One night when it was around 15 f I was trying to get my dog to come in the house because I didn't want him to spend the night out side.He would not come in so I went out side in just my boxers and it was cold. I found him in his dogloo so I climbed in to get him out and I found out that it was very warm inside. Of course I had already put some hay inside. I believe that they will keep your dog warm at least until 10 or less. I also had put a thin plastic strap door so his body heat would stay inside the dogloo.
