Review on 🐾 Endura Flap Pet Door: Double Flap, Extra Insulated, All-Weather Doggie Door with Energy Efficiency - Ideal for Small to XL Dogs - Available in Black, Tan, and White Frames - Well-Built with Locking Cover by Elisa Suggs

We have a high 90# Weim; it happens with a margin. It took him a few days to get used to the door and a few more days to risk stepping in, but now he bursts in without a second thought. We live in the Houston, Texas area, it's hot and humid and mosquitoes abound. We've been paying close attention: hot and cold air doesn't come through this door when it's closed, and it closes fast enough that the bugs can't seem to get in. The cost of this door was more than we wanted to spend, but the positive reviews and guarantees convinced us and we were not disappointed! Light transmission is good too, letting in some extra light.
