Dog Protein Calculator
Estimate your dog's daily energy needs and see an educational protein benchmark based on weight and life stage. Use it as a starting point—not as a veterinary prescription.
Calculate a Protein Benchmark
Enter your dog's details. The calculator estimates energy first, then applies a published protein-per-energy benchmark.
What does this dog protein calculator actually calculate?
This tool estimates a daily energy requirement using the standard RER equation 70 × body weight(kg)0.75 and an educational life-stage/activity factor. It then applies a protein-per-energy benchmark from AAFCO's dog nutrient profiles.
For adult-maintenance dog food, AAFCO's profile uses a minimum of 45 g crude protein per 1,000 kcal of metabolizable energy. For growth and reproduction, the minimum is 56.3 g per 1,000 kcal. These are nutrient-profile benchmarks for complete and balanced dog foods, not personalized prescriptions for an individual dog.
How to use the result
1. Start with the benchmark
Use the result to understand the approximate protein amount represented by the selected energy intake.
2. Check the food label
Pet-food labels normally list a minimum crude-protein percentage in the guaranteed analysis. Moisture matters when comparing protein percentages between foods.
3. Don't judge food by protein alone
A complete diet must provide many nutrients in appropriate amounts and ratios. A higher protein percentage does not automatically make a food better for every dog.
4. Consider life stage
Puppies and growing dogs have different nutrient requirements from adult-maintenance dogs. Pregnancy and nursing also require special consideration.

Frequently Asked Questions
How much protein does an adult dog need?
Protein needs vary with life stage, energy intake, diet and health. As a food-profile benchmark, AAFCO adult-maintenance dog food profiles use a minimum of 45 g crude protein per 1,000 kcal ME, or 18% on a dry-matter basis.
Do puppies need more protein?
Growing puppies have higher nutrient requirements than adult-maintenance dogs. AAFCO's growth and reproduction profile uses a minimum of 56.3 g crude protein per 1,000 kcal ME and 22.5% on a dry-matter basis.
Does a high-protein dog food mean it is healthier?
Not necessarily. Protein quantity is only one part of nutritional adequacy. The food also needs appropriate amounts and ratios of other essential nutrients for the dog's life stage and condition.
Can I use this calculator to formulate homemade dog food?
No. Protein is only one nutrient. A homemade diet requires appropriate amounts of many nutrients, and an unbalanced recipe can create nutritional problems. Use this tool for education and discuss homemade diets with a veterinary nutrition professional.
What does “crude protein” mean on a dog-food label?
Crude protein is a standardized analytical measure used in pet-food labeling. A guaranteed analysis normally lists a minimum crude-protein percentage along with other nutrient guarantees.
