applies to "gourmet," "natural," "holistic," and similar marketing terms.
What to watch: Front-of-pack aspirational language that is not reflected in the ingredient list on the back.
What to look for instead: Specific, verifiable claims: named proteins with percentages, "no artificial colours," "single protein source." These are either true or false — they can be checked.
Pattern 6: Own-brand ranges can surprise you
Some supermarket own-brand ranges have improved significantly in recent years. Mid-tier and premium own-brand lines from major UK supermarkets sometimes offer:
- Named protein sources with percentages
- No artificial colours or preservatives
- Competitive analytical constituent profiles
The own-brand premium range at £1.50 per pouch may have a clearer label than a branded product at £2.00. Price and brand recognition are not reliable indicators of label quality.
Pattern 7: Feeding guides vary widely
Feeding guides on supermarket dog food can differ significantly between brands for the same dog weight. This is partly because calorie density varies and partly because some brands are more generous with their recommendations.
What to watch: If two foods recommend very different portions for a 10kg dog (e.g., 100g vs 180g), the calorie density is likely very different. The food recommending smaller portions is usually more calorie-dense.
How to compare on the shelf
When standing in the supermarket, you can make a quick comparison by checking three things:
- First three ingredients — Are proteins named? Are percentages shown?
- Artificial colours — Any E102, E110, E129 listed?
- Complete or complementary — Is this a full meal or a topper?
These three checks take 30 seconds and tell you more than any front-of-pack marketing.
