Feeding a Adult Giant-breed dog
Giant breeds typically weigh over 90 lb. Using a 120 lb example as a midpoint, a adult dog at that weight needs roughly 2244 calories a day, which is about 5.91 cups of a typical 380 kcal/cup food, split across two meals. This is a maintenance estimate for a typical neutered adult; active or working dogs need more. Always calibrate to your dog's body condition and use the exact calories-per-cup on your bag.
