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 Collie weighs males 60–75 lb, females 50–65 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 Collie weight.

Good to know
The AKC sums up the Collie in three words: graceful, proud, devoted. How active yours really is matters more for the bowl than the breed name, so pick the column that fits your own dog.
