We're running a fun contest over on
You can win 1,000 pounds of dog food, with delivery.
Keep the food for yourself, or donate it to a rescue or shelter.
All you have to do to enter is visit: https://plexidors.com/contest-2015/ where you answer an easy question and upload a photo of your dog using a dog door.
It doesn't have to be a PlexiDor - any dog door will do.
