We are expecting a litter of Yorkies around December 22nd and I am open for any suggestions on the best way to keep them warm, approximately 80 degrees. I definetely do not want to have the heat on in our entire house at this temp. Are there any particular heaters or special lights that anyone can suggest or recommend? Any suggestions at all for the whelping process I would love to hear, as this is our first litter of Yorkies. We are so exited!
