Welcome to Yorkie Talk. Is she excited or nervous when she rides in the car? I have to admit, my boys are a little animated in the car and have devised a naughty barking game. They compete to see who can spot a motorcycle, school bus, or UPS truck first and then bark like crazy at it.
They are tethered in their elevated seat and cannot move, but I wish they would settle down and just enjoy the ride more quietly.
