What should you look for when buying grain-free dog food?
Choosing the right grain-free dog food can be overwhelming with hundreds of options on the UK market. Here are the key factors we analyse when scoring each product:
Ingredient Quality
We look at the first five ingredients, the percentage of named animal protein, and whether the recipe relies on meat meals, by-products, or fillers. Higher-quality protein sources score better.
Nutritional Profile
Protein-to-fat ratios, fibre content, and added vitamins matter. We check whether the guaranteed analysis meets FEDIAF guidelines and compare formulations across brands.
Transparency & Sourcing
Does the brand disclose where ingredients are sourced? Are country-of-origin and manufacturing details clearly stated? Brands that are transparent about their supply chain earn higher trust scores.
Value per Serving
We calculate the daily feeding cost based on recommended serving sizes and compare it against ingredient quality. Premium ingredients at a fair price score highest.
How Our Scoring Works
Each product is scored 0-100 across evidence-based categories. An overall score of 80+ indicates a product we'd recommend to most people. Scores of 60-79 are solid choices with some trade-offs, while anything below 60 has significant drawbacks reported by users. Our scores are recalculated regularly as new reviews and ingredient data come in.
