Here is Jenna Personality from Balto 1, 2, 3: Jenna is kind and sensible, being the only town dog shown who never fawns over Steele and openly stands up to him. She is highly loyal to her owner, Rosy, as evidenced when she stays by her side and does her best to keep watch over her while she is ill with diphtheria. 
Despite Balto's outcast status, Jenna is compassionate to him and is his only friend in town. Her feeling grows closer to Balto as he shown her to also care about Rosy as Rosy didn't view Balto as a threat and later, Jenna would save Balto from being killed from the bear as also getting injured in the process. Jenna gave her bandanna to Balto in hope of keeping him warm and also worrying about Balto going alone. She dislikes Steele for his remarks about Balto and his arrogant attitude, and always sticks up for Balto whenever present, scolding Steele and calling him a "glory hound." Though she is polite otherwise, she continually rebuffs his flirtatious advances and makes no secret of preferring Balto over him. She is far from gullible, as evidenced when she refuses to believe Steele's story about Balto attacking him and dying. So she's jovial, even-tempered, nurturing, nice, astute, jolly, empathetic, noble, no-nonsense and affectionate.
Jenna is also very cunning, as demonstrated when she tricks Steele into burning his tail by using his infatuation of her against him. She is courageous and willing to resort to battle to protect her loved ones, as evidenced in the original movie when she fights a bear to save Balto and his friends. In the sequels, she usually stays behind on Balto's adventures despite wanting to help. Jenna also cared a lot for her puppies but was willing to find them homes after eight weeks.
Here is my comments: I'm getting no hint or proof that Jenna is Gay at all. I don't know how people come up with those things at all. As well Jenna does not love Steele but Loves Balto.
