How much to feed a Greater Swiss Mountain Dog
A neutered adult Greater Swiss Mountain Dog at 140 lb needs about 2519 kcal a day, which is 6¾ cups of a 369 kcal/cup food; at the 90 lb end of the breed's range it is 1809 kcal, or 5 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.

Greater Swiss Mountain Dog feeding table by weight and life stage
Each row is a Greater Swiss 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.

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 140 lb Greater Swiss Mountain Dog the gap between the intact and neutered columns is 315 kcal a day, roughly 0.9 cups. A dog that is already carrying extra weight should start from the inactive column (2205 kcal at 140 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 140 lb and 2519 kcal, 6¾ cups is about 648 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 Greater Swiss Mountain Dog puppy feeding chart.
How the Greater Swiss 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 140 lb Greater Swiss Mountain Dog needs 18 kcal per pound; a 130 lb Akita (American) needs 2383 kcal (18 per lb), a 130 lb Bullmastiff needs 2383 kcal (18 per lb), a 130 lb Black Russian Terrier needs 2383 kcal (18 per lb). The breed ranks 120 of 132 by weight on this site. Females of the breed top out around 110 lb, which is 2103 kcal a day neutered.
