Gun Dog Doors are commercial-grade, heavy-duty pet doors constructed of welded aluminum with a clear plexiglass pet flap/door. These pet doors are chew proof, unbreakable and easy to install. Choose from a variety of sizes and styles that will fit your dog's needs.
Note: The Heavy-Duty Gun Dog Door model is not recommended for small or timid dogs. They are very heavy and have a spring loaded flap closure system that could injure smaller pets. Instead see the Gun Dog Easy Pet Door which is not spring loaded and is easier for timid pets to use.
