A pet door is one of the best investments you can make for yourself and your pet. The benefits of a pet door range from safety to added freedom for your furry friend, and it even eases the burden of having to carry, escort, or ask your pet to go outside.

Pet doors have been around for a while, but the kind we’re seeing today is far more advanced than ever before. They come with insulation technology and features that make it impossible for intruders to take advantage of these little entrances.

However, it’s important to hire a professional to install your pet door, as they’ll pretty much do everything for you except train your pet to use it. In the end, having a pet door will improve your and your pet’s quality of life as access to the outdoors is important for both humans and creatures alike.

Frequently Asked Questions:

Q: How much does it cost to install a pet door?

A: The cost of your pet door depends on factors such as where it’s installed, how tricky the placement is, and the type of pet door that you choose. Installation can cost just over a hundred dollars while the pet door itself can go for as low as a couple of hundred dollars, with the costliest one going for just over $900.

Q: Are dog doors hard to install?

A: Installing a permanent doggie door is not a job that anyone can do, especially when dealing with a surface like glass. Protective equipment is needed because of the risks involved and it’s not uncommon to get an injury from working with glass. One must also consider the pet’s age because you don’t want your best friend to outgrow their door. 

An electric drill may be used, measurements must be taken and there’ll probably be a sealant involved.  So, such projects are best undertaken by professionals that have done them before, otherwise, you may damage your  glass door. 

Q: How do you install a doggie door in a glass door?

A: To install a pet door in a glass door, you need to start by measuring your pet’s width and height. Then, a panel will be installed into the glass and it’ll have to be dry fitted to avoid any size-related issues. The panel is then fitted in, screwed in, and fixed in nicely to make it secure. You then have the flap fitted in at the end. For a glass sliding door, you want to have your pet door in a place that doesn’t interfere with your movements in and out of the house.
