So my dog is skinny as heck and I'm wondering if you guys had any suggestions for keeping her warm while we are sleeping. She is fine all day when she is running around but I'm guessing she is going to get pretty cold when it gets below 35 this weekend. I'm bringing my tent so I think it might just be warm enough for her in there but I'm wondering if I should bring a blanket or something so she has a layer between her and the ground. Do you guys ever bring anything for the dog other than food?
