Border collies are affectionate and active dogs. The breed is intelligent and learns quickly. Border Collies are protective of their family and territory and make excellent watchdogs. They can sometimes be snappy with strangers, nipping at the heels the same way they would nip at sheep if herding. Border collies are extremely energetic dogs and must have the opportunity to get lots of exercise. They love to run. They should be socialized well from the time they are young and should have obedience training. Border collies are considered average shedders but require brushing on a weekly basis.
