Many of our customers choose to shop for a pet door based on size guidelines such as small, medium, large and extra large.  The one main problem with this method is most obvious when selecting an extra large dog door.  A tall and skinny Great Dane is most definitely an extra large dog, but so is a Saint Bernard, an obviously wider dog than a Great Dane.   So measuring your dog for the best fit will save you time, frustration and money.  Every manufacturer has different size guidelines.  For example, Ideal's extra large dog door measure 10 inches in width while Hale Pet Door's extra large dog door is 15 1/2 inches wide.  Many manufacturers go even beyond extra large to sizes such as super large and giant. If you have one of the largest of giant breeds, check out the Hale Giant Dog Door where the opening measures 15 1/2 x 27 1/2. 

An extra large pet door will take up a lot of space in your wall or your door, so it is very important to evaluate the space available for an XL pet door before purchasing.  Specifically, if you are looking for extra large dog doors for sliding glass doors, they will take up a sizable amount of the opening. Will people still be able to enter and exit through the sliders after installing a giant or extra large doggie door?


Additionally, check your local fire codes since having too small of an opening for people to pass through the sliders may be considered a fire hazard.  Prior to purchasing your extra large pet door for sliders, open up your sliders to the width of the patio panel and check to see if the remaining available space is sufficient for people to come and go through the sliders.  Dog doors for sliding glass doors are expensive doors to ship back, so you want to make extra sure that the one you buy will work for you so you don't have to go through the time and expense of making an exchange.

TIP: If you are planning to install an extra large dog door for walls be sure to first determine that no plumbing or electrical wiring is in the way before cutting the hole.

Another point to consider when shopping for really big dog doors is that when your big pooch actually uses the doggie door you will lose some of your home's heat or air conditioning. This cannot be helped, just like when people go in and out their house doors, home energy escapes. If this is a concern for you then you'll at least want an energy-efficient dog door that is as air-tight as possible to keep heat and AC contained when the dog door is not in use.
