Dog Size

Another key when making a purchase of a dog door is the size of the dog, both width and height. By following the recommendations to properly take the measurements of each dog, you will ensure that the door fulfills its function and is comfortable and practical for the animal. In addition, you will know at what height to place it.

Easy Installation

It is very important that the dog door is easy to install, compatible with any material and that they do not complicate your life beyond three or four steps to follow. The barriers will not need screws in most cases and will be snapped on. With the doors,  you will need to make a hole.


The safety of your pet is the most important and the dog door must guarantee it. Some have magnetic closures or only allow access with a microchip. There are also doors with a second barrier to help you save energy at home, avoiding the loss of heat, cold or the entry of wind through it.

User Reviews

As always, user ratings on verified purchases are important. Although each case is different, the comments will provide you with information about the installation and placement of the door, the quality of the materials, and the colors. In addition, you will also be able to know if the dog is adapting well to its use or not.


As a final conclusion, you can look for cheap dog doors, but quality materials that guarantee the safety of your pet and at the same time your comfort are best. Safety barriers or fences will be very useful to avoid having to be constantly aware of where the dog is.

We recommend the entrance and exit doors only if you have an exterior space. In this case, you must pay special attention to the habits of the dog, its behaviors and, of course, its size. One of the key factors is to place the dog door at the perfect height: neither too high nor too low for the dog.
