The Best Dog Doors for Cold Weather

Not all dog doors are made equal! When thinking about buying a pet door, you’ll need to consider your yearly climate! If you experience harsh winters, you’ll want the most insulating, energy efficient dog door possible. 

What is different about Cold Weather Dog Doors?

Before even thinking about what the best dog door for extreme weather could be, the question has to be asked: what is so special about them? The very best cold weather dog doors will not only keep drafts out and heat in, but will also save you money in the long run. The less heat that escapes through the pet door, the more money you save on heating!

Magnetic Seal
These days, every dog door flap has a set of magnets embedded at the bottom. But maximum energy efficiency requires even stronger magnetic seal. The more magnets, the stronger the seal, and the less likely for the flap to let in cold air.

Low Temperature Tolerant Materials
A heavy duty, insulated flap protects your home from the elements. A lot of engineering can go into the material and design of a pet door. Most vinyl material will flex and shrink in the cold. The design of cold weather pet door flaps should counteract this!

Wind and Draft Resistant
If you think about it, a pet door is a hole right there in your door or wall! And if you’ve ever owned a pet door, you know that they can be the ultimate source of drafts in your home! The best pet doors for cold weather will be able to resist the strong winds and keep drafts out of the house!

Single and Double Flap
Double the flaps, double the insulation for extreme weather energy efficiency! Cold weather pet doors will sometimes have a double flap option. Double flap dog doors help conserve the heat inside and keep out drafts, making them the perfect pet door option for harsh climates.

What are the Best Dog Doors for Cold Weather?

As we said above, the features of the best dog doors for cold weather are their strong magnetic seals, the ability to keep out strong winds, and high tolerance against extreme temperature. With these in mind, here are the best dog doors for winter climates:

1. The Endura Flap

The best dog door for cold weather is the Endura Flap.
Separating it from the rest of the competition, the Endura Flap uses a polyolefin-based polymer flap system that doesn't fade, warp or crack the way standard vinyl flaps can. It can withstand cold climates as low as -40 degrees Fahrenheit and still stay flexible!

The intense magnet strength of the Endura Flap means that the door will stay closed during high winds. In a wind tunnel experiment, the flap stayed shut against winds up to 40 mph! Endura offers a variety of installation options from wall entry doors to sliding door inserts. The high-quality Endura Thermo Panel 3e pops into patio door tracks in a matter of minutes, so it's a convenient option for renters. The sturdy aluminum frame is airtight for maximum insulation. All installation styles include a sturdy locking cover for security.  

On top of the great numbers, the Endura Flap comes with a 15-year warranty and has a double flap option for maximum insulation in the harshest climates. 

2. The Hale Double Flap

The next best is the Hale Double Flap.
With several magnets that keep the dual flaps closed and a fuzzy nylon weather stripping lining the edges of the flap, the Hale double flap offers great insulation for the value. Hale doors have the added benefits of a crystal clear and lighter-weight flap material to accommodate two pets of drastically different sizes (also good if your pooch is a little shy about pushing through a heavier flap). Your Great Dane and Dachshund can both use the same pet door! The wide range of flap sizes makes Hale a great choice if you are looking for a large dog door.

Hale offers custom door mounts and custom wall mounts that can fit to existing cut outs, allowing for ultimate flexibility based on your pet and home needs. The wall mount has a waterproof aluminum telescoping tunnel to avoid any water damage to the interior of your wall. Hale doors come with a 5-year warranty. 

3. The Ideal Draft Stopper

The Ideal Draft Stopper Dog Door seals well at a great price.
With 8 magnets and a three-panel flap design, the Draft Stopper keeps winds up to 35 mph out of your home while still staying flexible for pets. The flap itself is made of hard polycarbonate, but has hinges in between to allow a swinging motion when your pet comes and goes. The Draft Stopper only comes in two sizes and doesn’t offer as much flexibility with installation as the other doors on this list, having no wall-kit or extra large sizes. Make sure to double check the size of your pet when considering any pet door!

