Not sure which size to choose? The Porch Potty Dog Door comes in three flap sizes to suit different breeds and lifestyles
Before you order
Choose your flap size to suit your dog, and check your sliding door measurements.
Absolutely! The Slide-In Dog Door is designed for non-destructive installation, making it ideal for renters or temporary setups. You can remove it anytime without damaging your door.
Yes. The durable single flap combined with custom weather stripping helps maintain your indoor temperature, blocking drafts and reducing energy loss.
Every Slide-In Dog Door includes a removable security plate you can slide into place when you don’t want your pet using the door or when you’re away.
Each package contains the dog door panel in three sections, weather stripping, a security plate, and a complete hardware kit for easy installation.
The size refers to the flap opening, not the overall height of the panel. All sizes (Small, Medium, and Large) fit the same adjustable sliding door height range. Choose your size based on your dog’s breed and shoulder height for the best fit.
Use your dog’s breed as a guide when choosing a size. Small: Best for Yorkies, Dachshunds, and Chihuahuas. Medium: Great for Corgis, French Bulldogs, and Beagles. Large: Perfect for Labradors, Golden Retrievers, and similar-sized dogs. If your dog is still growing or between sizes, we recommend sizing up for extra comfort
