Plot
Adam Sandler and Robert Smigel introduced the film by explaining 3D technology and the Collar Detector. A white Pomeranian named Gidget lives with the Toy Orchestra (consisting of the toys from the Toy Story Toons shorts Small Fry and Partysaurus Rex). While Dolphina accidentally killed a man in the pool, the Pool Patrol quarantines the water park and decapitates his head which was taken home in the basket on the backpiano. Gidget and the others thought that a man was killed and got his head decapitated, but while she thought that they were ready for a musical adventure, they hang out with mixing teddy bear engineer Ted, tabby cat Chloe, pug Mel and budgerigar Sweet Pea. One day, Max, a Jack Russell Terrier who's in love with Gidget saw his next door owner Katie adopting Duke, a large mongrel from the pound, leaving the Toy Orchestra jealous because of her divided focus on him. Mini Buzz went to check on Duke, but he accidentally caused a frenzied panic bumping and hurtling himself. The other pets and the Toy Orchestra sense her owners approaching and scatter leaving Gidget alone when they enter.

Gidget enjoys being played in the bathtub but then she dives under with a submarine who talks in a French accent. She then realizes she left the water on and it floods the bathroom. Her owners hear Gidget crying for help and opens the door letting all the water out. They then chastise Gidget for flooding the bathroom. Meanwhile, The Toy Orchestra reenacted the first spelling adventure from Endless Wordplay, until the next morning, Pirate Crab discovers that there is a thunderstorm destroying the SS Onomatopoeia. Gidget flees to save the Toy Orchestra but she falls into the water and is saved by Mini Buzz. Gidget, Mini Buzz and the Toy Orchestra helped Maria and Fernando in the La Pasión de la Pasión telenovela, then the others reenacted the second spelling adventure also from Endless Wordplay. Meanwhile, Max and Duke are both attacked by cats led by Sphynx cat Ozone who removed both dogs' collars, attached Duke's collar to the Collar Detector and left them to be caught by Animal Control. Duke fears that he will be put down if he goes back to the pound.

They are rescued by a white rabbit named Snowball, the leader of "The Flushed Pets" - a gang of sewer-dwelling animals who hate humans because their owners mistreated them. After Max and Duke pretend to despise humans as much as they do by saying they killed their owners, the Flushed Pets invite them to join. Before they can prove their loyalty by allowing a one-fanged viper to bite them, Snowball learns from the cats that Max and Duke are domesticated. The two dogs escape the sewers and board a ferry to Brooklyn, inadvertently killing the viper in the process. Snowball vows to kill them and leads the Flushed Pets after them. Meanwhile, Gidget recruits a red-tailed weather hawk named Tiberius to find him. After Gidget got a visit from her Sunny Delight blimp agent Lofty Harvey and enlisted Mel, dachshund Buddy, Chloe, guinea pig Norman and Sweet Pea, Tiberius mistakenly returns carrying Ozone who is the one who stole Max's collar. Lofty Harvey angrily blasts a tornado which sucks Gidget, Mini Buzz, Ozone, the pets and the Toy Orchestra. Gidget then breaks the fourth wall, telling the audience that they can help her find Max and attaches his collar to the Collar Detector.

Mini Buzz, Ozone and the Toy Orchestra were exiled to the Himalayas where they were taken in by a Yeti, who tells them about a nearby village which they realize that they can use to find Max. On the way, they meet Pops, an old Basset Hound, who helps Gidget, Mini Buzz, Ozone, the pets and the Toy Orchestra find Max. Mini Buzz and the Toy Orchestra parachuted on their way to find Max, but Mini Buzz accidentally falls into a Peterbilt truck named Jerry Recycled Batteries from Cars. When Jerry Recycled Batteries angrily refuses to kill Mini Buzz after he bought the mouse to use it as a bullwhip in the past Indiana Jones films, he gets dumped and changed into a sextet (consisting of a cow, a duck, a dog, a sheep, a pig and a lion). Gidget wishes she was a papaya in an episode of The Annoying Orange telling Orange, Pear, Marshmallow and the apple from the bag where Max is so she recruits Fred to join the Toy Orchestra and find him but she accidentally gets caught by Animal Control. Gidget is finally rescued by Snowball but he gets caught in the pound. Gidget then flees off to find the others.

