My mother raised border collies. When the electric company wanted to move a couple hundred sheep they used to keep power lines clear across a super highway they used her border collies plus others to do it. The state troopers stopped traffic and it was amazing to watch those dogs herd those sheep.
Those are some great canines... I grew up with full sized Collies (Lady, Dutchess and K.C.), and they are remarkably smart dogs ...... the Border Collies are a very agile breed, fast and they love what they do ...
That was fantastic. I have a friend that is an animal trainer and last week I saw a picture of her and her dog getting on an airplane. Someone asked her if the dog sat in her lap. She said no the dog has it's own seat and it is always first class. She said fortunately her, Willie the dog, has to have a handler.
I watched a documentary on working dogs. One piece was taken in New Zealand in the mountains. The Shepard was an old fella and had one dog next to him. The sheep and other dogs were way down in a valley. He would whistle the commands and the dog next to him would bark at the dogs in the valley the commands he gave. Amazing intelligence. Worst thing that can be done to these dogs is pen them up or tie them up.
