As much fun as it it to watch a herding dog racing around, perhaps yours is more impressive. The animals in the video were looking stressed by the chase. More than likely they have been herded into that door so many times they would go there all by themselves when calmly herded in that general direction. Instead 3 ended up on the wrong side of the wall and had to be rounded up.
No matter how many times I watch the dogs 'Working', I am always amazed and awe-struck at their abilities and the dedication of their handlers/owners.
