Border Collies come from the hills along the Anglo-Scottish border, where shepherds wanted a dog that could gather and move sheep with speed, focus and very little instruction. Today's dogs are medium-sized, usually 30 to 55 pounds, with a rough or smooth double coat. Black and white is the best known, but they come in many colors and patterns.
Many are quick, eager learners that bond closely with their people, and that intelligence needs an outlet. Without daily exercise and mental work, a Border Collie may invent its own jobs, like herding children or chasing cars. Each dog varies, so look at how the dog behaves, not just the breed. Lifespans run 12 to 15 years, so adopting one is a long commitment.
