The fur flies when canines and felines face off in this imaginative, family-friendly comedy. Rookie puppy Lou (voice of Tobey Maguire) and seasoned dog Butch (voice of Alec Baldwin) lead a pooch troop against an army of nitty-gritty kitties that has hatched a purr-fect plot to steal a dog-allergy cure developed by a professor (Jeff Goldblum). Other voices include Sean Hayes and Susan Sarandon.
