Friends Sydney, girl with a love of fashion, and Sidney, boy with a love of sports, team up to convince their parents they are responsible enough to have a dog for a pet  With two other friends, they start a dog-walking business.  Almost immediately, they hit snags.  A business requires a lot of their time and consists of smaller jobs that are not so much fun – creating advertising posters, picking up the poop, making fair schedules.  Keeping their friendship and convincing their parents they can care for a pet is almost more than they can handle.  Both Sydney and Sidney tell the story in alternating chapters, working through all the big dog decisions.
