Guide to Buying a Doggie Door

Location – A major factor when considering the purchase of a dog door is where the door will be installed.

Because the dog will most likely stay around the door area, it will also mean the area will have more traffic. You may need to rearrange some furniture or fragile pieces to allow your dog to have room to access the door.

Size – Dogs come in different shapes and sizes and so do dog doors. Don’t assume that doggie doors are a one-size fits all item. Measuring your dogs height, width and weight will ensure a proper fit.

Features – Dog doors these days come with a variety of features from standard to motorized to doors with implantable microchips. Decide what features are important to help narrow down the choices.

Weather – Where you reside plays an important role when purchasing a doggie door. If you live in an area that is prone to harsh weather, such as snow or extreme wind or heat considering a pet door that is tightly sealed and insulated is an option.

Price – Never sacrifice quality for price. Having a doggie door that fits your dog as well as your living area is key to a successful door that your dog will be comfortable using. Comprising valuable features to lower costs is never a good idea.

Also, cost is a determining factor for many large breed dog doors. For those who are frugal, the best dog door is shown in the below video:

Training – Don’t assume your pet will automatically understand how to use a dog door. More likely than not, you will need to train your dog how to use the door. One easy way to do this is to have one person on the inside gently pushing the dog through the door while another person is on the outside with a treat.

Doors for Renters – When renting your home it is imperative that your landlord approves of installing a doggie door. Because a large breed dog door requires the process of cutting a hole in the wall, renters might want to consider a door that can be installed inside a window or glass-sliding door.

Security – An important consideration when having a doggie door is safety and security. To keep out unwanted animals and people, always lock the door at night. Most doors come with locks or sliding covers. There are also electronic doors that can only be opened by your dog.

Child Safety – When having a small child, take into consideration that the child might fit through the door as easily as your pet. Infants and toddlers should never have access to doggie doors. Older children should be advised of the dangers of getting hurt if they try to crawl through the door.

Sea Level Concerns – Those who live in areas that are below sea level need to be particularly cautious when investing in a doggie door for your Great Dane. Areas below sea level are subject to heat, humidity and frequent flooding. Ask a professional which dog door is more suitable for your dog in your particular region.
