Looking for a dog door that's the real deal? Look no further than the Heavy Duty Dog Door.

Heavy Duty

We have used these heavy duty dog doors over the years and haven't found a more durable, chew proof, weather tight dog door. This dog door was designed by Minnesotans, so you know that it has been tested in the worst of winter and summer conditions. 

Easy to install and made to withstand all weather, you and your dog will enjoy this dog door for years to come. 

When your dog goes out, the entire assembly opens up on the mounting bar's hinges. When your dog returns, the fram stays and only the acrylic panel passes through the wall/door allowing the dog back in with the use of the hinges attached to the panel.