Meanwhile, Max and Duke raid a sausage factory for food. Carl and deformed sausage Barry are horrified as they witness the other purchased foods being cooked and eaten by Dolphina disguised as a robot, shown from the foods' perspective as a brutal murder. They try to escape out a window, but Dolphina kills Carl with a knife, attempts to cook Barry, gets her disguise decapitated in a domestic accident and only succeeds to fall into the forbidden island and hit a monkey tree. Dolphina then surfs on a monkey tree back to New York, but the monkey tree gets eaten by a shark. Barry stumbles across Gidget, who becomes able to communicate with the others to find Max. When Dolphina has the monkey tree eaten, she must plot revenge on the shark and find someone under the sea to help Gidget find Max. Meanwhile, Gidget, Mini Buzz and the others get caught in a fishing net by a massive flock of seagulls. Fred and Barry order the seagulls to fly upward to the land. Meanwhile, Dolphina finds a mermaid and they all swam back to the submarine where a giant squid attacks it and the submarine goes back up to the surface to break the net, propelling the seagulls into the sea and enabling Gidget, Mini Buzz and the others to escape.

Meanwhile, Max and Duke entertain at a child's birthday party, disguised as a purple monster character named Party Marty. Duke tells Max about his previous owner, the other Fred, an elderly man who adopted him as a puppy and loved spending time with him. One day, Duke got lost while chasing a butterfly and was caught by Animal Control, but the other Fred never came to claim him. Max convinces him to visit the other Fred's house in a nearby neighborhood, but Max, Duke and the children all scared each other. Meanwhile, Gidget, Mini Buzz, Ozone, Fred, Barry, the pets and the Toy Orchestra got a visit from Santa Claus who got lost finding his way to New York City. He also tells Mini Buzz that fruit salad will help Gidget find Max.

Afterwards, Gidget, Mini Buzz, Ozone, Fred, Barry, the pets and the Toy Orchestra go to the School Science Fair to meet a little girl named Molly, one of the kids who is the last one to join the Toy Orchestra and help them find Max. She gets transported around the world with the help of the Around the World Machine. Molly wonders if she flies in a hot air balloon on the way to dreamland in her final spelling adventure, before Lofty Harvey and the media descend on the town to capture Gidget, who gets caught in an exorcism attempt by bees.

Meanwhile, Max and Duke arrived at Fred's house and Reginald learned that the other Fred was presumed dead but came back as a ghost. Heartbroken, Duke accuses Max of attempting to get rid of him and barks at the new homeowners who had just returned to the house and called Animal Control. The handlers catch Max, but Duke interferes long enough for Max to escape and ends up being captured instead. While trying to rescue Duke as he follows the Animal Control van, Max is attacked by Snowball who tries to kill him. However, when his gang is captured, Snowball realizes that he and Max must work together to rescue them. They drive a city bus into the van on the Brooklyn Bridge, stopping traffic. Lofty Harvey and the Flushed Pets encircle Max, unaware that Snowball discovers a poster for Sing which means that the next film doesn't come out until Christmas, but Gidget, Mini Buzz, Ozone, Fred, Barry, the pets and the Toy Orchestra save him. When Gidget is using her kung-fu fighting skills, Gidget starts to retrieve Max's collar back to him and fall in love.

Snowball is very angry with Lofty Harvey that the film isn't over yet and yells at the top of his lungs which causes the Flushed Pets to fall out of the cage in the van stuck in scaffolding and escape. Once Gidget got the keys to Duke's cage, the van plummets into the East River with her inside. Lofty Harvey warns Snowball that he was being petty for destroying the van and captures him with bees, but Molly and the media interrupt him. When Molly is using her kung-fu fighting skills to do the same as Gidget does, Lofty Harvey taunts and flips her off. Immediately afterward, Molly notices the keys that Gidget left and jumps into the river to retrieve them, allowing herself and Duke to escape the sinking van and return to the Brooklyn Bridge by Kathy Copter.

