Feeding a Senior Large-breed dog
Large breeds typically weigh 51β90 lb. Using a 70 lb example as a midpoint, a senior dog at that weight needs roughly 1217 calories a day, which is about 3.2 cups of a typical 380 kcal/cup food, split across two meals. Seniors are usually less active, so the factor is lower than for a working adult, so watch body condition and adjust. Always calibrate to your dog's body condition and use the exact calories-per-cup on your bag.
