Do your dogs sleep in your bed with you?

Although my dogs do not currently sleep in my bed, they used to sleep with me every night. I can understand the comfort that comes with having your dogs with you throughout the night, but it can get a bit much when there are three huge dogs at the foot of your bed. I became tired of having to worry about them fighting throughout the night. I also was becoming itchy due to their shedding. They slowly became used to sleeping on the floor, but every once in a while my German Shepard will try and sneak onto the foot of my bed. I don't see anything wrong with it, except the fact that they can be dirty at times.
