FAQs

Do I need a Single or Dual Flap Model?

Most customers select the dual flap model if the dog door leads directly to the outside or to an unheated garage. The dual flap version will provide superior insulation, while the single flap is used for very temperate climates, going from one room to another within the house or if from porches and lanais to the outside.

Remember, a dog door is an open access to the outdoors, you may be rest easier with the seal and barrier of a dual flap model.

How do I choose the right size door for my pet?

Please feel free to use the Pet Door Sizing Guide on many of our product pages. Remember that you want to select a pet door that will clear the tallest pet's shoulders by 1.5-2"...and have a low enough step over rise to allow for easy navigation given the pets breed, age and mobility now and in the future.

The sizing guide is a good starting point for determining the best size dog door for your pet. These are only recommendations; you know your pet best. Certain factors may alter these recommendations such as step-down distance to outside ground level, multiple pets using the door and wall thickness.

Do Smaller pets, like cats, have any problems using larger pet door sizes?

We have numerous customers who have multiple pets. Even the largest, Behemoth, size can be used by the household cat. You will notice that while dogs go headfirst through the doggie door flaps, cats will use their paws to gently push the corner of the flap.
