Nancy and her friends save a dog shelter’s big day in the thirteenth book in the interactive Nancy Drew Clue Book mystery series.

Helga and Horatio are getting married! The bride and groom are two fluffy white dogs belonging to one of River Heights’s more eccentric citizens, Mrs. Ainsworth. Mayor Strong’s mansion is decorated for the occasion, and the whole town is invited. The celebration is an effort to raise awareness for Waggamuffins, the local pet shelter. And Nancy, Bess, and George are helping out by walking three adoptable dogs down the aisle.

But the wedding comes to a barking halt when the bride and groom are found covered in sticky paint! Mrs. Ainsworth is so upset she calls off the whole thing and demands to know who is behind this color conundrum. But if the guests leave early, how will they meet all the cuddly canines that still need homes?

Can the Clue Crew solve the case of the painted pups before it’s too late? It’s up to the Clue Crew—and you—to find out!
