A Dog's Life — Diana G. Gallagher

Michelle has decided to enter Comet in a local dog show. But Rachel Tilly, a snooty girl in Michelle's class, insists Comet will never win. Michelle is determined to prove her wrong. But the more Michelle trains Comet, the less he seems to follow her commands. Will Michelle be able to turn Comet into a superstar dog by show time?

Stephanie's excited about the dog show, too. She's helping get Comet ready by taking him for long runs in the park. At the park, Stephanie meets a cute by named CJ, who asks Stephanie on a date. Awesome! Until Stephanie finds out that CJ has a big secret -- one that could turn her best friend into her worst enemy!
