Last Updated:

Dog doors are a brilliant invention that allows your dog to come and go. Gone are the days when they had to whine and bark to grab someone’s attention to unlock the door! Your dog may now enjoy their free time without having to wait until they’re ready to come back into your life.

When the sun is shining and the weather is nice, keeping the door open to let your dog come and go as they want isn’t a problem; however, it’s a different story when the weather is chilly. Anyone who owns a dog is familiar with the door dance: as soon as you let your dog out, they want to get back in, and as soon as they get back in, they want to go out again. All dogs can get cold, even cold-weather dogs like Labs do get cold in chilly weather, especially at night. Playing doorman to your dog is not only annoying, but it also makes keeping your house warm in the winter nearly hard.

The best cold weather dog doors will provide you with the best of both worlds: access for your dog while keeping the heat in.

What Is The Difference Between Cold Weather Dog Doors And Regular Dog Doors?

Standard doors aren’t always appropriate in all climates. In extreme climates, we require a dog door to keep drafts out and heat in. 

If you live in a colder environment and choose to install a standard dog door, your door will most likely leak heat in addition to not being weather resistant. You need to choose a dog door specifically intended to keep out harsh weather, which will last longer and save you money on maintenance.

The weather seals used in cold weather dog doors are being used in mall and movie theater doors, so you can trust them to perform the job. Doggie doors for cold weather are frequently composed of excellent metal frames that can withstand rain, snow, and wind.

What Are The Types Of Dog Doors For Cold Weather?

  • Wall mount doggy doors are the best for cold weather since they are more durable, fit better, and provide insulation from the wall around the entrance. However, these are more difficult to install, and you may need assistance.
  • For a variety of reasons, electronic doggie doors are the safest. The door will not open to a neighbor’s pet or a rodent such as a raccoon or other obnoxious animals. It only allows the RFID microchip in your dog’s neck to open the door. 
  • Patio panel is the simplest and quickest to put together. All you have to do now is cut a hole in your patio screen and put the door in place. However, these aren’t the best for keeping the cold out.

What To Consider When Choosing The Best Dog Doors For Cold Weather?

Dog doors, like our pets, come in a variety of forms and sizes. There’s a dog door for every situation, whether you need access through a wall, a wooden door, or a pane of glass. 

However, there are a few things to consider to assist you in making your decision:


The location of the door is maybe the most important factor to consider while choosing one. While rear doors have traditionally been the most popular installation, there is a growing need for doors that fit against walls, glass, and screen doors. Because the structure of a pet door differs depending on where you will use it, it’s critical to get it right before investing. 

It’s also essential to consider how accessible your chosen area is. Your dog will likely spend a lot more time in the area once they’ve gotten used to going in and out without your help.


Energy-efficient door seals are the best dog doors for cold weather. It keeps your house warm while giving your dog the flexibility to come and go whenever they choose. If you reside in a more moderate environment, door seals are less important, but they should still be one factor to consider.

Your Dog Size

It may seem self-evident, but you should consider your dog when purchasing a dog door. Are your dogs timid, lively, or boisterous? Do you have an aging dog with mobility limitations, or do you live in a home with multiple dogs of various sizes? 

The amount of effort required to open a dog door, the height of the stepover your dog must negotiate, and the materials used vary. All of these factors have an impact on the pet door’s suitability for your dog.


If you have a large dog, the dog door’s security level is critical. While few people would attempt to enter a home with a large dog, a locking dog door adds an added layer of security. 

Dog doors come with a variety of locking mechanisms. Some feature manual locks, while others have smart locks, and only a gadget worn by your dog can unlock it. When it comes to the security of a dog door, consider your neighborhood, ease of entry to your home, and the size of your dog. Locking dog doors to keep unwelcome visitors out is also a good idea when it comes to potential animal intruders, such as raccoons, alligators, and neighboring cats.

What To Look For When Choosing The Best Dog Doors For Cold Weather?

When choosing the best cold weather dog doors, dig a little deeper into the following details:


Most dog door concerns for cold weather are that they constantly let in drafts and wind. Some people even lock the door when it isn’t in use, but it hinders the benefit of your dog being able to leave and enter your home whenever they want. Your dog door must be entirely waterproof to prevent outside elements from entering.

Single and Double Flap Doors

The single flap door is the most common and, in most situations, performs an excellent job of keeping the cold out. Those with multiple (or triple) flaps, on the other hand, keep out more air. 


Just like any other door, insulation keeps the cold out better than one without it. Your doggie door should also be well-insulated to prevent cold air from penetrating the materials. Make sure you choose correctly because some dog doors have a lot of insulation while others don’t have any at all.


A magnetic strip is the most typical way for these doors to work. We recommend a magnetic seal since it closes up when the door is not in use. It will keep the heat inside while keeping the cold outside.


Some materials like plastic frames shrink in cold climates, whereas they expand in hot weather. A shrinking pet door would almost certainly allow a cold draft into your home, so look for a winter dog door made of the best materials available. Steel is the ideal material for a doggy door, and it should also be insulated to keep the cold away.

Best Dog Doors For Cold Weather

If your dog has to go outside regularly, you may want to give them the ability to do so on their own — but not at the expense of your energy cost. Because of its self-closing and weather-blocking components, the best-insulated dog doors let your pet out while keeping warm or cool air in.

Frequently Asked Questions About Cold Weather Dog Doors

How big of a dog door do I need?

It’s important to choose the right pet door size for your pet’s health and the lifespan of your pet door investment. Review the important factors to consider while selecting the right pet door for your home. The golden rule for dog door dimensions is to choose a size that clears your pet’s back by at least 1.5 inches; ideally, the dog door height should be two inches. When it comes to the bottom, also known as the lower rise, it’s all about providing adequate room for dogs to step over it simply. While we can estimate dog door sizes based on breed, it’s best to measure your dog’s size.

How much will it cost me to install the dog door?

The price of a dog door varies depending on its size and features. The average cost of installing a manual medium-sized wooden dog door measuring 8″ x 15″ ranges from $150 to $600, with most homeowners spending about $300. A modest manual plastic dog door measuring 6″ x 7″ in a door can cost as little as $100 or as much as $1,500 for an extra-large aluminum electric dog door measuring 12″ × 23″ in a wall. It might be worth seeking quotations from local handymen or glaziers.

How do I keep a dog door from freezing shut?

A pet door freezing shut is extremely rare, but it can occur in severe instances when cold and humidity are combined. To provide a barrier between the frame and the door or wall where the pet door is, you may choose to add a foam weather seal to the back of the pet door frame. If the door still doesn’t open, apply hot tape to the edge. 

Wrap Up

Allowing your dog to come and go as they choose is a huge plus. However, keeping your house warm in the winter is much more important especially if your concern is your dog care. You must consider several factors, including your location, your dog’s size, and, in some situations, the possibility of outside invaders, both human and animal, for you to come up with the best cold weather dog doors.
