1. Easy access. Letting your dog come and go with a dog door means you won't have to hassle with getting up to open the door every time he or she wants in or out.
2. Energy efficiency. Opening your door lets out warm air in the winter and cool air in the summer. By letting your dog enter and exit through a much smaller, insulated opening, you won't lose as much of your conditioned air to the outdoors.
3. Fewer accidents. Sometimes you're just not around when your dog needs to go outside. If your dog can manage on its own, you'll have fewer messes to clean.
4. Reduced door damage. Scratching on screens and doors is a good way for dogs to let you know when they want in or out, but this causes a lot of unnecessary wear and tear. No more with a door mounted dog door.
5. Increased independence- for you and your dog. Midday trips home from work to let out the dog can become a nuisance, even costly when you rely on a car. Installing a wall mounted dog door makes it possible to come home as you please, rather than out of necessity.
