My dog has a short coat (pit bull) with no insulating undercoat, so she gets cold easily. We went backpacking last weekend and I brought her a fleece blanket to lay on/under, but that wasn't good enough and she was shivering (the low that night was 39*F). I had to let her get in my sleeping bag, which needless to say, kept me from sleeping very well. She gets pretty compact, but is still too big for both of us to fit comfortably into my mummy bag. So I am wondering if anyone has any ideas for a dog sleeping set-up. Obviously I need to get her a pad too, but I think she is going to need some insulation on top... I was envisioning something like a circular (or square) sleeping pad that has a quilted insulated cover attached 3/4 of the way around. I'm not sure this thing exists and may end up as a DIY project (problem is I don't own a sewing machine). Thoughts?
