i have never had a problem with mine until i got the newest member of our family the little chinese crested, but she is a little bit scared of the big ones still, all mine are crate trained anyway so they all go in a crate when im out, but when i go to bed the 2 big dogs and the pup sleep downstairs and have the run of downstairs and the chinese crested comes to bed with me, not because my others are mean its just as she is still wary she is better out the way as she tends to grumble at the bigger ones,
