Gun Dog Pet Door for Your House

This Dog Door was initially introduced as the "Easy Dog Door" and the "Easy Big Dog Pet Doors" and was designed to address two problems with the original Gun Dog House Door and the Big Dog Door:

    1. The first drawback of the original two dog doors is that they are quite loud in use. The two frame sections slam together and both bang against the wall when the dog passes through.
    2. A second problem is that the two dog doors are relatively heavy and therefore difficult to use by small dogs and cats.

The "Easy Dog Doors" consist of a 1/4" polycarbonate free-swinging flap inside a diecast aluminum frame. The hinges are not spring-loaded and there are no magnets for closure. A weighted bottom helps stand up to some wind. Note that polycarbonate is an extremely tough, durable material. It is far more durable than plexiglas or acrylic.

The optional closing cover mounts on the opposite side of the door or wall from the pet door (it will not install over the pet door. A sturdy, 1/4" thick polypropylene panel slides down provided aluminum channels over a 14" x 20" opening for the "Easy" door or 18" x 28" for the "Easy Big" door .

If you want this closing cover to be proof against someone lifting from the outside, drill a hole through the cover and wall on the inside and insert a short dowel.

Note The 5 year warranty even covers chewing!

  • So durable!! review by Grey
    5 5 So durable!!

    This door is so durable!! the flap is hard and very clear so my dog can see going out and in which he likes. We had the darker flaps before and he would never use them. With this door he uses them like a champ. I just got a puppy and he tried chewing on the door but I got him to stop and there were no marks. I am so happy with this door. The quality is great it is durable and insulates well. Great door.

  • Simple Pet door review by Penelope
    5 4 Simple Pet door

    Simple construction will hopefully lead to years of use. Like the very large pet door size (15" wide x 23" tall) for my big dog. Very clear hard plastic-type flap that lacks a magnet or spring so it depends on weight to keep it closed. Would probably not recommend if you live in a windy area. If you want a locking cover you have to buy it separately

  • Looks great, sounds great review by Arturo
    5 5 Looks great, sounds great

    This pet door is so sleek and streamlined - doesn't look bulky at all. There are no magnets, so it's really quiet (doesn't scare my dog) and is really easy for even the smaller ones to go through. Definitely not for you if you need something with great insulation because it's a free swinging door, but we installed this in the doghouse outside, so that wasn't an issue.

  • Easy to use review by Happy Dog Owner
    5 4 Easy to use

    This pet door works great for my outdoor dog run, I have 20 pound dogs and a larger dog, so the flap needed to be easy to push and see through. There is no resistance to this flap, my only issue is that it takes a long time to "settle" after they pass through it, since it swings back and forth for awhile. But very high in quality and I don't think it will ever break.

  • Sturdy, Well-Made, Excellent review by TJ
    5 5 Sturdy, Well-Made, Excellent

    We needed a dog door in a gate behind our house that sections off our dog run. We wanted to keep the gate closed at all times to conceal the dog run, but needed to give our dog access since that's where he goes to the bathroom. Our needs were very specific because it needed to attach to our iron gate, which is a different thickness than a standard door or wall. We also needed it to withstand the elements that comes with being outside. This does both. The frame is rust-proof aluminum and flat, allowing us to screw it to the back of our gate. The "flap" is hard plexiglass, so no warping and very rigid. The door is extremely well-constructed. I can see this easily lasting longer than I'll be alive. Highly recommend.

"Special" Dog Door Training for the "Timid Dog"

Installing On a Wall:

The Heavy Duty Dog Door ® and Big Dog Door™ are installed on the outside surface of a building, wall or door, etc.

measure height of your pet before install using a tape measure
Measure height


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 from 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.

Frame the depth of your wall to create a tunnel space for pet access
Example of tunnel
in frame wall

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.

install the frame over the rough cut out using hardware provided
Cut opening, if
needed add a 1-1/2"
flat mounting surface.

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.

Problems…see Special Dog Training Instructions at end of page

a perfectly installed product will close at the bottom with no gaps
This is how an
installed door looks.

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.


Installing on a house or garage door:

Make sure you have the correct opening size by measuring your pet

Measure height.

Step #1:

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 6"-12".)  Mark the height in pencil on one side of your door.

we suggest to use a jigsaw to cut the opening of the pet door for a clean look
Jigsaw cutting to each
(1/2") drilled corners

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 a half inch hole into each corner. Then draw lines to connect the corners. Insert jigsaw into drill hole and follow drawn lines to cut out hole.

These products have the ability for multiple install locations like raised panels doors and in steel material
Steel door: Note hole is cut 3/4" larger to allow for 3/8" thick wood inserts. 

Step #2:

If installing on a steel door, cut hole 3/4" larger, glue 3/8" pine, cedar, or plywood strips to inside of the opening

If installing on a raised panel door, cut hole in center of door 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.

for hollow core installations use wood reinforcements making sure they are flush wtih edges
Hollow core reinforcement wood strips 

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" x 1/4" lengths.

Silicone caulking is necessary for added insulation value


Step #3:

Use silicone caulking around trim kit for added insulation. To quiet door closing, staple 5/8" of the window felt to the sides and the bottom of the pet door.

Drop-in Closing Panel Installation Instructions:

closing panel should be installed on the inside of the building or door location
Install channel on inside of building

Step #1: Closing panel is installed on the inside of building or door.

