The Herald Tribune recently reported on PlexiDor Pet Doors. The paper tells the history of the company and the doors, mentioning the special K9 Composite panels specifically designed to be sturdy and seal weather out.
The article also quotes Barbara Cook who houses six Weimaraner show dogs. “I would have never put in a door if I hadn’t seen this one,” she said. “It gets a lot of use, that’s for sure.”
