Feeding a Senior Medium-breed dog
Medium breeds typically weigh 26β50 lb. Using a 38 lb example as a midpoint, a senior dog at that weight needs roughly 770 calories a day, which is about 2.03 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.
