PetSafe Extreme Weather Energy Efficient Pet Door, Unique 3 Flap System, White, for Dogs and Cats
To increase the energy efficiency, the PetSafe Extreme Weather Pet Door has a system of 3 flaps. It is a design that is more energy efficient than a single flap pet door. Therefore, if you live in an area prone to extreme weather, then this could be a great addition to your pet.
Of the three flaps, the one at the center acts as an insulation for temperature control. It either keeps warm or cool inside your home, depending on whether it is hot or cold outside. The door is best used by dogs with a maximum weight of 100 pounds.

Hi! I’m Karen and a certified dog lover. As a freelance writer and blogger, I do my best to squeeze in some time with my dogs, learning more about the way they act and how I can make sure that they continue to stay well-cared for by yours truly.
My dogs have helped me through a lot, and this is my way of giving back to them! Besides animals, I also love to travel and cook, having explored my country’s restaurants and unique places. Follow me as I show you all the amazing tips and bits of information I learn along the way about our furry friends!
