Mishmash is a very friendly dog. When he moves like a cyclone into Pete's heart, his family's new house, and the neighbor's gardens, life will never be the same! But when Mishmash's well-intentioned enthusiasm leads to messy garages and ruined gardens, it's too much for the grownups to tolerate. Pete realizes Mish must go. How he finds a new home for Mish and gives his favorite teacher a wonderful gift all in one accidental gesture makes for a hilarious, lovable story.

To Pete, the end of the world is beginning to look like a very good thing. And all the better if it comes before Monday -- before the test and before the substitute teacher blames him for that incident with the aquarium or for stealing back his big, black, overly-friendly dog, Mishmash. How Pete solves his problems with Mishmash and the substitute teacher is a story that will tickle any young reader who has ever had difficulties with tests, teachers, or dogs.
