TURBRO Neighborhood Dog House Heater

I chose this heater because it actually blows hot air versus a mat or other heater that uses ambient temperature. We have cold winters and 2 indoor/outdoor dogs who are not acclimated to stay outdoors 100% of the time. So I wanted them to have the option for a warm place if they so choose. It has 2 temperature options which I like so it can be used with varying outdoor temperatures. It does not have an auto feature but I believe you can buy a separate non-affiliated accessory that will kick it on once the outside temperature reaches a certain degree. It was very easy to install. During the winter, I covered the dog house and door with a thermal blanket. Occasionally, I would reach in to see how it compared to the outdoor temperature and it was very warm! Definitely warm enough for doggies with fur. We had no issues running it for days at a time. I would highly recommend.
