What You Need to Know About All Pet Doors

For pet owners, the idea of having a pet door is often enticing. This allows your animal companion to enter or exit a particular space with ease, without you having to be available when the need arises.

Nearly all pet doors can be found in a variety of styles that can be installed in different locations in or on your home, including:

  • Traditional Exterior Doors
  • Sliding Doors
  • Walls
  • Windows

The numerous options mean that nearly any home could support a pet door as long as it is correctly installed. However, there are points you need to consider before making a selection, as where you choose to place the pet door dictates how difficult the installation will be and whether you may need help from a professional.

Sizing

One of the most important features of all pet doors is the size. Typically, pet doors are available in four primary sizes, most commonly ranging from small to extra-large. However, there may be some variance in the actual opening measurements from one manufacturer to the next, so it is important to properly measure your dog and review the details of the door before making a purchase.

Additionally, if your dog is still a puppy, and likely to grow, it is wise to select a pet door based on their anticipated size once they become fully grown. Otherwise, you could find yourself shopping for a replacement sooner rather than later.

Security

While all pet doors add a level of convenience for the homeowner, they also inherently create a security risk. Whenever the doorway is unsecured, anything of a suitable size could pass through the space, including other animals and even intruders.

Many pet doors come with some basic security features. For example, a solid sliding door is often part of the design, allowing the entry point to be closed off when necessary. Additionally, some dog doors feature electronic locks that are paired to a special collar, ensuring the door only opens when your pet approaches the entrance, a particularly helpful feature for larger dog doors that a person could potentially pass through.

Installation

When most people picture pet doors, they often visualize them installed in a traditional exterior door. While this is certainly an option, there are also versions that function as sliding glass door inserts or are intended to be installed in other materials, like walls or storm doors.

Most homeowners can safely manage putting in a sliding glass door inserts, but the others may require professional installation depending on the tools you have available and your personal comfort level, particularly those being added to a sheet of glass or through a home’s siding or masonry. Having a professional install the door typically adds an extra cost, so this should be factored into your purchase decision.
