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 Rottweiler weighs 80–135 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 Rottweiler 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 24-27 in, bitches 22-25 in); weight from AKC Breed Weight Chart.
Good to know
The AKC sums up the Rottweiler in three words: confident guardian, loyal, loving. How active yours really is matters more for the bowl than the breed name, so pick the column that fits your own dog.
Rottweiler puppies are large-breed puppies. VCA Animal Hospitals advises steady, measured feeding of a large-breed puppy food rather than free feeding, and notes that big breeds can take 18 to 24 months to reach adulthood. Use the puppy calculator until then.
