Dog Protein Calculator
Calculate how much protein your dog needs daily and whether their current food is meeting that target.
What Is the Dog Protein Calculator?
Calculate how much protein your dog needs daily and whether their current food is meeting that target.
Protein is the most critical macronutrient in a dog's diet. It supports muscle maintenance, immune function, skin and coat health, and virtually every body process. This calculator shows your dog's daily protein requirement in grams.
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
Dogs require protein expressed as grams per kilogram of bodyweight. The National Research Council (NRC) recommends a minimum of 4g of digestible protein per kilogram of bodyweight per day for adult dogs. Puppies and active dogs need more — 6g/kg/day is a reasonable target.
This calculator multiplies your food's protein percentage by the daily gram amount to get actual protein delivered, then compares it to the minimum requirement for your dog's weight and life stage.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
