Healthy Dog

Develop Happier, Healthier Pets

Once you have installed your eXtreme Dog Door, you may note that your doggies are suddenly spending more time outside, enjoying the fresh air and sunshine. More time outside means your dogs are getting more exercise as well. To sum it up, your dogs are becoming happier and healthier!

Dog Door Structure

Crafted From Robust Aluminum

We know that your extra-large dogs require a dog door that is enduring. This is why we designed our eXtreme Dog Doors from high-quality aluminum, derived from Australia. Shutting out severe weather even in the most severe climates, our dog doors are constructed to remain securely closed, thanks to their strong magnetic seal. There is no need to be preoccupied about your home’s security, as our eXtreme Dog Doors have an impenetrable aluminum panel that is held in place by 2 sliding corner locks that are only accessible from the inside of the home.

Easy DIY Installation

Door Installation - Step 01


To determine where your template needs to be placed on your door, you will need to begin by taking measurements of your pets. Next, use your pencil to draw on the template where you will be cutting your dog door opening.

Door Installation - Step 02


Take your drill, and use it to make holes in the 4 corners of your dog door template. Next you will need to make your dog door cutout by using your jab saw or jigsaw. Use your drilled holes for beginning points, and your pencil markings can be used as a guideline for cutting.

Door Installation - Step 03


Take each side of your dog door and insert them accordingly inside of the cutout location. Tightly clamp them together. Use your drill to make holes where the screws will be placed around the bottom, top and sides of the overlapping sleeve joints of the external and internal frames.

Door Installation - Step 04


Use your silicone gun to make a line of silicone that covers the outer frame of your dog door, on the inside and outside. Apply another bead in the area where the overlapping stops. Remove the clamps after 2 hours have passed.

1 review for eXtreme Dual Flap Aluminum Dog Door – XLarge

  1. Eric

    I do love this dog door however, after only owning it for about 6 months, I am now ordering my second set of replacement flaps. They keep ripping out of the top of the door.
    On the plus side… the installation was easy to do.
    I really like the the aluminum insert to lock the door. i do wish the locking switches were slightly larger, but they do work great.
    i have a large Lab Dane mix 110 lbs and he fits great.
    I also have a small dog, 16 lbs, who also uses the door with ease.
