A Shopper’s Guide to Small Dog Doors

If your dog is less than 15 pounds, then small dog doors may provide an ideal solution for allowing them to enter and exit the home at their discretion.

Pet owners often feel that installing a dog door simplifies their life, particularly if someone isn’t always home and readily able to let a dog outside to relieve itself or play. Small dog doors can be found in a variety of styles that can be installed in different places, including:

  • Traditional Exterior Doors
  • Sliding Doors
  • Walls
  • Windows

The sheer array means most homes have a location that could support a small dog door, as long as it is properly installed.

Security

One of the main concerns homeowners have about adding a dog door is security. Luckily, small dog doors don’t typically have openings large enough to allow a person to fit through, lowering the possible risk associated with a break in. Additionally, most small dog doors have additional security features to help close off the opening, giving you extra peace of mind.

For example, most dog doors come with a removable panel that can be used to cover the opening, creating a more substantial barrier. Others are available with special locking mechanisms designed only to open when the connected collar is within a particular range of the door. This can be ideal if there are other animals that could approach the door as they won’t be able to gain entry even if your dog can freely enter or exit through the entryway.

Measure Your Dog

Even if your pet falls below the weight limit typically associated with small dog doors, that doesn’t mean you should forgo measuring them. Generally, you’ll need to measure your dog’s height at the shoulder and width at their widest part, such as the chest, hip or abdomen. Once you have the measurements, you want to make sure that the opening itself is at least two inches taller and two inches wider than your pet.

This ensures they have sufficient clearance to move through the opening comfortably, making it more comfortable to use. It is important to note that, if your dog is a puppy, you need to purchase a dog door based on their possible size when they are full grown. Otherwise, they may exceed the size the door is designed to handle, and you’ll have to buy a new one to maintain the same level of access.

Installation

Whether or not a homeowner can tackle the installation of small dog doors on their own depends on a number of factors, such as the material surrounding the dog door, available tools, door design, and personal comfort level. Typically, sliding glass door insert variants are very easy to install, so most people will feel confident enough to handle this task on their own.

Small dog doors mounted in an exterior or storm door is more challenging, as the exterior or storm door must be cut into for the installation. Adding a small dog door in a wall or in the glass of a door are the most difficult installations to handle and may require assistance from a professional. This means there could be an additional cost, so factor that into your decision-making process.
