How much should I feed my dog? (by weight, with a chart)

Feeding is really a question of energy. A dog needs a certain number of calories a day — its maintenance energy requirement, or MER (the daily energy an average adult dog needs to hold a steady, healthy weight) — and that number scales with body weight. Bigger dog, more calories. The amount of food on the plate is just whatever delivers that energy.
A starting-point chart by weight
The table below gives a rough daily energy range for a typical adult dog at each weight, based on standard veterinary energy estimates. Treat it as an orientation, not a prescription — an active young dog sits at the top of the range, a calm neutered senior near the bottom.
| Adult body weight | Approx. daily energy (starting point) |
|---|---|
| 5 kg | ~320–430 kcal/day |
| 10 kg | ~530–730 kcal/day |
| 20 kg | ~900–1230 kcal/day |
| 30 kg | ~1200–1670 kcal/day |
| 40 kg | ~1500–2070 kcal/day |
Why homemade portions look different from kibble
One thing that trips people up: you cannot copy a kibble feeding chart onto a fresh bowl. Kibble is dry and calorie-dense, so a small scoop carries a lot of energy. Fresh food is mostly water, so the same number of calories is a visibly larger, heavier bowl. The dog is getting the same energy either way — the fresh portion just looks bigger because you have not paid to remove the water. Judge by calories and body condition, not by how the pile compares to a cup of kibble.
Sizing it to the gram
A chart gets you in the right neighbourhood; the exact grams depend on which meats you use and their fat content. Growlrr’s recipe-builder takes your dog’s weight, life stage and activity and sizes the daily bowl precisely, then tells you the single 5 g Growlrr BowlBalancer™ sachet dose that completes it to the NRC 2006 nutrient floors. No cup-counting guesswork — a complete fresh bowl, measured for your dog.
