I don't think there is a yorkie in the world that doesn't hog the bed! I've never had more than ten inches of bed in my life.
Kacee's preferable spot is sleeping stretched out along the side of a pillow. Sometimes she likes to sleep between the pillows. When she gets cold, she wants to cuddle and get under the covers squished up against me and that's how I end up with ten inches at the edge of the bed.
