Frequently Asked Questions about Dog Doors

Are dog doors safe?

Dog doors are safe for pets and people, and many have added features to make them even safer and more secure. If you are worried about intruders gaining access through a larger dog door, look for a locking dog door or one with a security plate you can put in when you're away. Locking doors also allow you restrict your dog's outdoor access during certain times; ideal if you're worried about letting your dog out at night or while you are at work. High-tech features like microchip or collar activation ensure that only authorized pets can get in and out through the dog door. This helps keeps wildlife, people and other pets out and your indoor pets inside safe and sound.

Can you put a dog door on a glass door?

You can put a dog door on a glass door, but it may be more or less difficult depending on what kind of glass door you have. The simplest dog door for a glass door is a sliding door panel that inserts easily into the sliding door track with no cutting. You can also find dog doors that install within glass panels, although you will likely have to hire a glazier, carpenter or experienced handyman to install them. Most dog doors are designed for installation in doors or walls, but there are many newer options to fit a variety of pet door needs.

Do dog doors let other animals in?

Dog doors can let other animals in, but there are some dog doors designed to prevent that from happening. Microchip or collar tag-activated doors only open for the pets whose chip or tag is programmed into them, preventing the neighbors' cat or a friendly raccoon from sneaking in on the sly. Other locking pet doors have settings for unlocked, fully locked, in-only, or out-only, so you can control access during certain times of day or when you're away.

What are the best types of dog doors?

The best types of dog doors will depend on your particular needs, but the best dog doors should be weatherproof, sturdy and easy for your dog to use. Look for dog doors designed for installation where you need them; there are dog doors for walls, doors screens, sliding doors and even windows. Choose from a range of dog door types, including dog flaps, insulated pet doors, automatic dog doors, and smart or microchip-activated dog doors.

What size dog door do I need?

You need a dog door size that allows your dog to easily come and go, and it needs to have a step-over height that he can easily negotiate. Measure your dog standing up at his tallest point, which is usually just below the neck and between the shoulder blades. The top of the flap, when mounted, should be at least 1-1.5 inches taller than this measurement; most doors require a mounting height of at least 3 inches to preserve the structural integrity of the door. Next, measure your dog's width and add 1-2 inches to that measurement to get the right flap width. Choose the pet door size that most closely fits your dog's measurements and mount it at the right height for your dog's size, age and abilities. Chewy includes flap opening dimensions and a size and weight guide on every dog door listing to make it easier for you to figure out what size you need.
