Give your dog the freedom he deserves and give yourself the security you expect with our large plastic dog door.

Made from high quality plastic to ensure a lasting solution, our large plastic dog door fits hollow and solid doors. The flexible PVC flap includes a magnetic energy seal to reduce temperature loss from your dog entering and exiting the pet door.


These pet doors are recommended for indoor applications or outdoor access to covered areas, as well as outdoor applications for temperate climates.


Havahart® plastic pet doors are suited for low to medium usage indoor and outdoor. If you have a high-energy dog or need something for heavy usage, consider our Havahart® Large Aluminum Dog Door



Our plastic dog doors accommodate door widths from 7/8” to 2.25”.


The large plastic dog door measures 11.5” x 17.5” and accommodates breeds up to 100lbs.
Additional pet door sizes ranging from small to extra large are also available


How to Measure Your Dog for the Correct Size Door:

  1. Height: Measure your dog from the floor to the highest point of the shoulders. The flaps of the dog door should be at least 2 inches above the top of your dog's shoulders.
  2. Width: Measure your dog at the widest point and add an additional 1-2 inches to be safe. Remember: If your dog is a puppy or is going to continue to grow, please take that into account when measuring. Also take into account the amount and length of your dog's hair. The width of your dog may be smaller than you measure if your dog has long hair.


Additional Points to Consider When Choosing the Correct Size Dog Door


Ensure the dog door is low enough for your dog to step into. Having the door too high could make it difficult for your dog to step through. Also take into account the age of your dog, as older dogs might have an issue raising their legs high enough to get through the door.
If you have more than one dog, ensure the door you choose will work for both dogs.
Your pet is going to use the pet door from both sides, so ensure that the height of the dog door works from both sides.



Installation can be completed in 3 easy steps and your pet door comes with step-by-step instructions. Lockable steel security panel is also included for added security.

great dogie door - the dogs love it and so do I!

  Amazon Review 

It is perfect for the home or even an apartment to separate the back area or service area inside the house. In the cold is very nice not having to leave the door open for the dogs come out to pee or drink water.

  Amazon Review 

This is as pictured, installs easily and works well. Wind does not blow it open easily. It is a good buy.

  Amazon Review 

We have our cat room set up in our garage. They love going in at out at their own ease and we can finally keep our garage door shut. Easy install too.

  Amazon Review 

Second doggy door like this. Very durable. Works great. Would recommend to others. Ships and received promptly. No complaints. Currently still using.

  Amazon Review 

a friend installed this for me, and there was one problem with one of the screws - the threads did not fit, and my friend had to improvise to make it work. Once installed, it's excellent and definitely worth the price.

  Amazon Review 

I like it. this is my second one. 1st still in door, " Little worse for wear" but have had over 3 years.

  Amazon Review 

Good product at a reasonable price. Works great! Does not close at tight as I had hoped. Easy to install, but had to make own templet.

  Amazon Review 

We needed a door for our cats, and thankfully it was for an interior door, so we didn't need the weather flap. This wouldn't work too well as an indoor/outdoor for cats, because the weather flap is very heavy. We simply removed the flap, and just have the opening for the cats. It comes with a metal cover, so if we need to cover the cat door and keep the cats either in or out it's quite easy to do.
