How much to feed a Borzoi
A neutered adult Borzoi at 105 lb needs about 2031 kcal a day, which is 5½ cups of a 369 kcal/cup food; at the 75 lb end of the breed's range it is 1578 kcal, or 4¼ 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.

Borzoi feeding table by weight and life stage
Each row is a Borzoi 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 105 lb Borzoi the gap between the intact and neutered columns is 253 kcal a day, roughly 0.7 cups. A dog that is already carrying extra weight should start from the inactive column (1777 kcal at 105 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 105 lb and 2031 kcal, 5½ cups is about 528 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 Borzoi puppy feeding chart.
How the Borzoi compares
Calories per pound fall as dogs get bigger, because RER scales with weight to the 0.75 power rather than linearly. A 105 lb Borzoi needs 19 kcal per pound; a 105 lb Giant Schnauzer needs 2031 kcal (19 per lb), a 101 lb Old English Sheepdog needs 1972 kcal (20 per lb), a 100 lb Doberman Pinscher needs 1958 kcal (20 per lb). The breed ranks 112 of 132 by weight on this site.
