Most doggie doors have covers that go over the slot. We put it on whenever we don't want Tucker to go outside or when it is real cold. They have some that have an electronic lock and a special fob thing that goes on your dogs collar. It unlocks the door when your dog approaches and is locked if any other beast tries to enter.Originally Posted By: Toby & LuckyI am considering one in our next home, too, so I'm glad you ask this question!!
They have ones that you can lock when you don't want them to be able to go out, right? Anyone have one? Opinions?
