What to Consider When Choosing a Dog Door

To choose the perfect portal for your pets, consider their size, mobility, and personality. It’s a good idea for the following factors and features to be part of your decision.

Types of Dog Doors

Dog doors may be mounted in a traditional exterior door, sliding door, screen door, wall, or window. When choosing the right one for your home, consider material, security, and installation. Adding a dog door may mean modifying your home by sawing a hole into the door or wall, but professional dog door installers are available for hire if you prefer not to do the job yourself. While all dog doors are securable, all can also be compromised. One of the easiest ways to thwart would-be intruders is to install the dog door in a less-than-obvious place, such as a back door or window.

Door Mounted

The classic animal gateway is the door-mounted dog door with a simple flap your pooch can push to go in and out. The flap is typically securable to block access at those times when you don’t want your pet to go outside. You can also find models with two, or even three, flaps for extra insulation, advisable in areas where extreme weather is common. Installing this type of dog door is a relatively easy DIY job, but if you make an error, it can be pricey; you could have to repair, or even replace, the main door. The task involves drilling holes for mounting hardware, sawing the hole in the main door, then placing and sealing the frame of the dog door and putting in the flap(s).

Since it requires simply pushing the flap, a door-mounted dog door is simple for your pet to use, but it may also grant access to stray animals and wildlife—intruders have been known to use door-mounted dog doors to gain entry to a home. What’s more, small children may be able to crawl out.

Wall Mounted

Rather than a front-and-center position on your home’s door, a wall-mounted dog door can be placed in a less prominent area of the home. These dog doors can be a smart choice if you want your pet to have access to another area of the house, such as a garage. To install, you must drill a hole into the wall. And, depending on the thickness of the wall, a tunnel might also be needed for your pet to pass through. A wall-mounted dog door is the most complicated type to install as a DIY project.

Window Mounted

There are various different types of window-mounted dog—and cat—doors, to fit both sash and sliding windows. One common way to achieve a window-mounted dog door is to replace a pane of glass with a portal the pet uses by pushing a flap. If you don’t feel confident working with glass, you can hire a glazier to do the job. Renters and others opposed to modifying their home might consider a window-mounted door that slides back and forth. Since many of these models come with locking covers, you can leave it open for your pet to enter or exit, and then close and secure it when needed.

Sliding Glass Door Insert

If your home has sliding glass doors, consider an insert where a small area of the door is replaced with a flap-operated dog door, which will allow you to use your sliding glass door as you normally do. Many models have locks that independently secure the dog door. One of the most important aspects of such an insert is the height your pet must step over to come and go. Some manufacturers make sliding glass door inserts with adjustable “step overs” so dogs needn’t struggle, especially as they age. DIY install is possible but somewhat complex.

Electronic

If you’re concerned that wildlife, neighbors’ pets, or intruders might gain access to your home, consider an electronic dog door. These typically install in one of the main doors of the home in the same way as traditional dog doors. Electronic dog doors often have extra insulation, which is especially useful for those living in extreme weather areas.

Some electronic doors are activated via your pet’s vet-inserted microchip, while others have you set timers and lock modes. In both cases, you might need to program your animal’s collar or microchip so it connects to the door’s electronic mechanism.

Size

A dog door must be large enough for your pet to comfortably go in and out of without getting bumped or scratched on the way through. If the door is too short or the step over is too high, some dogs may refuse to use it. As a general rule, the height of the door should be 1.5 to 2 inches higher than the shoulders of your tallest pet. This is vital since a dog can be injured running excitedly through a too-low dog door. The step over at the bottom of the door depends on the size of your pet and the design of the door. When in doubt, opt for a lower step over so that a senior dog with mobility issues will be able to cross it without trouble or pain.

Materials

Dog door frames are commonly made of plastic or metal, while flaps are typically plastic or vinyl. Plastic flaps are relatively inexpensive and easy to install, but they yellow with age and accumulate scratches, making them unsightly. Vinyl flaps are more flexible and easier to push, so are often better suited to small dogs or cats as well as weaker, older animals. Vinyl flaps are generally secured with magnets and can be mounted very low for ease of access.

It’s prudent to choose a vinyl flap manufactured from a large sheet because it’s more likely to hang straight and not need adjustment. Flaps made from injection-molded vinyl tend to lose their shape quickly, so you may need to replace them rather frequently. And, because vinyl flaps can stiffen in cold climates, they may not function well during harsh winters.

Insulation and Energy Efficiency

Most dog door manufacturers state that their offerings are insulated and energy efficient. To ensure the claim is valid, verify that the door has at least some of the following features: an insulated flap, a double flap, weatherstripping, magnets, or other fasteners to keep the flap secure during high winds.

Security

Locks serve to both keep your pet in and unwanted visitors out. Because pet owners may not always want their animals to come and go freely, some dog doors have a knob or lever to manually lock the door. Not many dog doors, especially small ones, have these locks, so if you want one, be sure to check for it.

In addition to manual locks meant to keep your furry friend in, some dog doors offer other security components, ensuring your home is extra secure when you’re off-site. Types of protection available depend on the model and location of the dog door. Some allow you to lock a cover over a dog door, while others have traditional locks. Most small dog doors don’t have locks, but some have anti-raccoon features.

Ease of Installation

If you’re handy with a drill and saw, you may be able to install a basic door-mounted dog door. However, if you make a mistake, you may have to replace the entire door. For a wall-mounted dog door, you might be better off hiring a professional dog door installer to avoid damage to electric, plumbing, or other essential home systems.

FAQs 

The variety of dog doors available can make it challenging to keep up with all the information on features, benefits, and installation. Consider the answers to these frequently asked questions to guide you to the best dog door for your pets and your home.

Q. How do you install a dog door?

This varies greatly depending on the type, size, and location of the dog door. For basic door-mounted dog doors, you generally mark the opening, drill the holes for the mounting hardware, cut the opening, place the frame, and seal it with the material suggested by the manufacturer.

Q. How high should a dog door be off the ground?

A good rule of thumb is to install dog doors at least 3 inches from the bottom of your door to maintain structural integrity. However, the size and age of your dog also factors in; the dog door “step over” should be low enough for a small or senior pet to traverse comfortably.

Q. How big does my dog door have to be?

While this also depends on the size of your dog, the portal should be at least 2 inches higher than your pet’s shoulders so the animal can exit and enter without bumping into the top of the frame.

Q. Are dog doors a security risk?

Dog doors can be a security risk if they allow wildlife or other animals to enter or small children to crawl through. And, yes, burglars have been known to gain access to a home through the dog door. To lessen that chance, consider installing a locking or electronic dog door in a discreet location.
