Dog Food Calculator by Breed
Short answer
The right amount to feed depends on your dog’s weight and life stage, not its breed name — a Labrador and a Greyhound of the same weight need similar calories. Enter your dog’s actual weight below; use its breed only to know its healthy adult weight range.
Calories per cup is on your food’s bag (usually 300–500 kcal/cup). Adjust it for an accurate cups-per-day figure.
Your dog needs about 794 calories a day, roughly 2.3 cups.

Based on 350 kcal per cup — check your food’s label and adjust above.
Estimate only, from the RER = 70 × kg^0.75 formula with a life-stage factor. Confirm the right amount with your veterinarian and adjust to your dog’s body condition.
Consult your vet
These figures are planning estimates from the standard RER/MER formula and are not a substitute for veterinary advice. Your dog’s real needs depend on breed, body condition, health, and the specific food. Confirm the right amount with your veterinarian and adjust based on your dog’s body condition over time.

Frequently asked questions
Does breed change how much I feed my dog?
Not directly — calories are driven by body weight and life stage. Breed matters because it sets a dog’s healthy adult weight and its typical activity level. Feed to your dog’s ideal weight and adjust for its activity.
How much should I feed a large-breed dog?
Use the same RER × factor formula with your dog’s weight. Large and giant breeds reach their adult amount later (up to 18–24 months) and large-breed puppies need controlled growth — ask your vet about large-breed puppy food.
