How long do border collies live?
Genetics and environment are factors in the longevity of any dog. If the border collie has been given plenty of exercise, good food, consistent vet care and a happy home, 13-15 years is its average life expectancy. The Guinness Book of Records says that the longest-lived dog was a Border Collie in England, by the name of Taffy. She lived to be 26 years old. The Border Collie tends to mature slowly and remains an active dog later in its life. They typically start acting like an adult when they reach the age of 3-4 years old and will tend to act middle-aged around 10 years old. Old age will come quickly, but some will remain active within one year of death.
