Terrier Max is coping with some major life changes. His owner is now married and has a toddler, Liam. Max is so worried about protecting the boy that he develops a nervous tic. On a family trip to a farm, Max and mutt Duke encounter canine-intolerant cows, hostile foxes and a terrifying turkey, all of which only elevates Max’s anxiety. Luckily, Max gets some guidance from veteran farm dog Rooster who pushes Max to ditch his neuroses, find his inner alpha and give Liam a little more freedom.

Meanwhile, while her owner is away, plucky Pomeranian Gidget tries to rescue Max’s favorite toy from a cat-packed apartment with a little help from her feline friend, Chloe, who has discovered the joys of catnip.

And crazy-but-cute bunny Snowball gets delusions of grandeur that he’s an actual superhero after his owner Molly starts dressing him in superhero pajamas. But when Daisy, a fearless Shih Tzu, shows up to ask for Snowball’s help on a dangerous mission, he’ll have to summon the courage to become the hero he’s only been pretending to be.

Can Max, Snowball, Gidget and the rest of the gang find the inner courage to face their biggest fears?
