Dog ownership can be quite a bit of work – plenty of folks would say it’s just a step or two below human parenting!

For fur parents, it’s always nice to find helpful hacks that make it easier to take care of your pup. One great way to accomplish this is by installing a pet door.

Pet doors alleviate the need for you to stop what you are doing to let your dog out when nature calls. You can rest comfortably, knowing that she can come back inside without any help, once she’s ready.

Additionally, this provides your dog with the chance to stretch her legs or keep tabs on the local squirrel population (they’re clearly up to no good), when she wishes.

Basic Dog Door Styles

Pet doors come in a few different styles, each of which is best suited for different situations, owners and dogs. The most common styles include:

Door-Mounted Pet Door – The most commonly used pet doors are designed to be mounted in the lower portion of a standard door. These are what most people envision when they hear the phrase “pet door.” Different models work best with different types of doors, so be sure to review the manufacturer’s recommendations before making your selection.

Wall-Mounted Pet Door – Wall-mounted pet doors are designed to be installed into a hole cut into a wall, rather than a door. These are typically thicker/deeper than door-mounted models, rather than a relatively thin door. Nevertheless, they are difficult to install, and you’ll need the requisite skills and tools for the task before selecting this style pet door.

Electronic Dog Doors – Electronic dog doors vary widely. Some open and close automatically, while others are passive units, designed to restrict access through programming options, or when they are triggered by a small RFID chip attached to your dog’s collar. Electronic doors are typically designed to be installed in standard home doors, rather than walls or glass doors.

Sliding Door Dog Doors – Some doggie doors are designed to fit into the gap created by a partially opened sliding glass door. These designs are often easy to install, but because they include a full-length section of the glass door, they are also somewhat more expensive than many door-mounted units. They’ll also make your existing sliding door inoperable for humans.

Your home’s layout and family’s lifestyle are the most important factors to consider when choosing the style that will work best for you. Most of the styles available will work for most dogs, provided that they are available in the proper sizes.

Important Features to Consider When Choosing a Dog Door

After deciding which doggie door style will work best for your home, you can move on to additional considerations, which will inform your ultimate choice. These include things like the materials used in the construction and the ease with which they can be installed.


Dog doors and frames are made of varying materials, although most are made from aluminum or some type of plastic.

Aluminum products are generally more likely to last longer, although premium plastics are often adequately strong – particularly when used in the production of small pet doors.

Installation Difficulty

Some dog doors are easier to install than others are. Some can be installed in a few minutes with no tools or any skills to speak of, while other require copious amounts of both.

In the case of door- or wall-mounted units, you will have to cut a hole through the door or wall, and then assemble the door and affix it appropriately.

For many owners, a professional will need to be hired for the installation (if this is your first time cutting a hole in your house, we wouldn’t recommend having at it alone)!

On the other hand, sliding-door-mounted pet doors are relatively quick and easy to install, and few tools (if any) are needed for the process.


It is important to remember that your dog door will serve as a way for the air in your home to intermingle with the external environment.

Even when the door is in the closed position, a thin piece of aluminum or plastic will not insulate your home as well as a door or wall will. This is especially important for owners living in extremely warm or cold climates.

Some pet doors try to make up for this fact by including two or three doors or flaps, rather than a single one. This helps to trap air inside the door cavity, which will insulate the door.

Still, if energy efficiency is important to you, it’s worth considering how a dog door will affect the heating or cooling of your home.


Pet doors do provide an additional entryway into your home, so you’ll also want to consider the security implications when selecting a design.

Most high-quality units feature some type of locking mechanism, which prevents criminals or unauthorized animals from entering the house. However, you can only engage the lock when your pet is safely inside, which decreases the value of the door in the first place, since the key benefit is consistent in-and-out access for your dog.

One way manufacturers have tried to address this problem is through the use of smart doors, that read a microchip on your dog’s collar. Such doors only allow your pet to enter, while keeping out the neighborhood riff raff.

Additionally, some such units are programmable, enabling you to deny your pet entry or exit at some times, while allowing them to travel freely at others.

The following doors are some of the best options for dog owners:

Doggie Door Alternatives & Potty Solutions

If you’re considering installing a doggie door, it’s likely because you want to give your dog free access to the backyard. We think this setup makes for one happy pooch.

However, if you are starting to feel like installing a dog door is too big of a job, consider these ideas too:

Dog Doorbells. Dog doorbells are strings of bells that are hooked to your doorknob, allowing your dog to hit the bell to let you know he wants to go out.

While you’ll have to train your pooch to use the bells (and heads up, some dogs decide that the bells work great as an instant attention-getting tool), they can be great for ensuring your dog gets let out when he needs to do his business. Of course, someone still needs to be home to let him out!

Grass Potty Pads. Potty pads are a nice solution when you want to give your dog a bathroom option, but he can’t be trusted to hold it on all day. Grass potty pads tend to be especially effective, as they use real grass, making it easy to teach your pup how to use them. Still, as with all pads, some training to teach your dog how to use the pads will be necessary.

Invisible / Electric Dog Fences. Invisible dog fences are another solution for letting your dog have free range of the backyard. They come in various designs (such as underground or radio) and range from affordable to splurge-worthy. And we promise – they really aren’t painful! See our full guide to electric dog fences here!

Dog-Friendly Screen Dogs. Getting a dog-friendly screen door can be another option if you want your dog to be able to go outside anytime. While some screens are simply designed to stop your dog from tearing apart the material, others use a magnetic closure that lets your dog simply push himself out into the yard (and back again). Of course this means leaving your house basically open to anyone, so it’s probably not the best solution if you’ll be gone all day.

Dog Door FAQs

Do burglars use dog doors?

While some owners may be concerned about the idea of an opportunistic thief sneaking through the doggie door, this is not very common.

For one, most burglars tend to avoid any homes with dogs – it’s just not worth the additional risk and trouble for them. After all, dogs tend to function like furry security systems.

Secondly, even dog doors designed for larger dogs aren’t exactly easy for a human to fit through.

Finally, if you are concerned about burglars breaking through the dog door, there are many dog doors detailed in this article that require your dog’s collar with a microchip to be near the door in order to slide open. These more tech-focused dog doors can put your concerns at ease!

What is the most secure dog door?

While the concept of what a “secure” dog door is may leave room for debate, we’d consider the High Tech Pet Electric Door (detailed in this article) the most secure in terms of intruders, due to its advanced locking and sensory functions.

When it comes to securing against the weather, we feel the PetSafe Extreme Weather door is best due to its three layers of flaps to keep cold winds outside and warmth inside.


As you can see, there are a number of options available for those in search of a quality pet door – as well as some decent alternative ideas. Be sure to decide the style that best suits your house first, and then compare the various models available before making your decision.

If you’re feeling especially brave, you can even build your own doggie door – see our collection of the best DIY dog door blueprints here!
