This is also an excellent example of providing breed-adequate enrichment, because Border Collies are herding dogs. They were bred to run a lot and do multiple quick and sharp turns, so if you can’t provide your collie with an actual herd of animals to… well… herd, an obstacle course like this is a great alternative. That dog is having the time of her life.
the social norm of “its your ethical responsibility to be constantly aware of, and angry about, every bad thing happening in the world at all times, even if you can’t possibly do anything about it” is possibly the best way I can imagine to create burnout and cynicism and depression in a population, so good job guys