Step #2: Construct a 2" wide frame on inside mounting surface.

Step #3: Place channel angle one inch from dog door cut opening.

Step #4: Install one-inch tabs at the base of each channel.

Step #5: Slide heavy-duty closure into channel. Remove as needed.

Guillotine Closure Installation Instructions:

Use the template provided to begin the 3 steps to start install on guillotine closure

Step #1:

Place panel against wall as a template. Install each channel so the panel slides in its grooved track.

Step #2:

Drill hole or install a eye hook in panel. Install two pulleys to ceiling and attach a cable/rope to the 3/8" polypropylene panel.

Step #3:

Slide polypropylene panel in channels as needed.

"Special" Dog Door Training for the "Timid Dog":

Great for all pets, even puppies can use, just be sure to input not too high or low
This little 7 week old Lab pup is already a pro at using the Gun Dog House Door®.

Whether you have an adult dog, or a new puppy, teaching him how to use a Gun Dog House Door® (GDHD) will be done the same way.

When you install your dog door, make sure you measure the "rise" of your dog (the measurement from the floor to the lowest part of your dog's chest or stomach). This measurement tells you where to place the "bottom" of your dog door. The bottom of your dog door should be an inch lower than the "rise" of your dog. If you have a puppy you will need to install the dog door one inch from the ground; and you will need to re-install it at higher intervals as your puppy grows. Another option is to take an educated guess as to how tall your dog will eventually be, install the dog door at the appropriate height, and construct a "puppy-ramp" so your puppy can reach the dog door and go through it comfortably.

If you have a small and big dog check out Gun Dog to give your pets some freedom

Once the frame of the GDHD door is installed in a wall or door, leave the GDHD off at first. Have someone stay inside with your dog while you go outside. Call your dog through the "hole" (door frame without the GDHD). When he goes through and comes to you, praise him lavishly and give him a treat. Now have the person inside the house call him through the "hole." When he gets to them, they should praise it and offer a treat as well. Do this at least 3 times and no more than a dozen. After this, your dog will know there is a hole in the wall or the door especially for him.

as a pet grows you may need to adjust the height of the install, check out our measuring guide for help

Leave the GDHD off the cut opening for one full day. Encourage him to use his opening by not letting him use the "real" doors. Instead, you use the real door and say to your dog, "Go to your door!" pointing in the direction of his dog door. You may need the help of someone inside to "help" the dog find his new door. After a half a dozen times, your dog should like this new game! If you have a very young puppy, do not expect them to learn "Go to your door" for many weeks or months; still give them the command in a happy voice, and have someone inside show them where their door is every time. It sometimes helps if you are outside (after going through a real door) and someone else helps your dog or puppy find the doggie door as you call him from outside.

On the second day, install the GDHD. Now, you will need to repeat the same exercise as when you first sent your dog through the "hole." But this time, the person on the same side of the door as the dog will need to "push" the GDHD open for him. Each time the dog goes through the door, push the GDHD less and less for him. It is important that the dog gets used to the feel of the GDHD on the back of his head so once your dog has begun going through the door, let go of the GDHD so he feels it on his head and body as he goes through the door. Eventually the dog will need to push the GDHD by himself and dogs are usually hesitant to do this at first. He will probably put his nose down by the bottom of the GDHD and wait for the GDHD to move (after all, it has up to now). At this point, push the GDHD slightly so that your dog can see it is a moveable object, let the GDHD bounce back to the closed position. The best way I can explain it is that you are "poking" GDHD using short, quick pokes. This gives the dog a glimpse of an opening and encourages him to poke the door himself. At this stage, some dogs begin going through the door with ease, others become quite excited, but still haven't figured out that they can push the door open. If your dog will not push the door open by himself yet, remove the GDHD and install a piece of carpet onto the opening. You want the carpet to have a least a _” opening on the sides and bottom. The dog should feel more comfortable pushing the carpet on its own. After 2-3 days, install the GDHD and with our enthusiastic encouragement and praise, your dog should be able to push the GDHD now with no problem

The Gun Dog Easy Dog Door is lighter than the others because the hinges aren't spring loaded and there are no magnets to assist with closure; this makes it easier for smaller dogs and maybe cats to use the door.

The Gun Dog Heavy Duty dog door has a rigid door that includes a warranty covering chewing damages. This is the original door that was created by Gun Dog to address all the issues the owner of the company ran into while operating his kennel for large lab retriever dogs.

The Gun Dog Big Dog Door is the same as the heavy duty door, but it just offers a larger flap size of 15" x 23".

Yes - as it is much easier to push open, it would be the one to use in a kennel with different size dogs.

You can use this door along with the Gun Dog Closing covers.

Nope, you can use this door on a residential application if needed.

The flap is fairly heavy, but there really is no seal between the flap and the frame, so it isn't the best as far as energy efficiency.

It is a thick rigid polycarbonate.

Heavy aluminium.

The door is just a flap frame, so there is no exterior frame to finish out the opposite side.

Yes, but you need to have your contractor build and seal up a tunnel framing out the interior.

Not with this pet door.

Absolutely! They're near indestructible - that is what makes them good for kennels.

No, Gun Dog "Easy" Dog Door includes one frame with flap which allows it to be installed in virtually any application with proper framing
