Being a dog owner myself, does the dog's head hit the roof when the seats are in the down position? Also, when the seats are down, does the carpeting on the back of the seat extend onto the rear deck area. In the betas, there was a gap when the seats were down whereas most manufacturers have a sliding carpet section that covers the gap when seats are down. Thanks for a first look, my four legged friend will definitely be riding along with me in my S as well.
