Why does the cup count change so much between foods?

Because a cup measures volume, not calories. Two foods can both fill the same cup and differ by more than a third in calories, so the same dog needs a different number of cups from each. That is why a cup figure without a calorie figure cannot be checked.

Should I use cups or grams?

Grams are more accurate for a dog. Cups of kibble vary with the shape of the pieces and how the cup is filled, while grams are grams. Use the calculator above for the cup estimate, then weigh the food on a kitchen scale if you can.

What about a puppy, a senior dog, or an overweight dog?

This page and calculator use the adult, neutered, typical-activity figure (1.6 times resting energy). Puppies, senior dogs and dogs on a weight-loss plan need different multipliers, so use the pages for those life stages instead of scaling the cups here.

How many cups of food should I feed my dog?

Q: How many cups of food should I feed my dog?

It depends on your food's calories per cup. On a 370 kcal/cup food, a 10 kg neutered adult dog of typical activity eats about 1.7 cups a day (about 630 kcal / 370), roughly 187 g. The same dog on a lighter 350 kcal/cup food needs about 1.8 cups, and on a denser 400 kcal/cup food about 1.6 cups. Cups are an estimate at 110 g per cup.

It depends on your food's calories per cup, not only your dog's weight. On a 370 kcal/cup food, a 10 kg neutered adult dog of typical activity eats about 1.7 cups a day — about 630 kcal ÷ 370 — which is roughly 187 g. The same dog on a lighter 350 kcal/cup food needs about 1.8 cups, and on a denser 400 kcal/cup food only about 1.6 cups. That spread is why a cup figure without a calorie figure is not an answer.

A cup measures volume; what your dog needs is energy. Two foods can look identical in the scoop and differ by more than a third in calories — so the number of cups changes with the bag, not just with the dog. This page gives you the chart, a calculator for your own food, and the one number that makes either of them checkable.

Work out the cups for your own dog

The chart, by weight

Which column applies to you depends on your bag, not on your dog. Find the weight, then read across to your food's calorie figure:

Dog's weight	Daily calories	350 kcal/cup	370 kcal/cup	400 kcal/cup
5 kg	374	1.07 cups	1.01 cups	0.94 cups
10 kg	630	1.80 cups	1.70 cups	1.57 cups
15 kg	854	2.44 cups	2.31 cups	2.13 cups
20 kg	1,059	3.03 cups	2.86 cups	2.65 cups
30 kg	1,436	4.10 cups	3.88 cups	3.59 cups

Adult, neutered, typical activity (1.6× resting energy). Cup figures assume 110 g per cup — use your own bag's grams-per-cup figure if it states one. Every figure is produced by the same engine that runs the calculator above.

Why the cup count moves with the food, not just the dog

A cup is a volume, and kibble is mostly air. Two foods can fill the same cup and differ by more than a third in calories, which means the same dog needs a very different number of cups from each. A 350 kcal/cup food is a lighter formula; a 400 kcal/cup one is dense. That 14% difference in energy density moves the 10 kg dog from 1.8 cups to 1.6 — and it is invisible in the scoop.

The practical consequence is the one this page keeps repeating: the calories on your bag are the number that matters, and the cups follow from it. If you switch foods without re-reading the calorie figure, the amount in the bowl changes even though the scoop did not. That is the single most common way dogs gain weight on "the same amount".

Where these numbers come from

Every figure above is produced by the same calculation engine that runs the calculators on this site, in three steps:

Resting energy requirement: RER = 70 × kg^0.75 — the NRC energy equation.
Life-stage factor: × 1.6 for a neutered adult of typical activity.
Divide by the food: daily calories ÷ kcal per cup = cups per day.

The same factor tables, with their sources, are published in the open reference dataset (CC BY 4.0) — so any number on this page can be re-computed independently. Our full method is described on how we check our numbers.

Weigh the food, do not scoop it

Cups are the convenient measurement, not the accurate one. Kibble shape and how you fill the cup both change what a "cup" weighs, and for a dog eating 1.7 cups a day a 15% error is a meaningful share of the day's calories. A kitchen scale removes the guesswork — the page on measuring dog food without a scale covers the alternatives if you would rather not, and how many cups are in a pound works the volume-to-weight conversion the other way.

Common follow-up questions

Is this the same as the chart on the bag? No. Bag charts are written for a broad group and usually rounded upward, and they often assume a single food density. This one is calculated from your dog's weight and your food's calories — see why the bag chart overfeeds.

What if I feed wet food as well? Wet food is mostly water, so it cannot be swapped cup for cup. Convert it on calories — the wet to dry conversion page does the arithmetic.

How many meals a day? Most adult dogs do well on two measured meals. The feeding chart by weight covers meal patterns and the adjustment for a dog that is not a neutered adult of typical activity.

Measuring by weight instead? Browse measuring cups and scoops on Amazon — a scale is more accurate, but a marked scoop beats an unmarked one.
