Frequently Asked Questions

Q: What size dog can use this door?
A: This door is designed for pets weighing between 45 and 100 lbs, making it ideal for medium to large dog breeds such as Labradors, Golden Retrievers, German Shepherds, and similar sized dogs.

Q: Can I install this in an exterior door?
A: Yes — the door is designed for easy installation in both interior and exterior doors, as well as walls. The outdoor-grade polymer frame is built to handle weather exposure.

Q: How does the double magnetic flap work?
A: The two magnetic flaps create a secure seal when closed, keeping drafts, insects, and weather out. Your dog simply pushes through the flap, and it automatically closes behind them.

A: Absolutely — the reinforced heavy-duty polymer frame is specifically designed to withstand impact and daily wear from large, active dogs, unlike standard thin plastic pet doors.

Q: What is the closing panel for?
