Binks is 14 weeks and sleeps with my 15 year old daughter in her bed, unless its a weekend and shes got company and is staying up late, then I take him to bed with us, He hasn't ever had an accident in the bed and sleeps all night.
My poodle Tigger has always slept with us, though unlike Binks he won't sleep anywhere but at our feet, Binks likes to curl up near your chest.
They are so spoiled.
