Heavy Duty Dog Door by Gun Dog Mfg


Dog Doors by Gun Dog House Doors Co are some of the toughest, roughest and badest dog doors on the market today. These doors come with a lifetime warranty (for the life of your dog) that even covers chewing!

Key Features of This Door: Heavy duty super hinges. 1/4" clear plexiglass flap. Die cast aluminum frame. Weather tight. Chew proof and indestructible! Energy efficient. Fits dogs up to 120 lbs. Designed for large dogs -- it's a heavy and heavy-duty door. When your dog goes "out" the door, the inner clear plexiglass panel and the outer welded aluminum frame move. When your dog goes "in" the door, the welded aluminum outer frame stays stationary and only the inner clear plexiglass panel moves (see video below).

Note: Installed on the outside surface of a building, wall or door, etc. If you are installing this door on a wall or if you want the door opening to have a frame, you will need to frame the "tunnel" yourself - internal frame not provide with this kit.

Frame: 14"W x 20"H
Entrance: 11"W x 15"H

Best Price Guarantee
We offer a "Best Price Guarantee" on many of the products in our store. You can know for sure if one of our products is covered by the guarantee if you see this button on the product page: .

We constantly check out our competitors to ensure that we are competitive in offering you the best selection of dog products at the lowest price possible. If you happen to find a lower price at one of our competitors, let us know – almost always we can match it or even beat it! You can submit a lower price by contacting us through our online form or by calling us at 888-404-4076. When contacting us, we will need to know the exact URL of the competitor's product page where you found the lower price, and the product name, size and color that you want, so please be prepared with this information.

60 Day Returns & Best Returns Policy Guarantee
Here at The Uncommon Dog we’ve tried to create a return policy for our Dog Products that is as “customer friendly” as possible. And there are certain regulations and manufacturer restrictions that we have to adhere to. We want to be completely upfront with you about what those things are. If you happen to find a return policy better than ours at one of our online competitors, let us know (we do have some criteria, which are listed in our Return Policy). We'll match it.

With few exceptions, online retailers of dog products will either not accept returns under any circumstance or their return policies are very limited. Here is the truth: Return policies for dog products are very restrictive industry-wide because once your dog has had contact, it cannot be resold. We guarantee that everything you buy from us will be in brand new condition when you receive it, and we want to keep it that way.

We want you to be completely satisfied with your purchase from TheUncommonDog.com. If you are not satisfied with your purchase, you can return it within 60 days. Please fill out our Return Form to get the process started.

Please understand that we can only accept returns for dog products in brand new, never used, unwashed, unassembled, uninstalled condition, and your dog cannot have had any contact with the item whatsoever (no hair, no odor, no dog "breadcrumbs" at all). You can view the complete details of our Return Policy.

Restocking Fees
Some of our manufacturers charge restocking fees of up to 30% for merchandise that is returned for reasons other than manufacturer defect. Restocking fees (if applicable) are listed in the "Specifications" tab for each product on our website.

Refund Amounts
Also, it is important for you to be aware that if the dog product you purchased qualified for a “Free Shipping” promotion, the actual outbound shipping costs will be deducted from your refund amount (we will provide you with the exact amount when the return is processed).

Manufacturer Defect
If there is a manufacturer defect and you would like a replacement for the exact item you received, please contact us. If you would like a refund rather than a replacement, outbound shipping will be deducted from your refund.

Customer Reviews

Average Rating

I recently purchased this door for my 2 dogs. I have 2 pitbulls that have destroyed all other doggy doors, but this one has stood up to their chewing so far. It is a little loud when closing, but it's nothing a little foam tape can't fix.
