Our Economy Dog Door features the patented double flap.

Wouldn't it be great if your dog could open doors? He could go in and out-doors when he pleases (unless you don't want him to, in which case you can close the pet door with the closing panel). If you have to be away from the house for many hours, your pet can now have access to the yard when he wants. The unique flap system will keep it weather tight. Now your pet can come and go as he pleases.

Freedom and convenience for you and for your dog.
