Dog food calculator

How much to feed each day, based on weight, life stage, and the calories in your dog's food.

On the label as "metabolizable energy" or "kcal/kg".

US labels usually list "kcal/cup".

Enter your dog's weight to see the result.

How it's calculated

First, resting energy is calculated with the standard veterinary formula: 70 × body weight in kg raised to the 0.75 power. Then it's multiplied by a life-stage factor: 1.6 for a spayed or neutered adult, 1.8 for an intact adult, 1.2 to 1.4 for an inactive dog, and 2 to 3 for puppies.

It's a starting point, not a prescription. Every dog burns energy differently: weigh yours monthly, feel for the ribs (you should find them without pressing), and adjust by about 10% either way. Treats count toward the total.

Frequently asked questions

How much should I feed my dog per day?

It depends on weight, life stage, and the food's calories. For example, a 11 lb spayed or neutered adult needs about 370 kcal a day; with a food of 370 kcal per cup, that's about one cup.

Where do I find my dog food's calories?

On the bag or the maker's website, listed as metabolizable energy in kcal per kg or kcal per cup.

Does this work for dogs with health problems?

No. If your dog has a medical condition, is very overweight, or eats a prescription diet, your vet should set the amount.
