What Pet Door Size Should You Buy Based On Your Dog's Breed

Grace Fuh March 21, 2018

Once you have decided to buy an Endura Flap pet door, you might be wondering what flap size you need to get. Pet doors are not "one size fits all,’" and the door dimensions will vary as per the size of your pet. Well, we just made it a lot easier for you!

Choose the most suitable pet door size you need as per the breed of your furry friend.

Pet Door Size Chart by Breed

Pet Door Size	Pet Door Dimensions	Suitable For
Small	6” x 7”	Cats, Chihuahua, Yorkie, Pomeranian, Maltese, Papillon
Medium	8” x 15”	Beagle, Pekingese, Cocker Spaniel, Poodle, Dachshund
Large	10” x 19”	Labrador, Boxer, German Shepherd, Golden Retriever, Bulldog, Doberman
Extra-Large	12” x 23”	Irish Wolfhound, Great Pyrenees, St. Bernard, Rottweiler, Old English Sheepdog, Great Dane

In case you have more than one pet, make sure that the step-over height is low for the smaller pet, while the maximum height of the flap should allow the tallest pet to get through as well.

For the best fit, we recommend measuring your pet to ensure that their dog flap will fit them.

We've also made the following graphic for you to find the perfect size for your pet. Just find their breed, and see what size they use! It's worth noting that this is only referential, and heights can vary within a breed. The best thing to do is measure measure measure!

Hi Shuchi,

We recommend that the pet door be at least 1" higher than the tallest point of your dog’s back (could be near their withers or their tailbone).

For door installations, we recommend not installing lower than 3" from the bottom of the door in order to maintain the integrity of the door. Wall mounts can be installed a little bit lower than this.

Hi Barry,

This is an excellent option for door installations: https://enduraflap.com/products/pet-door-for-doors-double-flap. The rough cutout will need to be rectangular. Please feel free to contact us at 800.826.2871 or customerservice@enduraflap.com with any questions!

Happy holidays!
