Border collies know the way home

Because dogs have a strong sense of territory, they usually leave their own scent to help them find their way, which is equivalent to walking a distance. After urinating for a while, you will often see dogs urinating on the road. This kind of "stinky trace" means that it can help you find your way home and return home by relying on the smell you left behind. Therefore, border collie dogs can know the way home.
