Our two very large dogs travelled with us for many years. They were both used to having a crate, (we used soft crates), and travelling in them. We just put the two soft crates on the bed in the back, left the doors open, and they would just jump in and lay down when we were in motion. They both could sna would occasionally, jump down and come visit for a few minutes, then back to their bed in the crate. Overall, when travelling, they both were much more comfortable and comfident in their crates. At times, both tried riding either on the floor, or curled up on the couch. but were uncomfortable with the motion and trying to keep from rolling round with the coach motion.
