We have been using the large size Plexidoor for about 15 years and love it. Our dogs are quite large, so we are upgrading to an extra larger size.
The Best Pet DoorMost pets hate flap doors! PlexiDor Pet Doors are long-lasting and beloved alternatives.
They have hinges, like a door, so there's no loud flap slap or flexible materials. They lock easily, and most models come with a steel security plate for additional security when you are away.
