We have Cavalier King Charles Spaniels, which were originally referred to as comfort spaniels. They were bred for the upper classes to provide companionship and warmth in castles.
Today they can be trained to work, for example retrieving water fowl, but they are happiest sleeping at your feet or in your lap.
Ours are cheerful clowns/couch potatoes.
Have a friend that raises them. Really nice dispositions.
