I would actually suggest using straw in the shelter or dog house or what have you! Blankets can become freezing cold if even a tiny bit of water gets on it like from rain or snow. But straw repels liquid quite well and so will remain warm and toasty for any animal on it! That is why they use them in feral cat shelters.

Reply to LPT: If you have a stray animal that you want to keep warm this winter, consider using mylar blankets to line their shelter/bedding. They're inexpensive and retain heat extremely well. by Sillylovesongs2
