PetSafe Wall Entry Pet Door with Telescoping Tunnel
Fitted with a telescoping tunnel, the PetSafe Wall Entry Pet Door is one of the most popular electronic dog doors around. This system alongside a double flap door design makes for an excellent insulation mechanism. It makes this electronic door energy efficient as it keeps out the weather.
The door itself is made from aluminum frames making it a durable one. You can install it into walls of a thickness of 4.75 to 7.25 inches. What makes this possible is the telescopic nature of the plastic tunnel. You can do the installation yourself too.

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.
