In the bustling streets of New York, Katie rescues Max, an adorable abandoned puppy, and everything is peachy. But, suddenly, Katie ruins everything by bringing home Duke: a giant, furry, and sloppy stray dog. And just like that, the fine balance of life is ruined in an instant, as both dogs lose their collars, and end up in the sewers--the kingdom of Snowball: a spotless, fluffy, magician bunny, and his army of flushed pets. Now, Max and Duke must set their differences aside to survive the harsh city life, as Max's friend, Gidget, assembles a posse of old companions determined to save the two strays, and bring them back home. Will they find them in time?—Nick Riganas
