How long does a border collie usually live?   12 to 15 years, usually. Some live 16 - 17 - 18.... up to 20 years! Border collies, being a medium sized breed, should have an average lifespan of 15 years.
I personally know Borders that have lived to 18 and 19 years old, but they are very few. Most live to about 14 to 17 barring accidents (like cars). BTW, the article on the dogtime site is a very poor one on Border Terriers.
