The WSAVA five-question framework

WSAVA's Global Nutrition Committee publishes a one-page checklist for evaluating any pet food manufacturer. The answers should be available without a phone call.

  1. Does the manufacturer employ a full-time qualified nutritionist (PhD or board-certified DACVN/ECVCN)?
  2. Who formulates the diets, and what are their qualifications?
  3. Where are the diets manufactured, and are quality-control measures published?
  4. What specific quality control measures are used (ingredient testing, finished-product testing)?
  5. Will the company provide a complete nutrient analysis, on request, of the specific product you're feeding?

A brand that won't or can't answer all five doesn't clear the bar, regardless of marketing.

What the label actually tells you

  • AAFCO statement, confirms the food is complete and balanced for a defined life stage. Prefer 'feeding trials' over 'formulated to meet' when both exist.
  • Guaranteed analysis, minimum protein and fat, maximum fiber and moisture. Useful for comparing within a category, not across (wet vs dry).
  • Ingredient list, sorted by weight pre-cooking, so it overstates fresh meat. Don't read too much into the top three names.
  • Calorie content (kcal/cup or kcal/can), required by AAFCO and the only number you need to calculate portions.

What to ignore

  • Buzzwords without regulatory meaning: 'human-grade', 'holistic', 'super-premium', 'ancestral'.
  • Ingredient-splitting tricks that push meat up the list by breaking grains into three sub-types.
  • Front-of-bag claims that an ingredient is 'first', re-read after rehydration, the math shifts.
