The Border Collies are commonly used in the agility competitions, as sports like agility are right the this intelligent dogs alley. The Border Collie is highly energetic with great stamina. Provided it gets sufficient activity to keep it occupied and ample exercise, the Border Collie will get along quite happily with other dogs, and children, however the Border Collie may be aggressive with other dogs of the same sex.
