A 150 lb (68.0 kg) dog has a resting energy requirement of 1658 kcal. As a neutered adult with normal activity that becomes 2653 kcal a day, or 7¼ cups of a 369 kcal/cup kibble; an intact adult needs 2985 kcal, and a dog that is inactive or gains weight easily 2322 kcal. Puppies that currently weigh 150 lb need far more: 4975 kcal under four months, 3317 kcal after.

Reading the table
Pick the row that describes the dog, then the column that matches the kcal per cup on your bag — it is printed near the guaranteed analysis, usually as "kcal/cup" or "kcal ME/cup". The puppy rows apply to a puppy that weighs 150 lb today; a growing puppy should be re-weighed and the amount recalculated every two weeks, which the breed puppy charts do for you. At this size the gap between the neutered and intact rows is 332 kcal — about 0.9 cups a day — so the right row matters more than the brand of food.
These are maintenance starting points for a healthy dog. Weigh the dog monthly and check body condition — ribs easy to feel, visible waist — and adjust by about 10% if it is drifting. Pregnant or nursing dogs, working dogs and dogs with a diagnosed condition need a vet's number, not a table.
Other sizes for a 150 lb dog
A 150 lb dog is above the manufacturer's largest crate band (110 lb), so look at 54 in crates and measure, and a X-Large rectangle bed (53 × 35 in) on Orvis's chart. Harness size depends on chest girth rather than weight — see the harness size chart.
