My Chocolate Lab (Colt) is 21 Months. I don't know why he wines and barks, but every time I tell him to load, Boom he loads in his crate with excitement. With T4R running parked or not running and parked he's ok... but soon as I put it in Drive and start rolling he starts to bark, wine and pant uncontrollably. From a short ride to a long ride he does it in or out of his crate. But soon as I let him out to run his ass off he will be fine once back in his crate and driving again.
Same thing happens when sitting next to me in the pickup.
He road his first 7 months with me in my big rig and never did that.
It can get loud and irritating so I make sure I take my Bose headphones.
