Doggy Door Purchase Considerations

Before deciding on a doggy door that is right for your large dog, it’s important to consider the following;

  • The size of your dog – be sure to measure your dog before ordering to ensure they’ll be able to fit through the flap comfortably, and always observe manufacturer weight limits for the doggy door you are considering.
  • Climate and energy-efficiency – doggy doors with double flaps tend to be more suited to extreme climates and weather conditions, they’re also more energy efficient. While single-flap doors tend to be more suited to moderate climates but are also more affordable. 
  • Budget/Style – while plastic dog door options are more affordable they don’t tend to offer as many color variants as aluminum alternatives. Similarly, they aren’t as ‘heavy-duty’.
  • Mount type/permanancy and ease of install – there are doggy door options to suit a multitude of openings, including traditional (more permanent) door mount and wall mount options, versus sliding door options that are slightly easier to install and more renter-friendly.
  • Door/wall thickness – make sure you double-check the thickness of the wall/door you intend on using (and height for sliding doors) as these vary wildly between suppliers and not all manufacturers offer telescopic/tunnels for increased doggy door depth.
  • Availability of replacement flaps/parts – anyone that has had a doggy door before knows that they cop a beating from your dog/s! Replacement flaps are especially handy if you plan on keeping your doggy door for a long time or if multiple pets will be using the door.
