No idea really. I was told chows can turn on you around 3 years old or if they go through that age they will be fine. I had a female that was always a
big baby. He was fine and laid down and went to sleep and when he woke up he turned crazy. And he was laying by me, but went to the wife and started
growling at her.. If it was a dominance thing I would think it would have been me he came to since I trained and dealt with him. Maybe not.