4. The Ideal Ruff Weather

The Ideal Designer Series Ruff Weather Dog Door is an affordable option.
Also featuring a double flap, the Ruff Weather door provides improved insulation while still being lightweight for pets of all sizes to use. With weather stripping on the plastic frame, the door is great for keeping drafts out of the house and comes at a modest price. The Ruff Weather, unlike the Draft Stopper, has a small size and two larger sizes that allow for more options for extra small or extra large pets.

Other Considerations

Remember that there are lots of other things to consider when buying a pet door! You can meet all of your needs and still get a winter proof dog door!

Size is super important to keep in mind. Be sure to measure your pet correctly and pick the right door for your pet! Have a small dog or cat that likes to play in the snow? No problem! Take a look at your through wallsthrough windows, and even through a sliding glass door!

Whichever door is right for you, remember that every climate, every home, and every pet is different, so every pet door situation is different. Choose the right pet door for you!

  • Hi Pauletta!

    We typically recommend that the stepover height (bottom of the pet door opening) is no more than 1/3 of the pet’s height (in your case, 5"), and that the top of the flap opening is at least 1" taller than your pet. The Medium Endura Flap wall mount is 14" for the double flap option and 15" for the single flap option. If you mount the pet door so that the bottom of the pet door frame meets the floor, the opening will be about 3" off the ground and 17" to 18" tall.

    Please contact us at with any further questions!

  • I have Skye Terriers and is difficult for me to choose a size of door that will work for them. They are twice as long as they are tall , though they only weigh 28 lbs. They are 15 inches tall and 31 inches long . I was leaning toward a medium. But I didn’t want them to be afraid, It will be installed in a wall. Any suggestions would be greatly appreciated—new construction ..Thank you

  • Hi there!

    We’re so glad you love your pet door! We definitely understand that some dogs (like Benny!) need the taller sizes, and don’t necessarily fit in standard doggie doors. That’s why we offer custom dog doors! When you’re ready for a taller door, feel free to send us an email at We would be happy to help you find something tall enough for Benny! We love talking dog doors!

  • Hi Shereen!

    It can be difficult to give you the best advice without more information, and we want to make sure you get the right replacement parts on the first try! Sometimes you don’t need an entirely new flap, it depends on the situation. Please send us an email at and include a picture or two of your flap (preferably showing the issue, if possible). With a picture, we can help identify exactly what you need so you don’t waste money on more replacement parts. We look forward to hearing from you!

    Happy new year!

  • Hi Robert,

    Good question! In short, yes! Though a few details may be helpful in selecting the right door for your home. The Endura flap is the most insulating dog door, so it’s really the best for those “cold colds” and “hot hots.” If you’re located somewhere with more extreme temperatures, the Endura Flap will save you money on heating and cooling your home. The Endura gets it’s insulating power from the thick material and dual-walled nature of the flap, but also with a tight seal. So if your cat is more timid, or has never used a cat door before, your cat may have a little trouble at first (and need some training). You can easily train your cat by propping the flap open for a while if necessary, or removing magnets temporarily to make it easier to push through.

    Other than the Endura Flap, these other doors listed will also work for your cat. They do not have the insulation value of the Endura, but if you’re not overly concerned about keeping heat or cold air in your home and more extreme elements out, then these doors can be a good alternative. The Hale and Ideal Ruff Weather both come in pretty small sizes, while the Ideal Draft Stopper comes in sizes a little bigger. In the end, it’s all down to your situation and your preference!

    Let us know if we can be of any help, we love talking pet doors!

  • We bought your tallest door with double flaps for our greyhound “Benny”. Love the door and it’s insulating properties. I just wish you made a little taller door. We live in Oregon and the wind dies not effect the door.

  • We need to replace our Endurance Flap Door extra large single flap. On a very windy day this flap will push open. Do we need a new magnet as well?
    Thanks for your help.
