Ideal Cat & Dog Doors are strong, durable, and easy to install. If you are looking for a doggy door for your sliding glass doors check out Ideal Fast-Fit models. They have a spring-loaded design that makes them super easy to install or to remove in mere minutes. They also offer an optional Key-Lock Kit that will work with the existing lock on your sliders - a very rare feature.
We have a large selection of Ideal Doggy Door models to meet your needs including pet doors for walls, for doors, for sliding glass doors and for windows.
Important: Ideal Pet Products is one of very few dog door manufacturers that make models to fit vinyl sliding glass doors - Pella and Andersen doors for example. See Ideal VIP Vinyl Patio Pet Doors.
