Beverly Hills Chihuahua 2 (2011): This film focuses on Chloe giving birth to a litter of puppies. While the movie doesn't explicitly name them, we see Chloe with five puppies:
* One brown and white puppy (male)
* One white puppy (female)
* One tan puppy (female)
* Two brown puppies (one male and one female)
Beverly Hills Chihuahua 3: Viva La Fiesta! (2012): This film doesn't focus on puppies but rather on Chloe and her friends going on a trip to Mexico.
Therefore, there aren't any official names for the puppies in either sequel. However, you can certainly give them names inspired by the movie or choose your own!
