aga of an Australian shepherd who meets her soul mate: a struggling musician, Scott, with dreams of spreading love on stages across the globe. When Scott's work starts to pay off, Cocoa wanders onstage herself and finds sudden fame--and the two of them embark on an adventure that takes them around the world playing music, delighting fans, and ignoring leash laws.

But as the pace of life quickens, Cocoa begins to feel worn out--she misses the simpler times, and she's no longer seeing the world with puppy eyes. Luckily, Scott has just the thing to restore Cocoa's sense of wonder: a little sister dog. The two of them set off on an adventure to add Molly to the family, and soon Cocoa is teaching the puppy all about life on the road . . . and even how to take it to the stage.
