This video opens up the possibility for the ultimate dog sport, surpassing sheep trials, agility, obedience, herding, tracking, flyball, frisbee, you-name-it.
Sheep agility. Wherein a human trainer instructs a Border Collie to guide sheep through an agility course. It combines the best of both worlds, it has herding instinct, athletic prowess, independent thinking on the part of the dog, unpredictability on the part of the sheep, can be played in the city and suburbs with ease, can be done indoors and outdoors, and makes for a great spectator sport.
Mark my words, within three years, the versatility breeders will be pushing to AKC to adopt a championship and competition schedule for agilitrialing. It will need to get a better name, but this sport has massive potential!
