Going Next Saturday The 15th To Gettysburg Pa. To Pick up a new black lab female pup. This is about 3 hours drive for us. I was just going to let her ride home in the back seat of my truck with my 2 kids. Figure on having to make a few pee breaks along the turnpike but am I forgetting anything?? We had a lab when I was a kid that got really sick riding in a vehicle. Thanks for any help.
