Energy Efficient Dog Door
Winter is coming and I have four dogs and two cats. We installed a dog door to the outside some time ago, but it's a big air leak. Even though we replace the door every six months, it's only plastic with magnets on the edges, and doesn't always fall back into place. I've tried various solutions, but what I really need is a solid door that locks into place, or a door that opens and closes with a trigger. Automatic dog doors cost about $350.00 - $450.00, and require the dog wears a special collar. I'm not looking for security, I'm looking for energy efficiency. Can someone please help? I know there are lots of others in the same position.
