In the meantime, one very effective way to hold a Border Collie still is the trick of holding the ball like you're just about to fling it. This worked great with Shimmer (my last stock dog) when my arm was tired of flinging stuff. That keeps him still for quite awhile! Below, you see a dog poised to go like a loaded spring! He is so fast, sometimes he catches the ball in his mouth before he realizes it, and looks around for it briefly, then realizes it's IN his mouth!! Funny boy!
Then comes the "big lean", where he leans way over his center of gravity, in anticipation of the chase. The more intense it becomes, the higher his tail goes and the bigger around his eyes get. Sometimes his whiskers twitch in the intensity of it! Here, we are just getting started in the "big lean". While he is doing this, he is frozen still...for however long it takes. That's what I love about Border Collies! They take their jobs so seriously and they are the masters of concentration! They make great examples to my human students on how to tune things out and concentrate.
Notice Swifty's ears in the above picture? Shimmer went through this phase when she was this age as a pup. I call it the "flying nun" phase! See how his ears are nearly straight out and seemingly weightless? So cute! Such a puppy look!
Eventually, he settles down. Confession. Keeping him off the sofa......just doesn't work! Why? Me. I was thinking about that last night. Poor Rollie and Simon (our Collie and Sheltie) were never allowed on this sofa. It saddened them, but they accepted it. Here now is Swifty, and he thinks the sofa is just for him! Makes for some emotions. What am I doing?? I let him go up there and I'm not sure why.
PS...owls are hooting a lot, and calling back and forth! So relaxing at night to hear them all around!
