Small (0-20lbs)

Thank you for your interest in Gun Dog House Door® small dog doors. These small pet doors are designed to accommodate dogs up to 20 pounds. Our chew-proof aluminum dog doors come in two designs. The first is our spring hinge version, designed after our world-famous Heavy-Duty Dog Door®, which is the more weather efficient version. The second is our easy swing version, designed after our Easy Dog Door®, which is less weather efficient but easier for tiny or arthritic dogs to use.

Doggie doors offer a variety of perks for pets. Small dog breeds tend to have high energy levels and benefit from being able to go outside whenever they need to get physical exercise and mental stimulation throughout the day. Similarly, they can access the outdoors for bathroom breaks without needing to alert you first. This is essential as your dog ages and can be more prone to accidents inside the house.

Don't let the spring hinge Heavy-Duty Dog Door intimidate you or your pet! The force to move it is less than 1.5 lb., which is like opening a cabinet. Check out a YouTube video that a non-sponsored person posted demonstrating their chihuahua using the Heavy-Duty Dog Door®. If a 3 lb. dog can use this door, your pet can use any of our spring hinge small dog doors, given the proper acclimation process.

If your application requires Trim Kits and Closing Panels to make a complete "kit", please note that our products are sized specifically (S, M/L, and XL). Browse small pet doors and accessories below.