Once Gidget and Duke landed onto the Brooklyn Bridge after Lofty Harvey and Snowball were killed in the river, Molly tries to realize how good being heroic feels, but she got eaten by an angel shark. Max tries to express his love for Gidget, but Molly's mother weeps that her son got eaten by an angel shark. Gidget is not convinced and pushes her off the bridge and into the mouth of the angel shark. She then finally retrieves Duke's collar back to him and they all celebrate their victory. The people sang along with Mini Buzz at Lofty Harvey's funeral. Later, Max appears at Lofty Harvey's tribute, thanking everyone for saving himself and Duke and welcoming the Toy Orchestra for the final time to end the film. They posed a picture with Max and Duke saying "Cheese!" as the film ends. Smigel sobs uncontrollably that Lofty Harvey is gone.

In a mid-credits scene, Max and Duke finally reunite with Katie. The three then look over to find the ghost of Fred playing Dragon Ball Z on XBOX 36. Max asks how the Kinect works. The ghost of Fred says that the Kinect sucks balls and Tattoo crashes to the floor on the chandelier, killing Fred in the process.

Release

It was the second R-rated film to be released in 2D and 3D theatres, the first was Jackass 3D. The Secret Musical Life of Pets premiered at VidCon on June 24, 2016. The film is accompanied by the first R-rated animated short film entitled Garden Aliens.

Home media
The Secret Musical Life of Pets was released on Digital HD on November 22, 2016, and on Blu-ray, Blu-ray 3D, Ultra HD Blu-ray, and DVD on December 6, 2016. In addition to the short film Garden Aliens, which was released theatrically with the feature film, the releases also include two short films: Gidget's TV Trouble and Runaway Stand.

Box office
The Secret Musical Life of Pets grossed $368.4 million in Canada and the U.S., and $507.1 million in other countries for a worldwide total of $875.5 million, against a production budget of $75 million. Its international takings helped push Universal Pictures [International] past $1 billion for the tenth consecutive year, and aided Illumination Entertainment to pass the $4 billion mark for the first time since 2010.

Worldwide, it is the fifth highest-grossing original film of all time (behind Avatar, Zootopia, The Lion King, and Finding Nemo), the sixth highest-grossing film of 2016, the 12th highest-grossing animated film of all time, and the 50th highest-grossing film of all time. Deadline.com calculated the net profit of the film to be $374.6 million, when factoring together all expenses and revenues for the film, making it the most profitable release of 2016.

North America
In Canada and the United States, the film was projected to gross around $70 million in its opening weekend, with some predictions going as high as $100 million. It received the widest release for an animated film as well as for an R-rated film (breaking South Park: Bigger, Longer & Uncut 's record) and the seventh widest of all time overall, across 4,370 theaters, the widest release since The Dark Knight Rises. It made $5.3 million from Thursday night previews in 3,009 theaters, which is the second biggest of all time for Illumination, behind only Minions ($6.2 million), and the third biggest of all time for an animated film, behind Finding Dory ($9.2 million) and Minions. This was followed by a record-breaking $38.5 million opening day gross (including previews), the biggest for an original film. In its opening weekend, it exceeded expectations and grossed $104.4 million, finishing first at the box office. Its debut is the sixth biggest for an animated film, the sixth highest weekend debut in July, and the fourth biggest opening weekend for Universal Pictures. It also set the record for largest opening for an original film, eclipsing the $90.4 million debut of Inside Out.

In its second weekend, the film made $50.8 million (-51.3%) while maintaining the top spot, despite facing stiff competition with newcomer Ghostbusters. Although it slipped into second place when overtaken by Star Trek Beyond in its third weekend, it was still able to fend off the two other new releases—Lights Out and Ice Age: Collision Course—by earning another $29.6 million. It passed $300 million on its twenty-sixth day—the same day it crossed $400 million worldwide—becoming the seventh film of 2016, the seventh Universal Pictures film (the first for the year), and the twelfth animated film overall to reach the benchmark.

