Border collies usually live 12 to 15 years. However, some border collies have been known to live for a little longer, up to 17 years.
Border collies are highly intelligent. They are very energetic and require considerable daily activity, both physical and mental, to be happy. In households that do not provide these types to stimulation, border collies are prone to develop several bad habits, such as destructive biting and chewing or digging holes out of boredom. They also have very strong herding instincts, making them difficult to keep if a household has small children. A border collie may try to herd a human child, which may include nipping and gripping with the teeth.
