One thing I've noticed about Ranger is that he loses focus easily anytime there is a change in routine or something is different--like having someone else around when he's accustomed to it just being me during a training session. I think that will go away with age and exposure, but it will take time.
The video gets choppy near the end--the camera started cutting out for some reason.
He is really in the habit of blocking or trying to push his way into me with his shoulder, particularly on his left side. I spent a good 10 minutes today just asking him to move his left shoulder away before he willingly moved it away and kept it away.
