Dog doors are windows of freedom for your pup. To keep them from charging out whenever they can, these doors are your last security defense. Making sure your dog door is secure so nothing and no one can get in is also something to consider.

If your pup is trained to go potty outdoors, then a doggy door makes your life that much easier, no longer do you have to be your pooch’s personal doorman. Whether you are at home or not, your pup may step in and out of the house at leisure. Make sure that your yard is well closed off though!

Dog Door Buyer’s Guide

Pet doors are becoming more and more advanced, integrating technology and smart functions into our households. We use our doors to only allow access to certain individuals and keep our homes safe. Why not the doggy door too? Pet doors are also intended for your pet to have easy access going in and out of the house while keeping out unwanted animal guests. We want to be sure our pets feel like they are part of the family with their own versions of household items and features. Read on to learn about how to pick the right door for you and your pooch.

What to Look for When Buying a Dog Door?


The size of the door is in direct connection to the size of your pooch. No matter how much you like the design of a smaller door, it simply won’t fit your Saint Bernard through, so don’t even try. Make sure you measure your dog and find the right fit. Ideally, the height of the opening should be at least 2 inches higher than your dog’s shoulders. As animal lovers, sometimes we have more than one furbaby at home.

The doorframe should be measured to fit your tallest and largest pooch. The best fit for your dog width-wise would also be two or more inches wider than it. For those of you with puppies with the potential to grow exponentially, make sure you find the right door to accommodate their full size.

Sensor or Not?

If you read through our list thoroughly, you would have seen a few electronic options. One of which has the function of scanning your already embedded microchip in your pup. This should be your first choice if your pooch already has a microchip. This takes away the hassle of having to put a collar on your dog all the time in the house. There are also ultrasonic and magnetic options that work well too.

Through the Door or Through the Wall?

There are two basic designs, a doggy door through the wall or through a human door. The ones that are installed into doors are easier to accomplish. As you can imagine, installing such a door into your wall takes an enormous amount of effort. If you have concrete walls, the task may seem near impossible. Where your door is placed is completely based on preference. What area of the house would you like your dog to enter through?


The choices are plastic or metal. For obvious reasons, a metal frame is more durable than a plastic one. If your dog is a larger breed or a full-fledged furniture destroyer, a heavy-duty metal frame could be better. However, for a tiny pooch, a plastic door will suffice.

Does It Add to Your Energy Bill?

A doggy door is essentially a hole in the side of your house. Such a hole can be tough to regulate. It’s hard to prevent against intruders, and difficult to keep your home cool in the summer and warm in the winter. Make sure the doggy door is weatherproof first of all, and above all else, properly sealed to protect your house against unwanted factors. Make sure the door and your house are well protected against the elements.

How to Train My Dog to Use a Dog Door

It’s better if this process is done in pairs. Find someone in your family who can assist you. Have one of you be on each side of the doggy door with the panel/flap in a fully open position. Have lots of your pup’s favorite treat ready and reward him/her when they hustle through the door when you and your family member call its name.

Repeat as necessary and gradually lower the flap little by little each time, until it is eventually fully closed. Your dog will catch on to the idea in no time. Remember that this is also a slow process and requires patience. Keep at it! Your pooch can do it!

Best Dog Door for Large Dogs

High Tech Pet Power Pet Electronic Pet Door

This door comes in two sizes, a medium and a large. The large accommodates pets up to 100 pounds! With all the electronic safety features and its ease of use, this is a great fit for larger dogs! You don’t want your large baby having to struggle through small doorframes and potentially damage your door or wall.

Best Dog Door for Small Dogs

SureFlap Microchip Pet Door

Made almost exclusively for small dogs, this is the perfect little door that only authorizes certain dogs to enter your home. There are different modes you can set it on (only out, only in, lock) to ensure your little canine tot doesn’t slip out unnoticed.

Best Electronic Dog Door

High Tech Pet Power Pet Electronic Pet Door

In my honest opinion, I’d opt for an electronic door for my pet. The installation and the setup could require more time and effort, but it’s worth it in the end with the convenience it brings. The two options we suggested for large and small dogs are the best choices. I’d personally lean towards the High Tech one for all its features and it’s user-friendly for large and small dogs.

The directional ultrasonic sensors and 4-way access control speak for themselves. Not totally sold on the security? The metal deadbolt lock is impossible to force open. And if all those characteristics don’t convince you, this one will. There is an automatic retract function if the door senses something obstructing the opening, like your pup taking its sweet time crossing the threshold. On top of that, this has the best weather insulation out of all pet doors.

Best Dog Door for Extreme Weather

PetSafe Extreme Weather Energy Efficient Pet Door

Made for extreme climates, this door will fully protect your home from the harsh weather outside. The 3-flap system offers maximum protection against the elements, with 3.5 times higher efficiency than the average door. Keep your home warm while still giving your pet the freedom to come and go.


That was a lot of information to swallow, but if you follow our tips, the right door is just a click of a mouse away. A good doggy door should empower your pup and make it feel even more at home with the freedom to come and go. Training your other pets to use the door is also easy with lots of reinforcement and treats! Most pet mommies and daddies out there can agree that dog doors have made their lives and the lives of their pets easier.

We hope with our help, you will also come to feel this way. One more thing, make sure the door you choose depends more on the features and safety functions rather than the price. The safety of our home and our pooch are priceless!

Expert Tip

Patience is a virtue when training any pet. Aside from that, you also need consistency. Stay consistent in your training methods and do not deviate from the plan. Your choice of pet door should also be consistent. A lot of options have a money-back guarantee, look for these ones when you are trying to find the right fit. Chances are, your dog will like one type more than another. Once you find their preference, stick with it and keep at it.

Did You Know

A really cute and factual thing is that if you have multiple pets, the first trained one will most likely demonstrate and take it upon itself to teach the others. This will be an incredibly adorable process to watch.
