This thesis aims to investigate why reading out loud to a reading dog works as a reading promotion action. The focus lies at children from pre-school to middle school in Sweden. The theory that is used is Maslows A theory of human motivation. It is especially the three last steps that are used; love, esteem and self-actualization. The method to collect information was semi-structured interviews with six persons. Two librarians and four dog handlers. What I found was that the three last steps in Maslows theory were fulfilled. This means that this thesis shows that reading loud to a dog works as a reading promotion action because Maslows steps were fulfilled. Important to know is that this study was small and that further studies needs to be conducted to confirme this thesis results.
