All of our houses come standard with a vinyl flap door installed but due to the tremendous climate swings across the nation, we have been asked to offer an optional upgrade door system to seal the living compartment even better. We researched every dog door manufacturer extensively.comparing quality, warranties, draft analysis, pet security, and door size availability. After careful consideration we have chosen Pet Doors USA, Inc. with their Five Star Plexidor to be the optional upgrade door for our western cedar doghouse.  If you live in an area where summers are excessively hot or winters are extremely cold and your doghouse is insulated, then you need to seriously consider an upgrade Plexidor. Wind gusts and blowing rain or snow can not break the seal on the Plexidor If you are considering a PetCool heat and air conditioner/dehumidifier, the Plexidor needs to be a serious consideration. The PetCool unit will run more efficiently and the savings in electrical usage will pay for the Plexidor in just a couple of years. These doors open and close with a gentle push, they are quiet and most important, they are edged with a nylon pile weather seal to provide superior draft proofing. The doors are made of rigid high impact, shatter resistant plexiglass, set in an anodized heavy duty aluminum frame structure. In the past five years, seeFIDO has had an increasing request for outer security doors to protect pets from predators (coyotes, wild dogs, even people). Our Plexidors come with a predator key lock so that you can secure your pet at night from nocturnal predators. All sizes have the predator key lock except the small door which does have a manual latch knob (no key). Best of all, when you upgrade to the Plexidor, your doghouse arrives with the door already installed, saving you the trouble and expense of putting it in later. Door opening size with plexidor is 16" wide x 23 3/4" high, and is raised off the floor 7" to accommodate taller breeds. View all Dog Houses |
