Do Doggie Doors Let Cold Air In? (Solved & Explained!)

Yes, doggie doors can let in cold air in the winter. This makes investing in autolocking electronic doors a good idea but you do have other options. Insulating an existing dog flap and adding an airtight seal or at least a flap with magnets or bellows can help to reduce the weather’s impact on your bills.

In this article, we’re going to answer popular questions about dog door energy efficiency, weatherproofing, and their potential to affect your insurance. Read on to see what questions are trending this week about doggie doors!

How do I keep cold air from coming in my dog’s door?

Winterizing your dog door is a good idea for keeping out drafts and ensuring that your heater bill isn’t overly affected by it’s use.

Weatherstripping can help to seal up cracks and if you have a ‘flap’ model that doesn’t lock into place, you can superglue magnets to the base along with a metal strip underneath to produce a makeshift seal. Silicone caulk is also good for cracks and with a wall door, adding a second flap can greatly reduce those drafts.

How energy efficient are dog doors?

It really depends on the model that you choose. For instance, a microchip dog door can lock and unlock as the door is used, providing a locked barrier to keep out the drafts when it’s not. Some ‘flap’ models incorporate an airtight seal, tight enough to keep out a draft but not so tight that your dog can’t use it.

Be sure to ask about weatherproofing features before you settle on a purchase – it can make a big difference on heating and cooling costs and it won’t cost you a whole lot extra to get that protection.

Do dog doors let in heat?

If you are using a flap model that doesn’t come with an airtight seal, then you can definitely end up affecting your heating or cooling bills. Without a seal, heat will definitely get inside during the summer, and winter drafts will also be a problem.

Go with an electronic model that seals the door when it’s not being used or consider insulating the entrance a little more with silicone caulk and magnets to hold the door closed to help reduce the hit to your electric bill.

How do I stop my dogs door flap from blowing open?

The easiest way to stop a door from blowing open is the addition of magnets. These can provide a rudimentary seal, just keep in mind that this is still a poorly-insulated option – it might well be worthwhile to upgrade to an electronic model or at least a spring-hinged door with an airtight seal.

Do magnetic dog doors let in cold air?

This depends on the type of magnetic door. There are models that employ a magnetic key placed in a dog’s collar which open and close based on the proximity of that key. Those models are quite good at keeping out the cold air as they only open when your dog needs to use them.

Other magnetic models simply employ a magnetic seal and the efficacy of these will depend on the number of and the strength of the magnets which they employ.

Do Microchip dog doors let in cold weather?

Microchip dog doors will let in some cold when they are being used, but this will be minimal. As the doors will lock once again after your dog gets inside, the window of cold exposure will be brief.

By contrast, a magnetically sealed flap or a standard dog flap with no seal will definitely let in a lot of cold and this, in turn, will affect your heating bill.

How do I stop rain from coming in my dog’s door?

You want to look for flaps that have magnetic seals or which employ bellows to create more of an airtight seal.

This will help to keep out the rain, but you also want to ensure that the ‘step’ into the dog door is the proper height. It should be 1/3 of your smallest dog’s height to keep it above ground. Without a step, then any flooding can come in through the dog door, so this detail is crucial!

What is the most energy efficient dog door?

There are a number of efficient models, but two of the most highly rated dog doors would be the RuffWeather door from Ideal Pet products and the Endura Flap, which is a product of Patio Pacific.

These models are specifically designed to keep the bad weather outside where it belongs and if the reviews are to be believed, then these models definitely deliver this.

Are doggie doors weatherproof?

Standard dog flap doors are typically pretty basic, so you need to look for models that specifically tout weatherproof features. Look for airtight seals, double flap models, and insulated dog doors.

While these additional features will cost a little more, you will make up the difference many times over when it comes to your electric bill – it’s definitely worth the investment.

How can I make my dog door more secure?

Aside from weather, you want to keep people out of your dog door too. Burglars can and do take advantage of dog doors, reaching in to unlock the door or even poking poles inside to see what they can fish out.

Invest in additional security such as motion sensors, security cameras, or you can even install a security alarm in your actual dog door for when you and your dog aren’t home. This will help to minimize the security risk while still giving your dog their freedom.

Will a dog door affect my insurance?

Dog doors can indeed affect your insurance, though most likely it will only be a change in premiums rather than a change which may void it. That said, be sure to check with your home insurance provider to find out exactly how a dog door will affect your policy before you install it.

In most cases, the impact should be minimal or might be nothing at all – but with insurance you always want to check!
