Of the six puppies Balto and Jenna had, only three of them have official names (the credits confirm this), which are Aleu, Dingo and Saba. Any other names you may see are unofficial fan names. 

Saba is light red with blue eyes, however sometimes, due to inconsistencies, her eyes are brown. She is the puppy who asked Balto if he's going to get a human too, and is the third to the last puppy (the Aleu clone was adopted at the same time she was) to be adopted.
