When Emma s little brother loses the neighbor s dog, the girls must work together to track her down in the latest addition to the Cupcake Diaries series.

When the girls bake cupcakes for a big Adopt a Pet fundraiser, Emma s little brother Jake decides he wants to get a puppy! At first it seems like a really sweet idea, especially when Mia says Jake can walk and groom her two dogs to get used to what needs to be done. But when a neighbor goes on vacation and leaves Jake in charge of his four-legged friend and the dog goes missing, the girls realize perhaps Jake is still too young for a pet. Will the girls find the missing pup before her owner returns?"
