Feeding a Senior Small-breed dog
Small breeds typically weigh 13β25 lb. Using a 18 lb example as a midpoint, a senior dog at that weight needs roughly 440 calories a day, which is about 1.16 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.
