Key Points
  • Automatic dog doors are a game changer for keeping your dog happy and free while also keeping your home safe. Your pet can come in and out, and the dog door will secure behind him.
  • As with any pet apparatus, durability is important in choosing your automatic dog door. Especially with the investment and installation to consider, you don’t want something flimsy that could fall apart.
  • Size is important to consider because some automatic doors are made for large dogs and some for small. Also, read the recommended weight limit.
  • Installation may be tricky. Make sure you research the method of installation, asking yourself if it’s something you can do. Hire a professional if you aren’t handy.

Having a sliding pet door has several benefits for both you and your furry friend. First, these electronic pet doors are the easiest way for your pet to come and go while keeping your house secure. They are also much better at keeping out drafts than standard pet doors as they close behind your pet and don’t rely on brittle rubber and magnets to seal, which can often break under regular use.  

Most automatic dog doors are controlled with an electronic collar. This ensures it’s only your pet coming through and not any unwanted guests like raccoons! Below you’ll find in-depth reviews, a convenient buyer’s guide, and frequently asked questions.

Today we’re going to take a look at the best automatic sliding pet door options on the market. Before you spend your hard-earned money, it’s a good idea to know what your choices are. We’ve included electronic dog doors that will work for a variety of dog breeds and door types.

Choosing the Best: What to Look For

We understand that you’re considering installing an automatic dog door for your home. There are several things you’ll want to keep in mind before you buy. When figuring out what you need for your specific pet, you’ll want to consider things like their size, outdoor habits, whether or not they’re microchipped, and more. Here are a few other things to consider:

Durability

One of the most important things about an automatic dog door is its durability. The last thing you want is to install something flimsy that does more harm than good. Choosing a dog door that is strong and secure will help with your energy bill, keep intruders out of your home, and work well with different weather. 

Dog Breed

The size of your dog will directly correlate to what size panel you’ll want in a dog door. If you have a larger dog, you’ll want to avoid small panels. Not doing so could cause your dog to get stuck or hurt. Most automatic sliding dog doors have a weight limit listed in their features to give you a good idea of whether or not it works for your pup. 

Installation

There’s no denying that some automatic pet doors are much easier to install than others. Who honestly wants a hassle when installing a pet door? It’s crucial to make sure you feel capable of installing the door at your home. If you don’t, opt for a different door or hire someone who’s able to get the job done. 

The Different Types of Automatic Dog Door (Sliding Pet Door): Pros and Cons Compared

If we’re being completely honest, in our experience, there are several types of dog doors but most sliding pet doors are the same. With that being said, there are smart flap dog doors and the traditional options that are completely manual. Let’s take a look at the pros and cons of automatic sliding pet doors specifically.

Pros!Cons!
Added securityTend to be pricier
Keeps other animals outNot one-size-fits-all
Multiple different programming optionsMay need to purchase additional batteries
Can work with more than one pet
More energy efficient than traditional dog doors
Easy to install

Our Criteria: How We Chose the Best

To compile our list of top recommendations for automatic dog doors, we researched many products on the market and took several key factors into consideration. Is the dog door weatherproof? Does it have a lock feature? Are the directions easy to follow and is installation fairly easy? Do the electronic components work well, and are they durable, especially any piece worn by the dog? Here’s our breakdown of some of the features in the products we’ve found to be the best:

  • Weatherproof: Any door protects the inside of the house from the outside, where elements abound. These automatic dog doors have electronic features, so it’s imperative that they stand up against rain and snow. Our overall best item is wind and waterproof with an airtight seal to also keep out cold drafts. Other items we recommended are also waterproof and energy efficient.
  • Installation: Installation of an automatic dog door can be tricky, so if you are not a handyman sort, we’d advise you to hire someone to do the task. The options we chose vary–some are best to install in a door, some are good to put in a section of wall, and our priciest option can travel with you, as it is installed in sliding glass doors. All these kits come with detailed instructions and measurements to aid in the process of installation.
  • Electronics: The truly automatic doors all come with separate smartkey devices that attach to your dog’s collar. The cutting-edge technology keeps other animals out of your home while allowing your dog to enter by sensing it’s approach and opening the door. The doors automatically lock behind your pet, whether entering or exiting. Take care that the device is firmly attached to your dog’s collar periodically. In our sliding glass door option, the door does not have automatic technology, but it’s great to use if you travel and enjoy staying in cabins or other rentals with your pets.
  • Price: Make no mistake–good quality automatic dog doors don’t come cheap. Most of them on our list range from around $500 to $2,500. However, our #2 Smartsafe Pet Door is much less–it averages around $120 for a small size and $200 for the large.
