The moment I saw that pic, that sappy song "All by Myself" started playing in my head.
Poor little Bella. The bed's probably all lumpy in the middle and that's why she had to lay on the edge. It's so sad to see a princess with nobody to snuggle with. I vote for at least 3 more chihuahuas. You need your stretching room in a bed that big so more than 3 would make it way too crowded.
