How to measure your Ideal Pet

To determine the correct size door, simply measure the width (A) and height (B) of your pet.

(A) Measure the widest point of your pet's shoulder.

(B) Measure from the top of your pet's back (just behind their head) to the bottom of chest.

Pet door models have different size openings. Just make sure your new pet door's opening is both wider and taller than your pet's measurements to ensure they can comfortably pass through.

    Perfect fit

    Posted by Brett on 12th Jun 2023

    Ordered a new flap for a pet door that was close to 9 years old that my Heeler had been blasting thru about 97 times a day. New flap showed up on time and was a perfect fit. 10/10 will order again when needed

    Great Dog Door

    Posted by CAROL KANE on 27th Feb 2023

    We finally had to replace our plastic Ideal Pet Dog Door (medium) which we bought 22 years ago. We have only replaced the plastic liner once during that time because we couldn't get it clean anymore. It has held up very well. It finally broke at one of the screws so time to replace. I highly recommend it. The new one fit just perfectly in the current holes.

    Cats love it!

    Quality product. Check dimensions on part before using template to cut hole. Note to MFR: Screws are VERY hard to get in. Resize. Also, the sliding door not being able to stay on main part is an inconvenience. I could help design that better. Its what I do. Thank you.

    Best made pet door

    Posted by Rick Gutierrez on 20th Dec 2022

    We have enjoyed the quality, style and security of this pet door for over 25 years. I highly recommend the door for a small pet. We have used the 7 inch for many of our past pets. Installation is quite easy with some careful planning.

    Dog door

    Works great. This is a replacement. Kind of hard to make a dog door that is bloodhound proof.

    Great doggie door

    Posted by Unknown on 12th Jun 2022

    We had a medium size Ideal Pet door for our two smaller dogs for years and loved it. We acquired a Belgian Malinois and had to step up to an extra large door. These doors work perfect for our home and our dogs.

    Replacement for older door

    Posted by James G Bryan on 16th May 2022

    I replaced an older door that was about 30 years old. Nice product and I didn't have any issues. The dimensions for the door were a little different, but installation was still pretty easy.
