Best dog door for cold weather

When the sun’s out, and the weather’s warm, leaving the door open to allow your dog the freedom to come and go as they please isn’t an issue, but it’s a different matter when the weather is cold. The door dance will be familiar to anyone with a dog – as soon as you let your dog out they want to come back in, and when they come back in they can’t wait to go out again.

Not only is playing doorman to your dog frustrating, but it makes keeping your home warm in cold weather near impossible. Dog doors give you the best of both worlds; they allow your dog access while keeping the heat in. Our quick picks are the PlexiDor dog door for overall convenience, weatherproofing and durability but if you’re looking for the best door for wall mounting the Endura flap is our top pick.

Best dog doors – How to choose

Dog doors come in all shapes and sizes, as do our dogs. Whether you need to provide access in a wall, wooden door or pane of glass, there’s a dog door suitable.

In this article, we’ll be reviewing the following dog doors for cold climate

But to help you choose, here are a few things to consider;


Perhaps the most crucial consideration in picking a door is where you want to put it. While the most common installation has historically been in a back door, there’s a growing need for doors that fit walls, glass and screen doors. The construction of a pet door varies based on where it’s going, so it’s important to get this right before you invest.

It’s also worth thinking about how convenient your chosen location is. Once your dog gets used to going in and out without your help, they are likely to spend much more time in the area. Furniture, ornaments or other household objects are in danger of getting knocked over. Not only that but bad weather means wet paws, so flooring needs to be dog proof.


The best dog doors for a cold climate have energy-efficient door seals. This ensures that your home stays nice and warm while your dog has the freedom to come and go as they please. If you’re lucky enough to live in a more temperate climate, the door seals are less critical but still something to consider.


The security level of the dog door is especially important if you’ve got a large dog. While there’s not many, who would attempt to access a house that contains a big dog having a locking dog door adds an extra level of security.

Dog doors have different types of locking devices. Some have manual locks others have smart locks, and still others are unlocked by a device that your dog wears. Consider your neighbourhood, ease of access to your house and the size of your dog when considering the security aspect of a dog door. It’s also worth thinking about potential animal intruders, from trash pandas, alligators and neighbourhood cats, locking dog doors keep unwanted visitors out.

Your dog

It may seem obvious, but you need to think about your dog before investing in a dog door. Are they timid or shy, boisterous or bouncy? Do you have an elderly dog with mobility issues or live in a multi-dog household with dogs of different sizes?

Dog doors differ in the amount of effort it takes to open them, the height of the stepover your dog needs to negotiate and the sturdiness of the materials. All of which affects the doors suitability for your dog.

Before you buy a dog door

Once you’ve decided on the best place for your dog door, the next step is to measure your dog. While dog doors don’t need to be the same size as your dog, they do need to be big enough for your dog to use it comfortably.

  • Height; Measure your dog from shoulder to floor. If you have a multi-dog household, measure to the tallest and shortest dogs in your pack. Two inches above shoulder height is ideal.
  • Width; Find the fullest part of your dog, usually around the shoulders or hips. Again, two inches bigger than the widest part of your dog is comfortable.
  • Weigh your dog; heavier dogs need sturdier frames and materials.
  • Growing room; If you’ve got a puppy you need to factor in growing room and estimate the final size of your dog based on breeds statistics.
  • Step-over; this is the height of the pet door from the floor. Some dogs are capable of navigating quite high stepovers, but if you have a dog with limited mobility, it’s a significant consideration

A good way of getting an idea of the size of the door and how it will look in place is to make a mock-up out of cardboard.

Best dog door for cold weather conclusion

There’s no doubt that dog doors are convenient, but don’t expect your dog to use one without some training. Be patient and teach your dog how to push through the door using tasty treats. Timid dogs may take longer than bold dogs to feel comfortable using a dog door, but most get the idea eventually.

Giving your dog the freedom to come and go as they want is a real bonus. But keeping your house warm in a cold climate is even more critical. Your choice of the best dog door for cold weather depends on some essential elements such as the location, size of your dog and in some cases the potential of outside intruders both human and animal. While we’ve provided our top picks – the PlexiDor dog door for overall convenience, weatherproofing and durability and the Endura flap for walls, there are many more available making it almost sure that you’ll find one to suit.
