10. Border Collies have hearing that's hard to realize.
They can hear for literally miles depending on the background, that's their job in the field. I have a Flat Coat Retriever that can hear when my wife is driving home. When she is about 8 blocks away and around a corner, he gets up and waits at the door till she drives up. You can rely on him to let you know when she is a couple of minutes away. Its urban here and a lot of traffic and he knows the difference between our car and all the other cars. It's pretty amazing.
