Air Tight Design

To stop the cold from impact your home, an airtight dog door is a must. The better products take steps to counter the elements but you might need more than a magnet at the bottom of the flap. An insulated dog door can go a long way towards protecting yourself from massive heating bills.

Magnetic Seal

After your dog moves through the door, the flap should stay in place so any breeze doesn’t start flowing through your home. Reliable magnets that are strategically placed can help to counter this.

Ease of Installation

For many dog owners, this will be the most important factor when looking for the best dog door. Some are known for being easier to install tan others so be mindful of the ones that are known for having difficulty to follow instructions.

Different Types of Dog Doors

With a variety of designs, it can be hard to pick the right dog door that suits your home and your needs. Here are some of the most common:

Door Mounted

One of the most popular variants, a door-mounted dog door is made to fit the lower section of a door. Check on the specifics of the product to make sure it is suitable for the thickness and type of door you are looking to use it with.

Sliding Door

Any patio style door or other sliding-type can be turned into a dog door without any difficult installation process. They run the full height of a glass door so it can cost a bit more but they are usually fixed onto the frame without having to make any cuts of alterations and can be taken out just as easily. This makes them well suited to renters who cannot make changes to the building.

Micro Chip

Using smart technology, these operate via a sensor that interacts with your dogs’ microchip or a specialist collar. When your dog is near it will unlock then remain shut so a stray cannot enter. Most products that use this technology offer the ability to program multiple pets.

Wall Mounted

These require the most skill to install but are generally sturdier than a lot of the alternatives. After cutting a hole in the wall, you install the thicker, more durable wall mounted dog door but be wary of getting the correct size as amendments can be tricky.

How Do I Choose The Right Size Dog Door?

This can be a tricky part of choosing the right one for your dog but since most products come in a variety of sizes, you should be able to find the right one in the brand you like.

Most companies give you specific guidelines for measuring the size you need. Measure beyond the neck as the withers between their shoulder blades is about the highest point. Don’t leave it too tight, just choose the next size up if they are measuring too close to the upper limit of one size.
