Why Buy An Endura Flap?
Considering your dog is going to open the dog door with their face, you owe it to your pet to choose a doggy door that has a flexible flap. The problem with flexible flaps is that they shrink when they get cold. This unfortunately means that when it's coldest and you need your dog door to seal its best, it will actually seal its worse. What? Really?? Sad but true for most flexible flaps, but this is what separates the Endura Flap® from the rest.
