Dog Food Portion Calculator

Convert your dog's daily calorie target into measured cups and grams per meal by reading the kcal per cup or 100g from the food label

Frequently Asked Questions

How is the daily food portion calculated?

First the dog's daily calories are estimated: RER = 70 × (body weight in kg)^0.75, multiplied by a life-stage factor (neutered adult ≈ 1.6, intact ≈ 1.8, puppy 2–3, weight loss ≈ 1.0). Then calories are divided by the food's caloric density (kcal per cup or per gram, printed on the bag) to give cups and grams. This is general guidance, not veterinary advice - consult your veterinarian for personalized recommendations for your pet.

Why do I need the kcal/cup from my specific bag?

Pet foods range from roughly 300 to 500+ kcal per cup. Two foods at the same weight can differ 50% in calories, so a generic "cups per day" chart is unreliable. Always use the density on your bag for an accurate portion. This is general guidance, not veterinary advice - consult your veterinarian for personalized recommendations for your pet.

How does this differ from a dog calorie calculator?

A calorie calculator stops at kcal per day. This tool converts that energy target into a real, measurable portion (cups and grams), splits it across meals, and reserves room for treats.

How much of the diet can be treats?

Keep treats to no more than 10% of daily calories so the complete-and-balanced diet still meets nutrient needs. The calculator subtracts a treat allowance from the meal portions. This is general guidance, not veterinary advice - consult your veterinarian for personalized recommendations for your pet.
