Border Collie
Exercise is one of the most important aspects of caring for a Border Collie. The herding dog breed has had over a hundred years of genetic reinforcement (to strengthen) to provide them with intelligence, agility, and a high energy level to perform a job (wrangling sheep) that they generally no longer have to do. This is why Border Collies are not recommended for pet owners who may be unable to provide their dogs with high amounts of exercise.
