I'm so glad you watched this movie and enjoyed it. I love it. It's so good and so few people have ever even heard of it. Fun fact: The main dog who played Togo in the movie is a descendant of the real dog.
As already mentioned, you should check out also the movie Eight Below, about 8 sled dogs surviving in Antarctica for 6 months and the attempt of their human (guide) to rescue them, played by Paul Walker - RIP. The movie script is loosely inspired by a real story from 1958. The real story was more cruel, but the movie being Disney's, was made more family friendly. Still a nice movie and also a tearjerker, so be ready if you decide to watch.
My youngest and I watched this and we knew the story of Balto but never knew about Togo. So good history lesson there. In history, as a child, I got a brief blurb in the book about Balto but that was it.😊
