Portia has overcome a lot in life. Born with Down syndrome, Portia has been through many surgeries, lots of doctor's appointments, and strange looks from people who want to limit what she can do. Inside herself, Portia knows she can do anything – including getting over her fear of dogs. But when Penny shows up at Portia's house, she isn't so sure. After all, Penny is a pit bull – the scariest dogs of all, right? Good thing Penny has a few tricks of her own to win Portia's trust. 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.
