There was once a dog who had no name, and he had no home. What he did have was fleas, but they weren't much company. The dog longs for a family. At last he sees one that looks just right - with a brother and sister to play with him. He follows them around everywhere but they shoo him away. It's not till the little boy runs away from home, that Fleabag (as they call him) can finally win his way into their hearts - and home.
