The maths, with your numbers
No guesswork and no brand chart. This is the same calculation a vet does on paper, so you can check it.
A healthy adult Brittany weighs 30–40 lb (AKC official breed standard). Below are daily amounts for that range, for a typical dry dog food (382 kcal per cup, the middle of the dog foods in our list). For your own food, use the calculator above: it is already set to a Brittany weight.

|---|---|---|---|

Daily totals with no treats. Worked out from resting energy (70 × kg0.75) and the AAHA 2021 life-stage factors. Weight source note: Should weigh between 30 and 40 pounds.
Good to know
The AKC sums up the Brittany in three words: bright, fun loving, upbeat. How active yours really is matters more for the bowl than the breed name, so pick the column that fits your own dog.
