Best Dog Doors: Buyers Guide

Finding the right dog door for you and your pet can make both of your lives better. There are a surprising number of factors to consider when picking the best product for you. Since these doors are not cheap and often require you making permanent changes to your home, it is important to get the right product for your needs. This guide is designed to go over the most important considerations to keep in mind when shopping for the best dog door.

The Size of Your Dog

It seems pretty obvious, but the door you buy must be big enough for your dog to get through. Dog doors sizes vary to correspond with your dog’s size. If your dog is not yet full-grown, you must look ahead to the size they will become. You will need to measure both the height and width of your furry friend. Generally speaking, measuring your dog from their paws to their shoulders and then adding 2 inches will ensure the door is tall enough. Width should also be taken at the shoulders. You will want to add 2 more inches here as well.

If you have more than one dog, take the measurements of the largest one to accommodate for all.

The Size of Your Door (or Wall)

You will need to spend some time getting to know the door or wall you are planning on installing your dog’s new entrance and exit on. Pay attention to the material it is made of, such as timber, steel, aluminium or sliding glass. The thickness of the door or wall is particularly important. Many doors are made for thicknesses of 1.25 inches to 2 inches. They also sell telescoping doors and/or extension kits.

If you are planning on using your new product in a sliding-glass door, you will also need to know the height of it. Sliding doors are usually pretty standard and fall into one of two heights. As long as you know what you are looking for, you can find a dog door that will work with your home.

Construction and Durability

The two main pieces of a dog door are the flap and the frame. You will want both of them made of high-quality durable materials. The flap can either be clear or tinted. It needs to walk the fine line of being strong enough to keep the weather out but not too tough for your dog to open. The flap should be flexible. Vinyl is a popular choice for the flap.

Aluminum is the most common material for the frame. This is because it is a sturdy material that will not rust. Plastic frames are on the market and are usually cheaper. That being said, they are unlikely to last nearly as long as an aluminum one.

Locking and Weatherproofing

Many dog doors come with an optional slide-in to control your dog’s access. They are also handy to put in at night or when you won’t be home to keep other animals and the bugs out.

Cutting a hole in your wall or door can make your home less energy-efficient if you aren’t careful. You will want a dog door that has weather stripping to help maintain your home’s insulation. Look out for doors made of aluminium or plastic as these have weather stripping properties. Another option to help with insulation is buying a dog door with two flaps. The air present between them can help insulate your home. The slide-in is yet another option for keeping the warm air in or the cold air out.

The best dog door should be resistant to UV-radiation and extreme weather.

Sliding Glass Door Panels

If you do not want to make permanent changes to your home, or if you are a renter, a sliding glass door panel can be the answer. They simply sit in the track of the sliding door. As a result, they are super easy to both install and remove.

Those who go with this option want to find a door panel that will fit tightly and has weather stripping. You also should look for tempered glass. If you have the option of using a sliding glass door, it may be the easiest option for you. As a bonus, they look pretty neat!

Wall Dog Doors

Dog doors for walls are a popular choice when the wall is the only option for installing a dog door. One of the biggest benefits of this is you can place the door wherever you would like. A second benefit is that replacing the bricks after removal for installation is much easier. They are also made of robust and high-quality insulation materials.

If you want a ramp to your dog door, putting it in the wall is usually the only option. Doorways designed for humans are either ground level or have stairs that will block the way for the ramp. Wall dog doors can also limit dogs to other areas of the home, too.

Unless you have a background in construction, there is a good chance you will need a wall dog door put in by a professional.
