Here's what I love about dogs. They aren't careful not to disturb you. They don't overthink. They jump on the bed or the sofa or the chair and plop down. They come and they go. I'm not sure they love me exactly, but they count on me because I am a source of heat and food and pleasure and affection. If one of them is lying next to me and suddenly prefers the sofa, I don't take it personally. Dogs don't wake up on the wrong side of the bed. There is no wrong side of the bed for a dog.
