Feeding a Puppy Giant-breed dog
Giant breeds typically weigh over 90 lb. Using a 120 lb example as a midpoint, a puppy dog at that weight needs roughly 2806 calories a day, which is about 7.38 cups of a typical 380 kcal/cup food, split across two meals. Puppies need far more energy per pound than adults because they're growing, so this factor is high; taper it down as they approach adult size. Always calibrate to your dog's body condition and use the exact calories-per-cup on your bag.
