What is the theme of TC Boyle's Balto?

On the movie Balto was a stray wolf-dog. Jenna, a Husky, Boris, a goose and Muc and Luc two polar bears were Balto's friends. Jenna's owner, a little girl named Rosy and some other kids got sick. Steele, a Husky did not like Balto because he was part wolf. Steele and his team of sled dogs had to go bring back medicine for the sick kids. But when Steele and his team was coming back with the medicine they got lost. Balto went to go find the lost team. He found them, but Steele would not let him take the medicine. Steele and Balto fought and Steele fell off a cliff. Balto and the rest of the team started to go back to Nome. But Steel got back before them and told Jenna that Balto was dead, but Jenna did not believe him. Then Balto came back and the dogs that did like Steele did not like him him cause he lied to them. The doctor gave Rosy the medicine and she got better.

There are two other Baltos, Balto 2: Wolf Quest and Balto 3: Wings of Change.

Balto is one of my favorite movies, you should watch it.
