Didn't really have one that stuck in my mind so I thought of the Carl books. Rotties are a favorite dog of mine and Carl is a good example of the loving side of the breed.
If you are familiar with the books there is very little text but a small story mainly told through beautiful illustrations. In most of the books Carl and baby Madeleine are left alone by mom and off they go to have good times.
The story is simple with your own imagination filling in what you want. Sweet, loving, warm. Yes, I think Carl is a good bedtime story.
