My children enjoyed a book when they were little that was all about a young bear climbing into a box. The entire story was all the ways the box was tipped and moved when the adult bears didn’t know he was inside.
Several years ago, a friend and I watched a canine version of this story.
This is a portion of the equipment set-up for agility trials.
Handlers jog/run alongside the dogs, directing and encouraging the animal. Many of the dogs, especially the herding breeds and retrievers, galloped over, under, around, and through the obstacles with a smile on their canine faces. I do believe several of them were asking at the end — can we do it again? Please? What fun!
The handlers, while many looked pleased with their animals, did not impress as wanting to turn around and run the course again.
