The PetSafe Doggy Door for sliding glass doors is a smart choice for pet owners with medium dogs (up to 40 pounds) who want an easy, no-cut installation. Its adjustable height (about 75 7/8" to 81") lets it fit various sliding door tracks, making it suitable for apartment dwellers or renters who don’t want to damage their doors.

Another handy feature is the closing panel, which lets you control when your pet can go outside—ideal for managing outdoor time.

This dog door is designed specifically for medium-sized dogs, so it won’t work well for larger breeds.

This door stands out for its energy-efficient design: the flap seals tightly with magnets, helping keep your home insulated and reducing energy costs year-round.
