  • Choosing the correct size door for your pet is not difficult. Remember you can always get a door which is a little bit larger, but do not get a door which is too small. Here are some guide lines and suggestions to help. If you have more than one pet, you will need to focus on the larger dog.



    Door Sizes and Pet Weight:

    If your cat is smaller than about 15 lbs or your dog smaller than about 8 lbs, a flap size of around 5" x 7".

    If your dog is between 8 lbs and 35 lbs consider a flap size around 8" x 11".

    If your dog is between 35 lbs and 80 lbs consider a flap size around 10" x 15".

    If your dog is over 80 lbs consider a flap size of 15” x 20”.

    Exact Measurement: 1. Measure your pets width - Simply open a door the minimum width needed for the widest part of your pet to comfortably walk through, then measure the door opening and add an inch. You can also stand above your pet and use a ruler to measure the widest portion of your pet, then add an inch. It is important to add an inch or so, that way your pet will not rub on the door as you pet passes through.

    2. Determine your pets heightM – Simple measure from the top of your dogs shoulders (the withers) to the lowest point of your dogs belly or chest, then add 2 inches. It is important to add a couple of inches, that way your pet will not rub on the door as you pet passes through.
