Title: Keeps out the outside, but difficult for dog to get through
Review: This is well made and helpful that you don't have to "box in" the wall.My dog found it to difficult to push throught the 2 flaps, so I took off the outside flap. I live in Buffalo, and it still seals nicely and keeps out cold and wind. A very small dog will have trouble pushing through both doors, but I still recommend it for it's versatility and quality of manufacture.
