Border Terriers are active dogs with a high energy level. This should be considered when thinking about a Border and children. Plenty of play and exercise is a necessity for BTs. A long walk or vigorous play within the yard for 20-30 minutes a day will keep your BT happy and fit. Borders also enjoy various activities such as flyball, agility, earthdog tests, tracking and obedience classes. Above all else, your BT likes being with you.
