The answer, in one line
A breed does not have a calorie requirement — a body does. What a breed gives you is a defensible weight to put into the standard formula when you have no scale reading, and a sanity check on the number you got from somewhere else. Put the breed's typical adult weight into RER = 70 × kg0.75 and multiply by 1.6 for a neutered adult, and the whole breed spread collapses into one line: a Chihuahua needs roughly 240 kcal a day, a Beagle 540–790, a Labrador 1,250–1,660, a Rottweiler 1,660–2,450, a Great Dane 2,100–2,980.
Why no reference calculator starts from breed
The calorie calculators published by the veterinary nutrition alliance, the veterinary calculator sites and the pet obesity charity all open with the same thing: a weight field, an optional body-condition score, a neuter toggle, sometimes a food-label field. Breed appears nowhere, because the formula does not need it — resting energy requirement is a function of mass, and mass is the number a clinic already has on the chart.
That is fine in a consulting room and unhelpful in a kitchen. The person typing into a browser at 11pm usually knows "he's a Lab" and not "he's 32.4 kg". One of the three reference suites does publish breed weight ranges as a separate look-up — but it stops at weight, compares your dog against the range and never converts the range into calories. The gap between "your Lab is within the typical range" and "your Lab needs about 1,450 kcal a day" is where this page lives, and nothing on those three sites fills it.
Breed sets the weight, not the metabolism
This is the part that trips people up, and it is arithmetic rather than opinion. Energy requirement scales with body weight raised to the power 0.75, not with body weight itself. So a dog that is eleven times heavier is not eleven times hungrier — it is roughly six times hungrier. Calories per kilogram fall steadily across the size range, from about 87 kcal per kg at Chihuahua weights to about 40 at Great Dane weights.
Daily calories for 18 breeds
Neutered adult, typical activity, 1.6 × RER. The spread inside a single row is the honest part of this table: a Labrador can be 55 lb or 80 lb, and that is a 400 kcal-a-day difference between two dogs of the same breed.

*Cups per day assumes a typical adult kibble at 350 kcal per cup, measured by weight at 110 g per cup. Your bag is the real number: a 450 kcal/cup food turns a Labrador’s 1,250 kcal into about 2.8 cups instead of 3.6. Divide your kcal target by your own kcal per cup and the cups column follows.
Where a breed standard states a ceiling rather than a range — Chihuahuas "not exceeding 6 pounds", French Bulldogs "under 28 pounds" — the table uses the ceiling. Rows sourced from Wikipedia carry that link; every other row links to the AKC breed page the weight came from.
Where breed genuinely moves the number
Weight explains most of it, but not all of it. Three breed-level effects are real enough to change what you do with the figure:
Appetite is partly inherited
A 2016 study in Cell Metabolism found that Labrador Retrievers carrying a deletion in the POMC gene were heavier and more food-motivated than Labs without it — the first time a specific gene variant was tied to weight and appetite in a named breed. It does not change the calorie arithmetic by a single kcal. What it changes is the owner: a dog that is wired to beg will beg at 1,400 kcal and at 1,700, and the begging is not evidence of hunger. Labs are also the breed most often flagged as obesity-prone in general feeding guidance, which is a good argument for starting at the bottom of the breed range rather than the middle.
Some breeds have an exercise ceiling
Flat-faced breeds — French Bulldogs, Bulldogs, Pugs — are described by the AKC as prone to breathing difficulty and poorly tolerant of heat and exertion. A dog that cannot be run hard cannot be fed as if it is being run hard. For those breeds the 1.4 × RER "obesity prone" factor is usually the honest default rather than a special case, and the breed's own club material warns about weight gain explicitly.
Giants are a different feeding problem
A 140 lb Great Dane eating 2,500 kcal a day is eating roughly ten Chihuahua portions, and the breed's own guidance points at bloat as the leading cause of death — with several small meals a day and no vigorous exercise around mealtimes as the standard precaution. That is a meal-frequency problem, not a calorie problem, and it is the one place where a breed-by-breed page should send you to a vet rather than to a formula.
The fourth effect is the one nobody can tabulate: two dogs of the same breed, same weight and same household can differ by 20–30% in what they actually burn. Working lines, show lines, thyroid status and plain individual variation all live in that gap, which is why the reference table itself is published with a footnote saying any calculated intake is only a starting point to be modified on response.
How to use the number
Start at the low-to-middle of the breed range, feed it unchanged for two weeks, then look at the dog rather than the bowl: ribs you can feel but not see, a waist from above, a tuck behind the last rib. Adjust by about 10% and repeat. If you already know the dog's weight, skip the breed entirely and put that weight into the dog calorie calculator — a real number beats a breed average every time. For meal timing, the treat allowance and the two-week adjustment rule in full, see how many calories should I feed my dog. To turn the daily figure into cups and grams of your own food, use the dog food calorie calculator.
Where this estimate breaks down
Mixed breeds have no standard weight, so the breed route is closed — weigh the dog, or use the parent breeds as a bracket and expect it to be wide. Dogs at the edge of their breed's range, show-line versus field-line Labradors, and any dog with a body condition score above 5 out of 9 should be fed on their own weight and condition, not on the breed average. Puppies are a separate calculation entirely — a growing puppy eats two to three times its resting requirement, and the numbers on this page are adult maintenance figures; use the puppy calorie calculator instead. Pregnant, nursing, ill or clinically managed dogs are outside every formula here. And if the dog is already overweight, the number you want is a target, not a maintenance figure — that is what the dog weight loss calculator is for.
Frequently asked questions
How many calories does a Labrador need a day?
Around 1,250 to 1,660 kcal for a neutered adult, because the AKC weight range for the breed runs from 55 lb to 80 lb. A typical 65–80 lb male lands near 1,420–1,660; a 55–70 lb female near 1,250–1,500. Labs are also one of the breeds most often flagged as obesity-prone, so start at the bottom and adjust on condition rather than on appetite.
Why does a big dog need fewer calories per pound than a small one?
Because energy requirement scales with body weight to the power 0.75, not with body weight. Doubling a dog's weight multiplies its resting requirement by about 1.68, not 2. That is why the per-kilogram figure slides from roughly 87 kcal at Chihuahua weights to roughly 40 at Great Dane weights — and why "feed 2% of body weight" quietly over-feeds big dogs and under-feeds small ones.
Is a breed-based number accurate enough to feed by?
It is accurate enough to start, and not accurate enough to stop. A breed range can be 40% wide from bottom to top, so the figure is a bracket to test against body condition over a fortnight. Weigh the dog once and the bracket disappears; that single measurement is worth more than any breed table.
How many calories does a Great Dane eat compared with a Chihuahua?
About 2,100 to 2,980 kcal a day for a 110–175 lb Dane against roughly 240 kcal for a 6 lb Chihuahua — twelve times the calories for roughly twenty-five times the weight. Per kilogram it is the other way round: the Dane runs near 40 kcal per kg, the Chihuahua near 87.
