Once again, the perfect helpful article. Sounds like the best way is to notice when he starts and say no, and distract him. It is so fascinating to see behaviors just pop up out of nowhere. He's never seen that and as it says he has no sex hormones to drive him. I remember how I was amazed when a friend's Lab gave birth (her first and an only dog) how she knew just what to do at birth and then how to move it around from spot to spot. Pure inborn instinct, no aunts or mom dog to show how it's done. Funny that this not the case with human mom's and their first. Thanks again!
