Thx for all the input. He did sleep in the synthetic with me last trip but he got mad as I would wake him when I rolled as I turn a lot. I had a hard time sleeping with him in the bag needless to say a mummy is tight enough alone. While hiking he didn't seem cold only while stopped at camp. I'm looking into the ruff wear dog jackets but they are a little pricey. I'm going to cut a small section off my zlite sol sleep pad for a pad for him and thought an old down vest would be cheap and could sew arms and bottom shut to keep warmer. The quilt idea is good but would prob be more $$. Where can I get a small quilt? He weighs around 15lbs. If I were a gram weenie I could let him sleep in my jacket but prefer not to smell like a dog
although he prob smells better than a hiker!! Thanks again for the input..
