A dog's seeing eye dog - Lily is a Great Dane that has been blind since a bizarre medical condition required that she have both eyes removed. For the last 5 years, Maddison, another Great Dane, has been her sight. This story literally melts my heart
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).
