"My dog Sam has a superpower. He doesn't wear a costume. He can't fly. And he definitely can't make himself invisible. Sam's superpower is happiness." Sam can find happiness in the most unexpected places: a smelly old boot, a deflated ball, even in a muddy puddle! When Dad leaves for work, Sam's young owner needs a little help to be happy again. Can Sam show his best friend how to be a bit less sad and a bit more dog? This is a funny and heart-warming picture book about finding joy in the simplest things. With uplifting text from Caroline Crowe and engaging, lively illustrations from Carlos Velez, this feel-good story celebrates the connection between children and pets and encourages us all to be more dog!
