Step #1:
Measure the belly height of your pet from ground level to his underside to find the correct height of the door opening. Bottom edge is usually 6" to 12". Do not mount flush to ground.
For the Heavy Duty Dog Door™ cut the opening 12-1/2" wide x 17-1/2" high. For the Big Dog Door™ cut the opening 16-1/2" wide x 25-1/2" high.

Step #2:
If mounted on garage or house wall, frame the depth of the wall to form a tunnel through the wall. (Use 2" X 4" or 2" X 6" material.) If needed, add a least a 1/2" x 1 1/2" flat outside mounting surfacing.

Step #3:
Place door over opening and use the enclosed two 1 1/2” wood screws to hold door to opening.

Step #4:
Show dog how to use door. Your dog will learn to use your pet door almost at once, but there are a few which may be a little nervous at first.


The most important rule is to be patient.

Do not let the dog have a bad experience or it may become frightened.

Most dogs can be trained to use a pet door in a matter of hours. Your dog will respond to encouragement, repetition and play in particular.

Alternatively, use the door flap as part of a game - throw a ball through, for instance. As your dog responds to your encouraging calls, help it through the door, patting and congratulating it. Repeat the game several times, continually encouraging the animal with positive gestures and comments. Within a short time your dog will be totally familiar with its pet door and use it happily on its own.

I have seven-week old lab pups that use these doors, naturally, your dog will learn too.

Installation Tips:
Install 1/8" felt or rubber weather stripping on surface of building or door. Do not put rubber weather stripping on Gun Dog House Door®.

NOTE: If your door does not close at the bottom, the door is installed incorrectly. Unscrew door and move 1/4" lower. If there is a gap between top strap and upper doorframe, move door 1/4" higher.

Measure height.

The Heavy Duty Dog Door® and Big Dog Door™ are installed
on the outside of a house door.

Determine Height
To find correct height of the hole for your dog, measure the belly height of your pet. (Average installation is six to twelve inches.)
Mark the height in pencil on one side of your door.

 


Drilling and cutting hole
The Heavy Duty Dog Door® hole size is 12-1/2" x 17-1/2". For the Big Dog Door™ the hole size is 16-1/2" x 25-1/2".

Drill half inch in each corner. Insert jigsaw into drill hole and cut out hole. See photo 1.

If installing on a steel door, cut hole 6/8" (3/4") larger, glue 3/8" pine, cedar, or plywood strips to inside of the opening.
See photo 2.

If installed on a raised panel door, cut hole in center of door 6/8" (3/4"). glue 3/8" pine, cedar, or plywood strips to inside of the opening to cover styrofoam and install trim to inside/outside of door surface.
(See our Pet Door Trim Kit)

If installing in a hollow
core door
, use four strips of wood the same width as the hollow between the panels in your door. Position the wood so that they are flush with the edges of the hole. Either glue, nail or screw the strips.
Frame the outside/inside hole with (2) inch by (1/4) inch lengths. Again, either glue,
nail or screw to door surface as the photos illustrate.
