How Much Protein Does a Dog Need?
Protein is the most critical macronutrient in a dog’s diet, providing essential amino acids for muscle maintenance, immune function, coat health, and enzyme production. The AAFCO minimum for adult dogs is 18% DM (dry matter basis), but optimal intake is significantly higher — especially for active dogs and puppies.
Protein Requirements by Life Stage
| Life Stage | g protein/kg BW | AAFCO DM % |
|---|---|---|
| Adult (sedentary) | 2.0-2.5 g/kg | 18% minimum |
| Active adult | 3.0-4.0 g/kg | 25-30% |
| Puppy | 5.0-6.0 g/kg | 22.5% minimum |
| Senior | 2.0-3.0 g/kg | 18-25% |
FAQs
Can a dog have too much protein?
In healthy dogs, excess protein is simply excreted via urine — it does not cause kidney damage in dogs with normal kidney function. Dogs with pre-existing kidney disease should follow vet-prescribed protein restrictions. High-protein diets can contribute to weight gain if total calories exceed needs.
What are the best protein sources for dogs?
Chicken, beef, turkey, lamb, salmon, and eggs are all excellent high-biological-value protein sources. Plant proteins (legumes, grains) are lower in biological value but can complement animal proteins in balanced commercial diets.
