I travel with my 80 pound GSD all the time in my Agile. I have a rug/dog bed right behind the cab, and she either hangs out there or on the back bed while driving. At night she sleeps in her bed on the floor, again behind the cab. She's a big dog, so if I need to move about the coach I tell her to just get back on the back bed. If my husband is with me it does get a little interesting! I do worry about leaving her for extended times. I'm comfortable with about an hour, and she's ok with that. If it's hot I can leave the air on and the voltstart in my Agile will kick in if the battery gets too low. I do need to frequently vacuum, GSD's are sheddars and the hair will quickly take over the coach!
