Thanks for responding. I never thought about the spine issues, but will certainly keep that in mind.

Sasha, the 4-year-old, does try to get in bed during the night, but I am a light sleeper and will firmly tell her off and go to her bed. I am actually surprised at how well they have adapted to their new bed and I am loving the extra space.

Even though I love the extra space, I hope my dogs feelings aren't too hurt. They are both so sweet and good natured. I know that they just want to be close to us.
