Dog Doors for Small Dogs

Whether your best friend is a Cavalier King Charles Spaniel or a Shih Tzu, at Hale Pet Door, we have the perfect small dog door for you both. Our premium quality small dog doors are made with the finest materials and expert craftsmanship—and we offer a few different sizes to accommodate various small dog breeds. Our models range from easy-to-install door model pet doors to ones that can be used in walls, screen doors and windows, and sliding glass doors.

If you’re tired of being a “doggie doorman,” a dog door lets your furry friend do their business whenever they like, day and night, without disturbing you and your family. For older dogs who may need to go to the bathroom more often, a dog door can be a welcome addition to your home. A dog door for wall use can also be used to provide access to a room that’s usually kept closed.

The Best Dog Doors for Small Dogs

We take great pride in the premium materials we use and the care, expertise, and attention to detail that goes into every dog door we make. 

  • The Best Materials – Our frames are constructed from extruded aluminum and have steel-reinforced corners, which improves their strength and durability. We also use steel and zinc alloy components, mold-resistant carpeting, and a protective finish for many years of use. 
  • Energy Efficient – Our weatherstripping design makes our doors more energy efficient than others on the market, to help you save money on your heating and cooling bills.  
  • Safe and Secure – A high-density polyethylene security cover stands up to the harshest weather conditions, and it can be securely locked in place with a steel pin lock.
  • Many Options – We offer various models, including kennel doors and custom pet doors. We can make them for interior or exterior walls, doors, and/or windows. 
  • Professional Installation – Most models can be installed by a “do-it-yourselfer”, or you can let our trained professionals install your dog door. Expert installation is available across the U.S.

Sizes for Small Dog Doors - Custom Sizes Available

Unlike many of our competitors, we don’t just offer small, medium, and large sizes of dog doors, because not all “small dogs” are created equal. 


Dog Height and Width

Dog Door Size


Height - 9" to 13"

Width - 3" to 5"

Small Medium


Height - 12" to 15"

Width - 3" to 5"

Tall Small Medium


Our “small-medium” size is a great fit for most small dogs including Chihuahuas, Pomeranians, Papillons, and Yorkshire Terriers, and slightly larger small dogs like the Toy Fox Terrier and Miniature Pinschers. The “tall small medium” size may be more appropriate for your Pekingese, Pug, Miniature Poodle, and other breeds with longer legs. Depending on the width of your small dog, you may want to consider a medium dog door to accommodate them. We do not recommend the “small” size for any dog breeds (and only the smallest cats).

Pet door size is extremely important. While your four-legged friend might be able to “squeeze through” a dog door that’s a bit small for them, over time this can affect their health and well-being. A low-stress, perfectly sized dog door for your pooch is our mission. Do you need an extra small dog door? We also make custom sizes.   

For exact dimensions of our pet doors for dogs (and how to measure them), see our Sizing Tips and Information page. 

What is the Size of a Small Doggie Door?

Typically, a small dog door should be approximately 6.5 by 9.5 inches. However, as small dogs come in many shapes and sizes, some may need extra space. At Hale, we offer sizes for different breeds.

How Do You Measure a Dog for a Dog Door?

Measure the width of your dog at their widest point. Then measure their shoulder height. For dog doors that include a built-in rise (step-over), measure how high they’re able to lift their paws. Use this pet sizing guide to help you measure your dog.
