What is a dog door? A simple explanation of dog doors!
2. April 2024A dog flap is an opening in a door that allows a dog to leave and enter the house whenever it wants. The same concept also exists as a cat flap. Dog flaps come in different sizes and can be installed in various types of doors. They are usually made of either plastic or aluminum and are kept closed with magnets as long as the dog is not using them, preventing drafts, rain, or heat from entering the interior.
The larger the dog flap, the higher the potential risk of burglary. This is because through a very large dog flap, through which a large dog can pass, a burglar can often also pass, allowing them to avoid the effort of breaking in.

Mechanical and electronic dog flaps
There are mechanical and electronic dog flaps. Both types can be deactivated so that they can no longer be opened when desired. However, the major disadvantage of a purely mechanical dog flap is that—even if it is quite small and a person cannot pass through it—uninvited guests can still enter: other dogs or even cats.
The situation is different with dog flaps equipped with a chip or sensor, as these react to a chip that the dog receives from the veterinarian or to a sensor attached to its body. The dog flap can only be used when the electronics recognize the correct chip or sensor. The sensor is usually sold together with the dog flap and attached to the animal’s collar.
The major problem with a collar-mounted sensor is that a dog can lose it—this unfortunately happens when a dog plays roughly—and then the dog flap is no longer usable. In such cases, you need sufficient replacement sensors or must repeatedly request replacements from the manufacturer.
A dog flap can be activated and deactivated. A deactivated dog flap can no longer be used by the dog because it remains closed. In terms of burglary protection, it is important to remember to deactivate the dog flap at least at night every day, and of course also whenever you are away from home for a longer period.
