Beverly Hills Chihuahua 3: Viva La Fiesta!

After their wedding, Rachel and Sam decide to find new jobs. The Langham Hotel is willing to let anybody who can take the place of the landscaper and chef live in the hotel. Sam and Rachel bring Chloe and Papi to the hotel, where Chloe and Papi meet Oscar and Jenny, the hotel's Doggy Day School teachers. Papi is less than thrilled when he discovers he will no longer be teaching the pups. Mr. Hollis, the manager, notices Chloe and asks if she can make appearances as the hotel has gained a major threat, Montague, the owner of the new hotel to rival the Langham. Because of this Sam and Rachel get the jobs. Rosa is also not much happier at the thought of Doggy Day School. Pedro also comes along to the Langham decked out in sunnies. The humans, chihuahuas and Pedro are blown away at their room's luxury. However Rosa isn't feeling happy and is nervous about day school. Papi comforts her, telling her about how he was a chamberlain at a friend's Quinceanera when Pedro finds a picture in a box marked "DO NOT OPEN". Papi tells her what a Quinceanera is about. Later, Chloe, Sam and Rachel start work and the puppies go to school.
