so far this week I've gotten up to my back door being wide open almost every morning. It seems that Tucker has learned to open the door.....he usually wants out about 4 or 5 and I let him out and then go back to bed for a bit. When I get up around 7 or so he is back in and the door is wide open. I've also caught him with his mouth on the knob trying to go out. Our backyard is completely fenced and so is the deck so I'm not worried about the door being open...like I would be if it was the front door. It just lets bugs and flies in which is annoying...oh and the cats. I don't want the cats messing in the house. They are the reason we haven't made a dog door before now. Its a good thing I love him! Last night he was so cute. He was hot and we had the ac on in the bedroom. He went behind my "design wall " curtain (where it was the coldest) and laid down but made sure his head was sticking out so he could watch me!
