Portions scale with body weight using the veterinary RER formula. These are starting points for a typical active adult dog; split into two meals.
| Dog weight | Daily calories | Dry food (approx) |
|---|---|---|
| 5 kg (11 lb) | ~375 cal | ~110 g (1 cup) |
| 10 kg (22 lb) | ~630 cal | ~180 g (1.5 cups) |
| 20 kg (44 lb) | ~1060 cal | ~300 g (2.5 cups) |
| 30 kg (66 lb) | ~1435 cal | ~410 g (3.5 cups) |
| 40 kg (88 lb) | ~1780 cal | ~510 g (4.25 cups) |
Dry food assumes ~3.5 cal/g; check your brand. Puppies need more, seniors and neutered dogs less.
Overfeeding is the #1 cause of pet obesity, affecting over 50% of dogs. Using a scale to weigh food portions (instead of eyeballing) and calculating the right amount based on your dog's specific weight prevents this. Our calculator uses the same RER formula veterinarians use in clinical practice.
