Convenient Outdoor Access for Independent Pets

The PetSafe® Plastic Pet Door Medium allows your pet to enjoy outdoor access for potty breaks, playtime, and daily exercise without constantly relying on you to open the door.

Designed for simple DIY installation, this versatile pet door can be installed in interior or exterior wood, PVC, metal, and paneled doors. The durable white plastic frame is paintable, allowing you to customize the appearance to complement your home’s décor.

The soft, flexible transparent flap is lightweight and easy for pets to push through while remaining durable enough for everyday use. A removable snap-on closing panel allows you to temporarily restrict access when desired and helps discourage unwanted animals from entering your home.

Its versatile design also makes it a popular choice for storm doors.

Ella R. ★★★★★

My dog figured out the plastic flap in under a day, and now she lets herself out for potty breaks whenever she wants. The medium size is perfect for her, and the flap swings quietly enough that I barely hear her coming and going.
