Karen's New Puppy
by Ann M. Martin
When Karen's dog, Midgie, runs away, she gets Sadie, a new puppy who's adorable--but out of control. Sadie isn't trained, doesn't get along with Rocky the cat, and requires a lot of work. After much thought, Karen's family decides they must find a new home for Sadie. Just when everyone is at their wit's end, Midige returns.
