How We Score Pet Food
Our safety score uses a position-weighted formula: ingredients listed first (higher concentration) receive more weight in the calculation. Each ingredient is scored 1-10 based on published veterinary research and regulatory data. The final product score reflects the overall ingredient quality, with penalties for known carcinogens, artificial preservatives, low-quality fillers, and artificial colors.
What to Look For in Dog Food
- • Named protein first — "Chicken" or "Salmon" is better than "Meat by-products"
- • Minimal fillers — Avoid corn gluten meal, wheat middlings, soy flour as top ingredients
- • No artificial preservatives — BHA, BHT, and ethoxyquin are linked to health concerns
- • No artificial colors — Red 40, Yellow 5, Blue 2 serve no nutritional purpose for dogs
- • Omega fatty acids — Flaxseed, fish oil, or salmon oil support skin and coat health
- • Joint support for seniors — Glucosamine and chondroitin for older dogs
