According to the American Kennel Club, Pembroke Welsh Corgis were ranked 15th most popular breed of dog in 2017. Pembroke Welsh Corgis can compete in dog agility trials, obedience, showmanship, flyball, tracking, and herding events. Herding instincts and trainability can be measured at noncompetitive herding tests. Corgis, despite their dwarfism giving the illusion of small slow legs, can reach up to 25 mph if they are healthy and fit. This is because Corgis tend to use more upper body strength to run than most dogs, giving them enhanced abilities with such activities as agililty and herding and racing.
