Doggie door
From Wikipedia, the free encyclopedia
A doggie door is a hinged flap set into a door, wall or window to allow dogs to enter and exit a house on their own without needing a human to open the door. Doggie doors generally must be bigger than cat flaps and therefore are often constructed differently; except in rural areas they tend to give access to fenced-in yards or gardens rather than the neighborhood at large.
Doggie doors are found to be convenient by many dog owners, because it lets their dogs come and go, as they please, which allows them to put an end to all the trips needed to take their dog outside and avoids other things, such as the dog scratching on doors or walls and excreting on the floor in the house.
Doggie doors are generally designed to be safe for any pet. The flaps are often designed with soft vinyl that does not trap or injure the dogs in anyway. Doggie doors also sometimes consist of permanent magnets to make the door a draft-free, energy efficient closure.
