I have a friend who rescues border collies. It cracks me up when a group of us will be standing up chatting together at her house and we suddenly realizer we are in this little tight group. Her dog does to us what herding dogs do, he nudges and leans on us until we are really close together. Funny thing is we don’t even tend to notice it until we’re tight as sardines, but then we have a good laugh.
They’re great dogs. I have a border collie mix, she doesn’t try to herd people but she will try to herd up deer in my yard or a park. Never succeeded yet, but she still tries.
