Made from high quality aluminum to ensure a lasting solution, our large aluminum 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.


The high quality aluminum construction provides a more durable solution than plastic dog doors. These pet doors are recommended for indoor applications or outdoor access to covered areas, as well as outdoor applications for temperate climates.


Havahart® aluminum pet doors are suited for frequent use and high-energy dogs.



Our aluminum pet doors accommodate door widths from 1.25" to 2.25".


The large aluminum 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.

Ordered this to replace the door which was ripped out by an animal exterior to those that live in the barn (I think it was a racoon, either very hungry or possibly on 'steroids'). Any rate - door was an easy and uncomplicated install, solid construction and works well to secure the barn. I very much like that the frame is metal, the pass through flap is thick plastic AND the security door has a 'pull knob' that allows you to not only close the door to traffic, it allows the door to be SECURED. Works well for cats and the barn - Great product.

Easy to install and works great! We have a mix of small pups (chihuahuas) and spaniels. They all have easy entry and exit. They range in size from 3 pounds to 60. Not a problem for all.

I've owned other pet doors, with the plastic frame and plastic locking panel. As my yellow lab grew larger he started jumping on it with his front paws and popping the panel out of its grooves and entering the house when he wasn't supposed to. This Havahart aluminum pet door solved my issue. It comes with a steel locking panel and an aluminum frame. No dog can pop this one open. The door has a white finish and was very easy to install in the previous door cut-out I had. It is a quality door that I would highly recommend for people with larger dogs.

I had never heard of this brand before. I purposely ordered an aluminum door because 1) it was going in a metal door; 2) the cold weather, etc., is hard on plastic .. period!! The door was easily installed, even without decent directions. There was one screw missing.. but 3 out of 4 still managed to ensure a good seal. The price was decent, compared to the other available products. The time it took to receive the product was very good. (And the fact the S&H was free made a huge difference in the total purchase price!!) I thought I was getting one with 2 flaps, but that was probably my mistake. I do like the fact it has a metal fitting to slide into the opening and fasten securely, ensuring no one comes in uninvited!! I got a LG because I have a 70 lb border collie mix. The size is just right.

This item has worked out very well for our family. We can go out for the day and don't have to rush home to let the dog out. It only took our dog about three days to get used to it. My only complaint is that it is not air tight. I think it would be more energy efficient with a different door design. We are going to try putting thin weather stripping around the frame. I'm not sure there is enough clearance to do it but we have to try something. I am concerned about heat loss and drafts, as that is the room our dog sleeps in.
