What size dog door should I get?

Pet sizes – and pet door sizes – can seem confusing, because it’s relative to a person’s frame of reference. If a person is used to Rottweilers, a Beagle looks like a small dog. To a person used to teacup Yorkshire terriers, the Beagle is pretty big.

To make this more confusing, the right size pet door often looks small compared to the pet. Dogs tend to duck their heads and lift their feet when they go through, so the opening doesn’t have to be as tall as the pet. If you have larger and smaller pets together, the PlexiDor opens so easily that a smaller pet can generally use a larger pet door.

The weights in the list below are guidelines. If your pet is right on the spot you might need to measure him or her and compare with the opening size. Or, contact our customer service. They are experienced and happy to help.
