Off the leash ... again! Max's life gets turned upsidedown when his owner gets married and has a baby. The overprotective pet falls tail over collar for the kid, and on a trip to the countryside with his human family, he can't help but see danger lurking behind every cow, turkey, and tree. Can an old farm dog teach Max to find his true animal nature -- and to just relax? Meanwhile, Gidget goes on an undercover mission as a cat, and snowball takes to the street as a masked superhero. And those are just the beginnings of the adventures.
