Dubbed in Slovenian.
In the heart of Manhattan, a pampered Terrier, Max, has an ideal relationship with his adopted owner, Katie. Until big-hearted Katie brings home another rescue—a giant, fluffy, unruly mongrel named Duke. Max is stunned when Katie tells him Duke’s his new brother, especially when Duke immediately takes liberties with Max’s toys and bed, assuming that he and his new brother are going to share this comfortable life together.
As insecure Max tries to hold on to his turf, Duke—who’s really a sweet dog that’s been through rough times—doesn’t understand Max’s rebuff and feels anxious that Max is trying to get rid of him. The one thing Duke knows is that he can’t go back to the pound from which he just barely escaped.
This conflict escalates out into the streets, eventually landing them locked up in an animal control van and on their way to the pound. But when an adorable, but deranged, bunny named Snowball—who’s the leader of a gang of former pets abandoned by their owners, who call themselves the Flushed Pets—breaks into the van to rescue one of his gang, Max and Duke see their chance and negotiate their freedom.
In exchange, Snowball demands that they serve him in his army of Flushed Pets and live with them in their lair in the sewers—plotting revenge on the humans that abandoned them.
Once Snowball discovers Max and Duke have an owner they love and live in the lap of luxury, he unleashes his gang to pursue them throughout New York City. Forced to tap into their primal instincts to survive, these unlikely new brothers must navigate the wilds of the urban jungle and make it home safe…all before Katie returns.
