We too have a whiner in the car.
She is a rescue and right now she is in obedience school. Not so much for the obedience training but for socialization with other dogs. On the way to the class she whines, on the way home she is so happy and content that she doesn't make a peep. DH takes her for a 4 kilo walk before they get in the vehicle to go to class.
Ben Max if you have some things I could try to help with the whining, I would really like to hear from you.
In regards to the cuz, if he is a chewer, he will chew the ears or feet off the cuz. My Stoney never did but Greta GSD rescue does. We even had to get her the black large kong, she takes months before she can destroy that. I am really lucky she does not chew my things.
Good luck, he sure is a beauty.
