2 90 lbs female german shepherds here. they travel everywhere with us. the fur gets everywhere if you get behind on clean up, but the dogs are well behaved as i've been training/working them in schutzhund since they were 6 weeks old. now they are almost 7 years old.
when we leave them in the coach, they just sleep i think... nothing gets messed up, they don't bark unless someone knocks on the door. very well behaved.
i do get in trouble a lot for taking them off leash. but they are on voice control no matter what the distraction (benefits of all that training). my dogs are better behaved than most people's kids at the campgrounds...
