The Invisible Harry

Eleven-year-old Billie Stoner discovers a homeless puppy and, despite her mother's strict no-pets rule, decides to keep him, naming him Harry. To hide the dog from her mother, she enlists her scientific friend Jody, who builds a device that renders Harry invisible. With the pup unseen, Billie must navigate the mischievous chaos he causes throughout their apartment building, from knocked-over vases to secret midnight runs. As the invisible dog creates more trouble, Billie races to find a way to manage a pet no one can see.
