We had our first training session today. It went fairly well. I did end up with two bite marks on my hand, just one more than I thought I would get. He only tried twice to jump up on me, he was corrected appropriately. The biting is a concern as he bit harder when I corrected him for it. I talked to the owner at length about this. There is a difference between being puppy mouthy and biting down.
He got scared of me, and that was okay. He should be respectful of her as his owner. He isn't. He is now respectful of me
He was as he should be submissive to my big boy magic and ok with the wee one razzle.
