Maryâs new in town. Sheâs worried about starting classes at her new school. Thatâs why her mom called the Helper Hounds â and why Sparkplug, the wildly handsome, wickedly smart, card-carrying, world famous Helper Hound is on the scene. Sparky knows a thing or two about moving. He moved four times as a puppy, and learned to make new friends along the way. Sparky knows he can teach Mary all his best tricks and help her meet new friends, too. At least Sparky thought he could until he met Custard, Maryâs persnickety cat. Will Sparkyâs best tricks be enough to win over Custard and show Mary making friends is nothing to fear? Helper Hounds are uncommon heroes with wet noses and big hearts. Each book focuses on a different emotional support dog and how they help kids process and overcome emotional challenges.
