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 Cocker Spaniel weighs 20–30 lb (AKC Breed Weight Chart (combined male/female range; AKC standard gives no weight)). 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 Cocker Spaniel weight.

Daily totals with no treats. Worked out from resting energy (70 × kg0.75) and the AAHA 2021 life-stage factors. Weight source note: AKC standard gives height only (dogs 15 in, bitches 14 in ideal); weight from AKC Breed Weight Chart.
Good to know
The AKC sums up the Cocker Spaniel in three words: gentle, smart, happy. How active yours really is matters more for the bowl than the breed name, so pick the column that fits your own dog.
