Thanks for the input all
I will say that reptile hot rock I have works very well on a wool blanket, seems like the wool traps the heat around the rock and the dog curls up around it.
I just ordered a fairly inexpensive ($50) electric kennel heating pad, oughtta do the trick, and that thermocouple doohickee is way cool, just wish they had one turn on and off at 45 or 50F.
Sadly, the days look numbered for this little dog. This past couple of weeks her back legs have been locking up standing straight out and forward like stilts, as if she were sitting down. She pulls herself up on 'em with her front legs and once in a standing position they work fairly well.
Pretty sure this is her last winter.
