This breed is intelligent, responsive, and devoted to their master and work. The Border Collie is extremely sensitive and thrives on human interaction. They do need plenty of exercise though. What seems to be the problem?
Speaking from experience here. . .don't let this behavior continue. It's annoying, and hard hard to break if you let it continue. I thought it was "funny and cute" with Blaze, but it's not. It's annoying and very soon carries over to other things.
I let it continue and it was a mistake made that won't be made again. We're still having a tough time breaking it.
