Our border collie walks and looks at things just like that. She's really growing into herself now. Much more affable round the house than she has been. I just walk her miles and throw her a frisbee, and apart from sit and stay and come back here, I can't get her to do much. She just trots alongside and breaks off to investigate things as she sees fit. The kids, on the other hand, take her to gym classes and can get her to do handstands whilst balancing a Turbot on her nose and blowing the Star Wars theme on a harmonica. (It is actually pretty impressive to see)
But, the other day, I was out in the park and I noticed she was chasing one particular dog that all the others had been running around after. She brought that dog to me, and all the others followed. So, I got a little insight into sheepdog tactics. I was surrounded by easily fifteen dogs, and she just trotted round making sure that everything was as she thought it should be. Also, she saw off this pretty aggressive sort of Sitka/Husky cross thing. Burly bugger all full of itself and its right to everything. At first our girl just rolled over. But then I think she must have got the measure of him and she stared him down. Looked exactly like that cattle dog in Santaman's video did.
