The other day we happened on a field where a young man was working with his lovely border collie. I think the dog is in training as it took him a number of tries to get the sheep going in the right direction.
Then the sheep would veer off, and the trainer would whistle another command. The dog would move off in a different direction to try again.
Below you can see the collie moving fast on the outside to try outflanking the sheep to turn them.This happened several times as they kept getting away. But the dog was enjoying every moment of it. Just look at the huge smile on his face.
Finally everything went right and dog was able to drive the four sheep through the gate. You can see the boy opening the gate to let them in. Here the dog is in a "down" and the sheep are moving well.
If I'd had the time and money I would have loved to do this work with my dog Geordie. He has a strong herding instinct and we did spend a weekend learning the basics a few years ago. Sadly, without land or sheep it would only have been an expensive hobby and I decided not to pursue it. But it's wonderful to watch it when the chance arises.
By the way, Geordie loves sheep, but my other dog Maggie doesn't even seem to notice them. For her it's all about the tennis ball or the frisbee.
