Can a Dog Door Be Too Big? (Solved & Explained!)

No, dog doors can’t be too big but they can be too high off the floor. A dog door that is too large can still be used by your dog. Just don’t install a dog door that is too small. The door itself might still be used, but a door that is too small won’t be rated for a larger dog’s weight and can quickly result in damage to the dog door and the door it is actually housed in.

For the remainder of this article, we’re going to answer the questions which are trending the most this week on the subject of dog door installations. Are they energy efficient? How do you keep the wind or rain outside? Read on to find out the answers to these popular questions and more!

How high should the bottom of a dog door be?

If you have one dog, then the step should be as high as 1/3 of the dog’s overall height. With multiple dogs, go with 1/3 of the smallest dogs height to make sure that everyone can easily come in and out of the dog door whenever they like.

How do you make a dog door smaller?

You can reduce the size of a dog door, but often it’s easier to simply replace the door in question. That said, options for making a dog door smaller include weather stripping, silicone caulk, or simply framing the opening and cutting the plastic flap so that it will work with the new configuration.

This can done quite cheaply but if it’s a hollow door, consider simply replacing it – you’ll have an easier time of it and the new door will be more durable for it.

How tall should my dog door be?

Your dog door will need to be at least 1 inch taller than your tallest dog. This will ensure that they have plenty of room to come in and out and if you aren’t sure about the door size that you need, then just go with a larger door.

A dog can easily use a door that is too large for them, but one that is too small will quickly become damaged from the unsupported weight and the wear and tear of your dog squeezing through the too-small opening.

How big is a large dog door?

Prefabricated doors have fairly standard sizes, with a large dog door measuring in at 10 inches by 19 inches. This is generally a good fit for a large breed such as a German Shepherd, Doberman, or a Bulldog, but if you need something larger then extra-large is also available.

Extra-large dog doors will measure 12 by 2 inches and are a good fit for breeds such as Rottweilers, Sheepdogs, or even Saint Bernards.

How energy efficient are dog doors?

That depends on the specific door design, as well as the materials involved. Some doors come with features like double flaps for added insulation, airtight seals, or automatic locking mechanisms that work by means of a transponder chip in your dog’s collar.

If you are going with a basic dog flap, you can winterize it a bit with weatherstripping and by affixing magnets to the base and a metal strip at the bottom so that the door is held closed when your dog is not using it.

How thick is a dog door flap?

That depends completely on the model that you select, though most standard vinyl dog flaps will only have a thickness of ¼ of an inch. Some of the more popular models, such as dog doors from Endura, have a thicker flap with 1/3 of an inch thickness being standard with their doors.

These are worth considering, as a dog door that is poorly insulated can have a heavy impact on your electric bill, so it’s worth the extra investment.

What size dog door do I need for a Husky?

You should go with a large sized dog door if you have a Husky at home. The measurements will be approximately 11 by 17 inches and this should be a sufficient height and width for the dog to make use of this door even when they are fully grown.

If you are worried because your Husky is a little bigger than most, you can always go with an extra-large doggy door, which measures in at about 12 by 23 inches. Your Husky can easily use the bigger door and you won’t have to worry that they’ll outgrow it.

Is it better to put a dog door in the wall or door?

Installing a dog door in a wall is actually much easier than doing it in a door. It is also a better option if you are working with hollow doors, as one mistake in an install can damage the door frame and require that you purchase a new door to replace it.

Wall doors are also tend to be more durable, especially if you go with an aluminum frame, so they’ll have a bit more permanence to them if you decide to go with this option.

How do I stop wind from blowing in my dog’s door?

If you are using a standard ‘no-tech’ dog flap then your best option is to attach magnets to the base and then install a metal strip for them to stick to.

This will create a rudimentary means of keeping the wind out, although an upgrade to a magnetic lock or a microchip door will seal up the door completely, as it’s locked when not in use.

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

An airtight seal is best and you should also install it so that there is a ‘step’ going into the home which is 1/3 of your smallest dog’s height above the ground. This will keep out any flooding, while the airtight seal will help keep that rainwater outside even with an aggressive local storm.

Finally, consider and electronic model that works with a microchip. These doors stay locked and closed tightly until your dog is nearby, which will minimize the chances of rain coming in more than any other option except perhaps a double-flap configuration.
