What Is the Dog Nutrition Calculator?

Check if your dog's food meets AAFCO minimum nutritional standards for their life stage.

Not all dog foods meet the minimum nutritional standards set by AAFCO (Association of American Feed Control Officials). This tool checks your food's protein content against the appropriate minimums for your dog's life stage.

Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works

AAFCO sets minimum nutrient profiles for dog foods — the floor below which a diet is considered nutritionally inadequate. For adult dogs, the minimum protein is 18% on a dry matter (DM) basis. For puppies and pregnant/lactating dogs, it's 22%.

This calculator checks your food's protein percentage against these minimums and tells you whether the food meets requirements. A food that barely meets minimums is not necessarily optimal — most nutritionists recommend 25-30% protein for adult dogs.

Frequently Asked Questions

What does AAFCO minimum mean?+
AAFCO sets the minimum nutrient levels a dog food must contain to be nutritionally complete. Meeting the minimum is the baseline — it does not mean the food is optimal.
What is a good protein percentage for dog food?+
Adult dogs: 22-32% is considered a healthy range. Puppies: 25-30%. Senior dogs with healthy kidneys: 25-28%. Active or working dogs may benefit from higher protein.
Does dry matter percentage matter?+
Yes. Always compare proteins on a dry matter basis, not as-fed, especially when comparing wet and dry foods. Wet food appears lower protein because of water content.
My food says 26% protein — is that enough?+
For most adult dogs, yes. It exceeds the AAFCO minimum of 18%. Whether it is optimal depends on your dog's individual needs, activity level, and health status.
Should I consult a vet about nutrition?+
For healthy dogs on commercial complete food, a standard annual vet check is sufficient. For dogs on homemade diets, or with health conditions, consult a board-certified veterinary nutritionist.
