Which 2019 animated sequel sees terrier Max dealing with new anxieties after his owner has a baby, while his friends explore their own adventures, including Gidget trying to rescue a toy from a cat-filled apartment and Snowball pretending to be a superhero?

The 2019 animated film that centers on terrier Max's new anxieties after his owner has a baby, while his friends embark on their own adventures, is "The Secret Life of Pets 2 (Review)." This sequel to the popular 2016 movie delves deeper into the emotional lives of our beloved animal companions. The main storyline follows Max as he grapples with becoming overly protective of his owner Katie's new son, Liam, leading him to develop a nervous itch and even wear a dog cone.

Meanwhile, Max's friends (Review) have their own escapades. Gidget, the fluffy Pomeranian, finds herself on a daring mission to retrieve Max's favorite toy, Busy Bee, after it accidentally ends up in a cat-filled apartment belonging to a "crazy Cat Lady." With some "cat lessons" from Chloe the cat, Gidget bravely infiltrates the feline domain. Simultaneously, the lovable but eccentric rabbit Snowball, who now fancies himself a superhero, is recruited by a Shih Tzu named Daisy to rescue a white tiger cub named Hu from a cruel circus owner.
