I see it could be two ways. One: the big dog is very kind and left the big bed for the pup. Two: the pup went on the big bed and left the small bed for the big dog. In that case, if I was the big dog, I would just lay on the small dog (or around it).
My dog knows our routine when we are leaving and runs to her "bye bye spot". She will give a kiss to the person to leave but always does this to the person. I guess she hopes they wont leave without a kiss. I'M DYING! I CAN'T lol So sweet.
