Doggie door that actually seals

Hi. We got our dog door. All I can say is just how much we love it. The other dog door made so much noise every time the dogs went in and out. Also, the area around the old dog door was really cold in the winter. I can only imagine how much heating and cooling we lost with the old door. I really wish I had found your dog door before I purchased what I was told was a dog door that sealed. The only thing that was a draw back but not really was the size of the door. It really was bigger than 11 by 17. We are fine with that just had to enlarge our opening a bit. Just want to tell you again how happy we found your website and found that door. Love, love, love it! Thank-you for getting it here so fast.
