Feeding by breed and weight / Working group
How much to feed a Bernese Mountain Dog
A neutered adult Bernese Mountain Dog at 120 lb needs about 2244 kcal a day, which is 6 cups of a 369 kcal/cup food; at the 80 lb end of the breed's range it is 1656 kcal, or 4½ 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.
Bernese Mountain Dog feeding table by weight and life stage
Each row is a Bernese Mountain Dog 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 |
|---|---|---|---|---|---|---|---|
| 80 lb (36.3 kg) | 1035 | 1656 kcal | 4½ | 1863 kcal | 5 | 1449 kcal | 4 |
| 90 lb (40.8 kg) | 1131 | 1809 kcal | 5 | 2035 kcal | 5½ | 1583 kcal | 4¼ |
| 100 lb (45.4 kg) | 1223 | 1958 kcal | 5¼ | 2202 kcal | 6 | 1713 kcal | 4¾ |

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 120 lb Bernese Mountain Dog the gap between the intact and neutered columns is 281 kcal a day, roughly 0.8 cups. A dog that is already carrying extra weight should start from the inactive column (1964 kcal at 120 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 120 lb and 2244 kcal, 6 cups is about 576 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 Bernese Mountain Dog puppy feeding chart.
How the Bernese Mountain Dog compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 120 lb Bernese Mountain Dog needs 19 kcal per pound; a 100 lb Doberman Pinscher needs 1958 kcal (20 per lb), a 110 lb Cane Corso needs 2103 kcal (19 per lb), a 130 lb Akita (American) needs 2383 kcal (18 per lb). The breed ranks 41 of 49 by weight on this site. Females of the breed top out around 100 lb, which is 1958 kcal a day neutered.
