Feeding by breed and weight / Working group
How much to feed a Rottweiler
A neutered adult Rottweiler at 132 lb needs about 2411 kcal a day, which is 6½ cups of a 369 kcal/cup food; at the 110 lb end of the breed's range it is 2103 kcal, or 5¾ cups. That is the maintenance figure before treats, from the resting energy requirement formula and the Merck Veterinary Manual's factor of 1.6 for a neutered adult.
Rottweiler feeding table by weight and life stage
Each row is a Rottweiler at that weight. Columns are the Merck factors: a neutered adult (×1.6), an intact adult (×1.8) and a dog that is inactive or gains weight easily (×1.4). Cups assume 369 kcal per cup, the label figure for Purina Pro Plan Complete Essentials Shredded Blend Chicken & Rice (adult dry); change it to your bag's number on the sizer.
| Weight | RER | Neutered adult | Cups | Intact adult | Cups | Inactive / weight-prone | Cups |
|---|---|---|---|---|---|---|---|
| 110 lb (49.9 kg) | 1314 | 2103 kcal | 5¾ | 2365 kcal | 6½ | 1840 kcal | 5 |
| 116 lb (52.6 kg) | 1368 | 2188 kcal | 6 | 2462 kcal | 6¾ | 1915 kcal | 5¼ |
| 121 lb (54.9 kg) | 1412 | 2258 kcal | 6 | 2541 kcal | 7 | 1976 kcal | 5¼ |
| 127 lb (57.6 kg) | 1464 | 2342 kcal | 6¼ | 2635 kcal | 7¼ | 2049 kcal | 5½ |
| 132 lb (59.9 kg) | 1507 | 2411 kcal | 6½ | 2712 kcal | 7¼ | 2109 kcal | 5¾ |

Why the number is lower than the bag says
Bag feeding guides are written for an active, intact adult and often run above the neutered-maintenance figure; for a 132 lb Rottweiler the gap between the intact and neutered columns is 301 kcal a day, roughly 0.8 cups. A dog that is already carrying extra weight should start from the inactive column (2109 kcal at 132 lb) and be weighed every two weeks. Treats and chews count: a single dental chew can be 70–100 kcal, which adds up faster than it looks across a week.
Formulas get a healthy adult into the right range; body condition keeps it there. Ribs should be easy to feel under a thin layer of fat, and the dog should have a visible waist from above. If that is not the case after four weeks, adjust by about 10% and re-check — and ask your vet before changing a dog with a medical condition, a pregnant or nursing female, or a working dog in season.
Grams and meals
At 132 lb and 2411 kcal, 6½ cups is about 624 g a day of a 96 g/cup kibble — a kitchen scale is more repeatable than a scoop. Split into two meals for an adult; for a deep-chested breed of this size, two or three smaller meals rather than one large one is the usual advice to reduce bloat risk, and your vet can say whether it applies to your dog. Puppies eat more per pound and more often: see the Rottweiler puppy feeding chart.
How the Rottweiler compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 132 lb Rottweiler needs 18 kcal per pound; a 130 lb Akita (American) needs 2383 kcal (18 per lb), a 110 lb Cane Corso needs 2103 kcal (19 per lb), a 120 lb Bernese Mountain Dog needs 2244 kcal (19 per lb). The breed ranks 44 of 49 by weight on this site. Females of the breed top out around 106 lb, which is 2045 kcal a day neutered.
