Reading dogs help children learn to read and practice reading aloud. April 23 is World Book Day, when UNESCO draws attention to the importance of books in disseminating ideas and knowledge.

A dog has the effect that you relax and the dog does not sigh or point out if you read incorrectly, says Pernilla Sjöqvist, dog handler and owner of Lija. The reading dog is always fully booked when she arrives at the city library in Karlstad, Värmland.
