Dog feeding by weight
Last updated: November 3, 2026
A quick reference of estimated daily calories for common adult dog weights. The low end assumes a less active or weight-loss-prone dog (×1.2 RER); the high end assumes an active dog (×2 RER). Most typical adults fall somewhere in between.
| Body weight | Estimated daily calories |
|---|---|
| 10 lb (4.5 kg) | 261–435 kcal/day |
| 20 lb (9.1 kg) | 439–732 kcal/day |
| 50 lb (22.7 kg) | 873–1,455 kcal/day |
| 80 lb (36.3 kg) | 1,242–2,070 kcal/day |
These are estimates only. Individual needs can vary by 20–30% or more, and this table does not cover puppies, kittens, seniors, or pets with medical conditions. It is educational information, not veterinary advice.
