A dog door is a small swinging door that, once installed in a wall, will let your dog access to the outside of the house. This allows you to enjoy your meal, or your favorite movie, without being interrupted because your dog is adamant on having a stroll in the backyard. With a dog door, your dog has the freedom to move in an out of the house without someones aid.

There are many different types of dog doors, from the basic models that make use of a mechanical flap to the luxury ones that are radio wave controlledThe most common type consists of a single flap or door with a hinge at the top. The flap swings freely when pushed and falls back into place once the dog has passed through. Dog doors also have a lock mechanism, which comes handy when you want to restrict your dog outdoors.

Though quite helpful, conventional dog doors can be a nuisance at times, since stray dogs, raccoons and other similar animals might enter your house. Radio wave operated luxury dog doors can successfully counter this situation. A small battery-operated transmitter on your dogs collar disallows the lock when your dog approaches the door. The dog door otherwise remains closed at all times, thereby warding off other animals.

Dog doors come in a variety of sizes to accommodate different size pets. Having chosen the style, you must ensure that the dog door is large enough to let an easy path for your dog. Certainly, you would not want your dog to get stuck in the door while going outside. Your dog should be able to tread through easily by just lowering its head to force the door open.

Most dog doors are rather inexpensive. However, the electronic ones and those that are fitted in sliding glass doors may incur a higher cost. But cost should not be a major determining factor while selecting a dog door. A durable and automated dog door, though more costly, will take care of the need for constant monitoring of your dog.
