Harry the dog (Zion)

When a white dog with black spots runs away from home, he gets so dirty his family doesn't recognize him as a black dog with white spots.

"Harry, the mischievous little white dog with black spots, isn't happy when the children are paying more attention to the neighbor's guinea pig than him. But when Harry accidentally causes the guinea pig to get loose at school, he has to use his detective skills to save the day. Can Harry find the guinea pig before he's sent to the doghouse?"--
