I started out separating them when we were not home, but Tucker just couldn't handle being *alone*, even though there was just a board that kept him in the kitchen. So after a month or so they were both allowed the freedom of the house together. It was a leap of faith and to help Tucker alleviate his separation anxiety. Fortunately, it worked out well. They have had just a couple spats where they had to be separated in the years they have been together, but those occurred while I was home. I think that when we are gone, they are more inclined to sleep.
