Well, what a nice surprise! “The Secret Life of Pets 2” is a vast improvement over the original, which had a promising beginning but ended up with a lackluster imitation of “Toy Story.” This sequel combines three different stories and adds some terrific new characters all in a zippy under 90 minutes. It is colorful, exciting, and a lot of fun.

Our hero is still Max (Patton Oswalt, taking over from Louis CK), a lovable mutt who does not like change but has made his peace with his new apartment-mate, Duke (Eric Stonestreet). But more change is ahead. Max’s owner (that is what he calls her) Katie (Ellie Kemper) meets Chuck (Pete Holmes) and soon there is another new resident in the apartment, a baby named Liam. Max, who thinks he does not like children, cannot resist the baby who clearly adores the two dogs. But the changes are very stressful, and when his anxiety about keeping Liam safe is so severe he has to be taken to the vet and finds himself in the Cone of Shame, to keep him from scratching all the time.

Katie and Chuck take Liam and the dogs to visit their family on a farm. Max asks Gidget (Jenny Slate) to watch his favorite toy, Busy Bee, while they are away. (Fans of “Best in Show” will remember Parker Posey’s frantic search for a dog toy called Busy Bee on the day of the dog show.) Gidget, whose unrequited crush on Max is the movie’s weakest plot point, agrees, but almost immediately manages to knock it out of the window, and it lands in the apartment of the cat lady to beat all cat ladies.

Meanwhile, Snowball (Kevin Hart), a soft, fluffy white bunny whose little girl owner dresses him as a superhero, begins to believe he really is one, and when newcomer Daisy (a terrific Tiffany Haddish) asks him for help freeing a friend of hers who is being abused, he is happy to agree. The friend is Hu, a white Chinese tiger, and he is in a cage at a circus, guarded by wolves.

Max will get some guidance on dealing with his fears from a wise farm dog named Rooster (Harrison Ford!! At his Harrison Ford-iest, which is awesome!). Gidget will have to get cat lessons from the languid pudgeball Chloe (Lake Bell) on how to be a cat so she can go undercover to get Busy Bee back, in the movie’s best scenes. And Snowball and Daisy will have a lot of wild adventures along the way.

It all moves along with brisk good humor and some nice lessons about how to handle being scared and what we learn when doing what scares us gives us the chance to be surprised at what we can do. The design of the characters and settings is witty and engaging enough to invite repeat viewings. Parents may need to talk to their kids about some of the plot points — we don’t want anyone trying to let a tiger out of the cage, sometimes it makes sense to listen to your fears and not take risks, and kids should know there are laws protecting animals from the abuse Hu suffers. But this is a treat for the family that makes me hope number three is in the works.

Parents should know that this film includes comic/fantasy/action peril and violence including very dangerous stunts, a protracted fistfight, and a man who threatens animals with a whip and a gun, some potty humor and schoolyard language, and a cat becomes intoxicated on catnip.

Family discussion: What did Max learn from Rooster? Why did Rooster give him a bandana? Was there a time you pretended to be braver than you felt? Why did Max change his mind about Liam? Which pet in this film would you like to have?
