How does AIScored compare grain-free dog food?

1. Aggregate Reviews

We collect currently available review and product data from public sources to build a complete comparison baseline.

2. Analysis

We read every review, check ingredient labels, fillers, and certifications, then generate an unbiased summary.

3. Score & Rank

Products are scored 0-100 across evidence-based categories, making it easy to compare at a glance.

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.

Frequently Asked Questions

Where do you get your reviews?

We aggregate publicly available review and product data from retailer pages, communities, and specialist sources. We do not use manufacturer-provided testimonials as evidence.

How often are scores updated?

We re-analyse reviews and update scores regularly. Product pages show the date of the latest analysis.

Do you receive products for free?

No. AIScored does not accept free products or sponsored placements. Our revenue comes from affiliate links, which do not influence our scores.
