In the middle of deciding that my girls probably didn't need supplemental heat here in Dallas, I discovered the neighbor's dog is exceedingly pregnant. She lives a life of somewhat benign neglect, and I got permission from him to make a temp dog house for her before she has her pups. I had been investigating panel heaters, and my copy of Backyard Poultry had an ad for Sweeter Heaters. I talked to the owner and he said a lot of dog breeders use them. He also mentioned that they are far superior to the panel heaters you see advertised in other places. Anyone ever get one? I told him I was going to buy one and review it for us here, but thought I would check with others, first.
