Also a part of the AKC’s official "Most Active Dog Breeds" list, the Dalmatian is an activity-loving, high-energy hound. One of its early occupations was to run ahead of horse-drawn firefighting carriages to clear a path and lead the horses to the fire. Keeping pace with an animal more than twice your size sounds like no easy feat, so clearly the Dalmatian is one pretty fit puppy.
