Egress and ingress

I finally got around to installing a dog door from our backyard onto the porch. Our two dogs, Willie and NellyBelle, could always go out the screen door, but they had difficulty coming back in.

Nelly (the Boston Terrier) learned to use the door quickly. It took her about a day to teach Willie, the white boxer. Willie is not the brightest bulb in the chandelier, but he makes up for it with his charming personality. He got out of obedience school with a GED.

Now, my task is to fix the other three screen doors on the porch that Willie has gone through a various times. A flimsy screen door is no match when Willie sees something on the other side that interests him.
