Border Collies were developed by shepherds along the Anglo-Scottish border to gather sheep with speed, focus and very little instruction. They're medium-sized, usually 30 to 55 pounds, with rough or smooth double coats, most often black and white, and an intense stare called "eye" that comes from stalking stock. Many are quick, eager learners.
In Springfield, that brain needs an outlet beyond a lap around the block. Plan on training games, fetch and puzzle toys, plus a securely fenced yard or solid leash habits, since many Border Collies chase bikes, cars or children. Each dog differs, though: some are laid-back and others are intense, and a dog's age and background shape how much activity suits your household.
