FAQ

What's the difference between the single flap and the double flap?

The double flap option provides increased insulation against the cold. Both options have magnets on the flap to keep the door sealed in wind.

I want to get the large pet door for my dog, but I am concerned about a person fitting through it.

All Dragon Pet Doors come with a locking cover. This cover can be used to keep you doggy in. It also can be used to keep intruders from entering your home. It slides into the interior frame.

How do I know what size is best for my dog?

When installing the pet door you want it to clear the top of your dog's back by 1-2 inches, minimum. To give your pet the most comfortable pet door possible, make sure the step-over is less than 1/3 of your dog's height. Lastly you want the width of the door to be big enough to allow your pet to go through without touching the sides. Here's a measure your pet with tips on how to determine the correct size.

Are replacement flaps available?

Yes, you can buy Dragon replacement flaps.

Where can I install the Dragon Pet Door?

The Dragon Pet Door has multiple Installation options. You can install it in Regular Doors, as a Wall mount, Aluminum Sliding Doors, Vinyl Sliding Doors, Sash Windows, Vinyl Windows, and Horizontal Windows.

Can my small and large dog share this pet door?

Installation Instructions

PARTS LIST 

1 Window Insert with a Pre-Installed Dragon Pet Door (single or double flap)

1 Foam Weather Strip

1 Locking Cover 

 

Step 1: Loosen the thumb screws at the end of the pet door insert. This allows the spring mechanism to move freely up and down. 

Step 2: Open your window and insert the panel into the window track. Push against the spring mechanism to expand the panel into the upper window track. Once it is expanded the full height of the window, tighten the thumb screws. 

Once you are certain the window pet door sits properly in your track, proceed to step 3 to apply weatherstripping. 

Step 3: Apply the foam weatherstripping by peeling back the paper to expose the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install it on both the top and bottom, trimming to fit as needed with scissors. 

Repeat steps 1 and 2 to secure the window pet door in your window track. 

Note: Since there are many window styles, you may need to modify your installation using shims or similar materials such as foam weatherstripping. If there is a gap, you can use shims to even out the pet door.
