That all being said, in our house, Piper sleeps in his dog bed on the floor and Murray now sleeps in bed with us. We raised both dogs to sleep in their crates (which we kept in our bedroom) from 8 weeks old until about 2 years old. It was not only for their safety, but they actually preferred sleeping in their own space. By 2 years old, I was ready to remove crates from my bedroom and regain some space, and at that point, they could be trusted not to wander around and hurt themselves too. They both then slept in dog beds on the floor in the bedroom. We knew as a puppy, Piper could never be an "on the bed" sleeper. He had dominance issues from a very early age and snarled and growled whenever we asked him to get off the bed. So, he was trained to sleep on the floor. Murray used to sneak up on our bed in the middle of the night, and he'd just be there when we woke in the morning. We eventually gave up that game, and allowed him to come and go as he pleased...and he pleases to be on our bed now all night!
