Automatic & Electronic Dog Doors

An automatic dog door (also called an electronic or smart dog door) stays locked until your pet walks up wearing its collar key. Then it unlocks, lets your pet through, and locks behind them. Strays, raccoons and other animals stay out, and you don't have to get up to let the dog in or out.

Shop by where it installs

• Exterior doors: the PetSafe Electronic SmartDoor in Small (up to 15 lb) and Large (up to 100 lb).
• Sliding glass doors: electronic patio panels in single or dual pane that fit into your slider track with no cutting.
• French doors: a glass panel with a PetSafe smart door built in.
• Sash windows: single or dual pane electronic window inserts.

Things to know before you buy

• Power: most electronic doors run on batteries (the SmartDoor uses 4 D-cells), so keep spares on hand. A low-battery light warns you when it's time.
• Keys: each pet wears a small key on its collar. Program extra keys for multi-pet homes.
• Size: measure your pet's shoulder height and width, then pick a flap at least 1–2" larger.
