Saw this on Huffington Post today. It was uploaded to YouTube three years ago, but it’s new to me. I’ve never seen behavior like this with more than two dogs, and then only for a few seconds. But with the world’s smartest breed, I suppose anything is possible.

wow
How funny…Molly could be one of those dogs – she has similar behavior at dog parks with her friends – I didn’t realize it might be genetic or instinct
Border collies are so smart – you definitely have to keep ahead of them – and give them a job or create one for themselves.
Thanks for the fun
Apparently playing and practicing stalking/herding skills at the same time?
That is absolutely fantastic, PT. MAde my Sunday morning. Thanks!
Way cool. I liked it. The first two dogs doing “the collie walk” reminded me of coyote behavior.
