Quick answer: An average adult Rottweiler (108 lb / 49 kg) needs about 2067 kcal a day if spayed or neutered — roughly 5.4 cups of a typical dry food, split into two meals. Rottweiler puppies need more per pound: about 2.5 cups a day at 2 months, rising to 6.3 cups by 12 months.
A starting point, not a prescription. Weigh your dog every 2-4 weeks and adjust by about 10% if they gain or lose weight you didn't intend. Treats should stay under 10% of daily calories.

How much should I feed my Rottweiler?
An average adult Rottweiler (108 lb / 49 kg) needs about 2067 kcal a day if spayed or neutered — roughly 5.4 cups of a typical dry food, split into two meals. Rottweiler puppies need more per pound: about 2.5 cups a day at 2 months, rising to 6.3 cups by 12 months.
How much should I feed a Rottweiler puppy?
It depends on age and current weight. Using a typical growth curve, a Rottweiler puppy eats about 2.5 cups at 2 months, 3.8 cups at 3 months, 4.1 cups at 4 months, 4.4 cups at 5 months, 4.8 cups at 6 months, 5.8 cups at 9 months, 6.3 cups at 12 months. Weigh your puppy every couple of weeks and recalculate, because amounts rise quickly.
How many times a day should a Rottweiler eat?
Four meals a day until about 3 months, three until 6 months, then two meals a day for life. Two smaller meals rather than one large one is also often recommended for deep-chested large breeds because of bloat risk.
When should a Rottweiler switch to adult food?
As a large breed, Rottweilers typically reach adult weight by 12-18 months, with continued filling out past that. Most owners switch around the time a puppy reaches adult size, and large-breed puppies should stay on a large-breed puppy formula until then to keep growth steady. See our guide on when to switch puppy food to adult food.
