I thought this show was very interesting. All about the important role that dogs have played in Alaska's history. They covered mushing, of course, but also search & rescue and Karelian bear dogs.
The bear dog segment was fascinating. I really didn't know anything about this breed, and holy cow, DO NOT WANT. There was someone's home video of his two Karelians chasing a grizzly, and that bear was hauling tail to get away from these dogs. That is some kind of intensity!
Good show. :)
