For hobbits, the schedule is typically breakfast, second breakfast, elevenses, luncheon, afternoon tea, dinner, and finally supper. Dogs, according to Jimmy Craig’s They Can Talk, also dine at second dinner, which is between dinner and supper. The dog in this webcomic--who will bring up the topic later--also desires tiffin, brunch, lupper, high tea, siu yeh, and the midnight snack.
The dog who engages in vigorous athletic activities, such as guarding the den from the mailman, may require additional calories and engage in snacking as needed to keep up his strength.
