A little puppy is turning into a big problem! 

 

Nancy's wish has finally come true: she has a dog of her own. She's a chocolate-colored Labrador retriever, and she's fun and friendly and loves to play. But the pup's also in a sticky situation—and it's up to Nancy to save her. 

 

Hannah's fresh-baked muffins have vanished, and a food thief is loose in the neighborhood. And guess who's getting blamed? Nancy's new puppy. It's so unfair, and she's going to prove it … by finding the real thief!
