No more constantly opening and closing the door for my dog to go in and out, and no more scratched up doors from her eager paws. If you have an extra large dog like mine and are considering getting a sliding glass door dog door, here is my buying guide to help you make the right decision.

Size

The first thing you need to consider when buying a sliding glass door dog door for an extra large dog is the size. Make sure to measure your dog’s height and width, including their shoulders, to ensure that the dog door will be big enough for them to comfortably fit through. It’s always better to go a size up if your dog is in between sizes.

Material

The next thing to consider is the material of the sliding glass door dog door. For extra large dogs, I recommend choosing a sturdy material such as aluminum or heavy-duty plastic. These materials are durable and can withstand your dog’s weight without breaking or warping over time.

Installation

The installation process of a sliding glass door dog door can vary depending on the brand and type you choose. Some may require professional installation, while others are easy enough for you to do yourself. It’s important to read reviews and instructions carefully before making your purchase, especially if you plan on installing it yourself.

Security

Safety should always be a top priority when considering any type of pet product. Look for sliding glass door dog doors that come with secure locking mechanisms or ones that can be easily locked from the inside when not in use. This will prevent any unwanted animals or intruders from entering your home through the pet door.

Weatherproofing

If you live in an area with extreme weather conditions, it’s important to choose a sliding glass door dog door that offers good weatherproofing features. Look for ones with insulated flaps or double flap systems that can help keep out drafts and maintain comfortable temperatures inside your home.

Maintenance

Last but not least, consider the maintenance required for your chosen sliding glass door dog door. Some may have removable flaps that are easy to clean, while others may require more frequent maintenance such as lubrication of moving parts. Choose one that fits into your lifestyle and schedule.

Conclusion

A sliding glass door dog door can make life easier for both you and your furry friend. By considering factors such as size, material, installation process, security features, weatherproofing capabilities, and maintenance requirements, you can make an informed decision on which one is best suited for your extra large dog.
