Medium Size Dog Doors

For the medium-sized dog, there are lots of options for pet door installation! We carry a variety of installation styles and methods that will work perfectly for your medium pooch. Whether you are looking for something more high quality or more economically friendly; something to install in doors, walls, windows—you name it—we’re here to find the best fit for you and your dog.

The first step in selecting a door for your medium dog is to measure them. Measuring correctly is essential, so check out this measurement guide for all the tips and tricks. You’ll want to go by height and width (not weight). The top of the flap should end up around 1” above your pet’s back and the width should allow around 1-2” on either side for your dog to move through comfortably.

A medium flap size will work for different size dogs depending on the manufacturer, so make sure to double check measurements. The average medium flap will be around 8”w x 12”h. Try cutting a whole in a piece of cardboard the size of the flap you’re looking at and see if your dog fits through.

If you are looking for something high quality and weather resistant for your medium dog, we highly recommend the EnduraFlap, which withstands extreme weather and holds up to heavy use by energetic dogs. Check out Endura for Walls, Endura for Doors, Endura for Sliding Glass and Endura for Windows depending on which installation location you want. Hale is another great brand that carries high-quality medium size dog doors. They even have a medium dog door screen mount for installation in door or window screens.

For dogs and cats sharing the Ideal Ultraflex Medium Dog Door is a great option available in medium dog door dimensions but light enough for a cat to push through. If you’re shopping on a budget, the Plastic PetSafe Medium Dog Door also works well for multiple pets.

You don’t have to worry too much about a full-grown adult accessing a dog door for medium dogs (more of a concern for extra large dog doors). However, to ensure maximum security, most dog doors come with a locking cover that slides over the pet door flap to block access. For sliding glass door and window mounts, we recommend a Charley Bar for added security. Electronic doors are also a great way to make sure unwanted guests aren’t entering your home. Due to limited technology, there are unfortunately no microchip pet door options for medium and large dogs. However, the High Tech Medium Electronic Dog Door will work for medium dogs by opening to a collar key worn around their neck.
