Most are well treated. And if you ever see a crew of sled dogs getting hitched up for a trip, they are so excited and happy to be going out on the trail. They are smiling, barking in delight, and some are literally jumping up and down because they can't wait to get going. Yes, it's work, but they live for running with their pack and they absolutely love it. Hopefully, they get a nice retirement after the work is done.
