1) Phil Weinstein has said that Steele, the antagonist from the first movie, was originally set to appear in Balto 3--in this case, Steele would've been one of the volunteers who would help Balto in his search for Duke. While not much else is said about this, this information seems to indicate that Steele may have eventually changed his ways after the events of the first movie. 
2) The primary events of the film take place during the summer, as Stella stated she is spending the summer vacationing in the area. 
3) Unlike the first two movies, Balto 3 doesn't have a true "villain." Duke's probably the closest thing the movie has to an antagonist, but even then, he has heroic intentions. 
4) Ultimately, Duke's just trying to help the people of Alaska and make life a little easier for them by helping to get their mail and stuff faster--it's not like Duke has any idea just how seriously the mail-service dogs (particularly Kodi and his friends) take their job. 
5) Balto Fandom, other people made Balto/Jenna have Incest Sex with Kodi. Forced Sex or not. Kodi being Romance Attracted/Having Sex with Aleu. Aleu was shown off in Balto 2 Wolf Quest. Balto is Dad/Jenna is Mom. Aleu is their daughter and Kodi is their Son. It’s very popular with bisexual, lesbian, straight ideas between all of them. Would rather not knowing this exists. Because I don’t think anyone of them would freely have sex with each other. 
6) Balto Fandom, other people Believe Kodi is Gay. I have covered his Personality being this: Kodi has appeared to display a similar personality to Balto. Kodi has a strong sense of duty and responsibility, but also has his faults (such as allowing Balto to attempt a rescue mission into the Alaskan frontier alone for the sake of keeping his job). He remains fiercely loyal to his friends and his job. Going to such heights such as forsaking his family's wishes to keep them content. He is also laid-back and cool-headed. He has a strong drive and passion for sled racing and wishes to push himself to the limits due to events in his childhood, where he was physically the weakest of the entire litter (presumably the runt of the litter). Shares a strong bond with his father due again to his childhood experiences and is extremely proud to be his son. He's one of "the glass is always half full" type. And what's more, he is kind, optimistic, daring, independent, knowledgeable, outspoken, dependable and intellectual. 
There is no hint of him being gay at all. But someone does have a Post called Kodi from Balto 3 Wings of Change is Gay. Ironically Aleu from Balto 2 Wolf Quest. Balto Fandom, other people are lesbian. Aleu personality being this: Personality is 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. I don’t know how in the heck Balto Fandom thought up about Kodi and Aleu but Would rather not knowing this exists with Pictures and Stories exists. Believe is not ruining my childhood more like ruining the characters. 
7) Mel & Dipsy two characters there are They replaced Dixie and Sylvie. 
8) Steele was originally set to appear in the third as one of the volunteers in Balto's search for Duke—this suggests that Steele may have eventually changed his ways.
9) Dusty uses Aleu's animation model
10) Dusty is the only confirmed female to be a sled dog
11) Lot's of people assumed that Dusty loved Kodi by the reaction she gave when Kodi disbanded from the group. However, they were never planned to be mates in anyway
12) Balto Fandom, other people made Dusty from Balto 3 and Aleu from Balto 2 Lesbian/Shipping Couple. I do know about a Photoshop Picture of Aleu and Dusty Romance love for each other. I don't know how people think up those things. 
I'm done Did you know of Balto Movies.
