I have always hiked with a dog. I hate leaving them home when I hike anywhere. On principle it just seems wrong. The issue I am debating is that I have Doberman. He is fairly athletic, and we run and hike whenever we can. But we avoid winter for a reason. I worry I will be miserable when I do hike the A.T. if he isn't with me but I also worry that he will be miserable because I can't keep him warm enough. Any thoughts?
