The PetSafe Extreme Weather Dog Door may not be suitable for every home, but it’s definitely one of the best options if you live in a region with an extreme climate. I live in Maine, and our winters are tough. This door has kept the snow, wind and rain out of our home.
"I have four dogs ranging in size from a 75-pound Labrador to a 25-pound Beagle mix. When you’re choosing the right dog door for your pets, you’ll need to select a size that is best for your largest dog. The smaller pets will be able to fit through a larger door, but it wouldn’t work if it were the other way around."
