1) Aleu's Name was inspired from Aleut Archipelago, off the coast of Alaska. 
2) In the cover, Aleu has a upward tail like her mom but it was entirely downward (like her dad) in the rest of the movie. 
3) Aleu has also made a cameo appearance as a pup during Balto's flashback in the song “You don't have to be a hero” during Balto III: Wings of Change. 
4) Critics didn't liked her voice as much. Some of them criticized her voice as being annoying, whiny, made her sound like a kid despite being almost an adult. 
5) According to various reviewers, Aleu is considered to be the worst character in the Balto universe. 
6) Aleu and her sibling are the only pups that take more features from their father. 
7) She's the only who has blue eyes despite none of her parents supporting any blue eyes but she also doesn't have her sclera's Yellow like her father. 
8) In the sequel Dusty's uses Aleu's animation model. 
9) Aleu and Kodi are the only pups that have a movie dedicated to them. 
10) Balto Fandom, other people Believe Aleu is Lesbian. I have covered her Personality being this: She's very stubborn and brave, prone to not listening to her father. She was also disdainful of her wolf blood (though she eventually learns to accept it). She also dislikes anyone else using improper grammar especially double negatives. Although she never realized it, Aleu acted more like a wolf than a dog. She had a reputation for being aggressive and had a high prey drive and stronger predatory instincts than a common dog. It is unknown how she developed her prey drive as neither Balto nor Jenna possessed a prey drive.  Despite a very emotional blow at the hands of her father, the two reconcile at the end of her journey and she remains very closely tied to Balto despite leaving him perhaps forever. Although there is a chance they may meet again someday.  As a pup, Aleu is highly attracted to howling. In her own words, "Sometimes I just can't help myself," Aleu is strong in spirit and leadership, with all the traits a wolf pack could hope for, she is closely bonded with her father. And she is also known as affectionate, lovable, even-tempered, understanding, athletic, level-headed, empathetic and upbeat. Though she would never admit it, she loves her father very much though sometimes they can get on each other's nerves. Aleu is very outgoing with a tendency to do things without thinking. 
There is no Hint or Proof of her being Lesbian. Sometimes I don't know where people get the ideas-es. 
11) Balto Fandom, other people made up the ideas Steele from Balto is Romance Attracted/Having Sex with Aleu. The Counterpart ideas Steele from Balto is Romance Attracted/Having Sex with Kodi. I have always pictured it's almost like Trevor Phillips from GTA 5 being that way toward Micheal De Santa Kids that are: Jimmy De Santa (Son)/Tracey De Santa (Daughter). The Forced Sex ideas from Fan-made Comic from Balto Family Secret over Steele Forced Sex Aleu and Kodi: Dude That's Creepy 
Sometimes I don't want to remember that stuff. 
12) Pictures and Stories of Aleu from Balto 2 Wolf Quest Incest Sex with Balto her Father, Jenna her Mom, Kodi her brother. The Most Infamous One is a Fan-made comic called Balto Family Secret. As I say before I have a secret think Balto Family would not do that. Sometimes I really need Neuralyzer from Men in Black to erase my memory from Balto Fandom, other people ideas-es.