Outside North America
Internationally, The Secret Musical Life of Pets received a scattered release from June to September in a total of 69 markets, and faced competition from other animated films such as Finding Dory and Ice Age: Collision Course in the course of its release. In total, it had number-one openings in 45 markets and recorded the biggest opening for an original animated film in 17 territories, and the No. 1 animated film of 2016 to date in 13 markets. It topped the international box office in its ninth weekend after earning $43.8 million in 53 markets (dethroning Suicide Squad). However, this wasn't the film's biggest single weekend gross. Its biggest weekend gross was actually in its seventh weekend when it grossed $69.3 million. It opened at No. 3 behind Suicide Squad ($133.3 million) and the Chinese film Time Raiders ($64.6 million) that weekend.

It was released in the United Kingdom and Norway two weeks ahead of its U.S. release, where it grossed a combined total of $14.1 million in the two markets. Prior to its official debut in the UK and Ireland on June 24, the film had two days worth of previews on June 18 and 19, from which it made £3.63 million ($5.2 million) in two days. This figure was later counted in the film's official opening weekend. It went on to score the fourth biggest original animation opening weekend ever there, with £9.58 million ($13.4 million) from 592 theaters, trailing behind Inside Out, Monsters, Inc., and Up. Excluding previews, its total three-day opening was $8.1 million. This was amidst Brexit and despite facing competition from Independence Day: Resurgence. The film held off extremely well in its second and third weekend falling just 20% and 24%, earning £4.47 million ($6.1 million) and £3.62 million ($4.8 million) respectively despite facing some competitions. It has topped the box office for three consecutive weekends and has grossed total of $41 million there. In Norway, it took the number one spot as well, with $778,000. It scored the biggest animation opening of 2016 and the second biggest of all time overall in both Taiwan ($2 million)—behind Madagascar, and Hong Kong ($1.9 million)—behind Inside Out.

In Argentina, the film had a record-breaking number-one debut with $4 million from 195 screens — the biggest opening weekend ever for an animated film and the second biggest opening ever for any film (behind Furious 7). Similarly, Chile also recorded the second biggest animated opening ever with $1.7 million (behind Minions). Colombia also opened at No. 1 with a huge $1.5 million. In Mexico, other than opening at No. 1, it posted the biggest original animated opening of all time with $7.6 million, surpassing the studio's own previous record holder Inside Out. Also in Russia, it scored the biggest original animated opening and the second biggest ever for an animated film, behind Minions with $16.3 million, although this included $6.4 million five days worth of previews. It went on to become the highest-grossing film of the summer that year. In Japan, the film opened on August 11—the date of Japan's first Mountain Day national holiday—with Toho-Towa distributing, and earned $4.6 million on 370,000 admissions for its two-day opening weekend dethroning Shin Godzilla off the top spot.

Critical response
On Rotten Tomatoes, the film has an approval rating of 74% based on 200 reviews with an average rating of 6.2/10. The site's critical consensus reads, "Fast-paced, funny, and blessed with a talented voice cast, The Secret Musical Life of Pets offers a beautifully animated, cheerfully demanding musical diversion." On Metacritic, the film has a score of 61 out of 100 based on 39 critics, indicating "generally favorable reviews." Audiences polled by CinemaScore gave the film an average grade of "A–" on an A+ to F scale.

Peter Travers of Rolling Stone gave the film three out of four stars and called it "an animated fluffball-a sort of My Little Pony with pets does everything to drive you crazy and ends up being totally irresistible." Scott Tobias, writing for NPR, characterized the film's concept as "a house pet musical," highlighting the film's "thinly distinguished characters" and "gloppy sentimentality." Steven Rea of The Philadelphia Inquirer gave the film three out of four stars and said "In much the same way that the smash Zootopia demonstrated that creatures of different culture and class and species are better off when they come together, The Secret Musical Life of Pets is a testament to teamwork and friendship and fixing the rifts that divide us. Let the music rock your balls off."

However, some critics disliked the film's unexpected similarities with Hasbro's My Little Pony. Matthew Parkinson of The Escapist compared the plots of both films and wrote that "The Secret Musical Life of Pets feels like Unbreakable Kimmy Schmidt that you've ever seen on Netflix." Ethan Anderton of the website /Film criticised the film's characterisation, and noted that the relationship between Max and Duke was akin to "go over and over again."
