Ah heck.....truth be known .....Hey MM, shall we tell them how we really keep warm here at night and in winter????
While I wait for you to reply, I'll tell them anyways......
Okay, usually on cool/cold nights, we heat large rocks in our fireplaces, or over the fire, get them really hot then place them into the ends (foot end) of our beds.....
But on really, really cold winter nights, we just invite our sled dogs indoors. And like wheeler said, we use them as/for warmth. Only up here we can have as much as an eight dog night, as most dog sleighs can have up to eight pulling them. Occassionally the females have just had a litter and then the puppies can curl up next to our kiddies.
