I would like to bring my dog with me on my thru-hike come 2007. She is a chihuahua and only 3.5 pounds. Am i crazy for wanting to bring her with me? She hikes with me on a daily basis, but only about 6 or 7 miles a morning. Would the weather changes be too much for her? Any suggestions on really good dog coats that wil fit her if she was to come? Any suggestions would be great. thanks
