...when he wants to come in. The door is half aluminum on the bottom and half glass on top. I've been bragging over the past few months about how great he has been but this is one thing we can't get him to stop doing. He literally throws himself at the door and then jumps up and down looking in. The door is only 2 years old from when we renovated and there is no way we will replace it. We took the screen and glass off of the bottom and put the aluminum panel back on the bottom for his safety. I can't correct him from outside because he never does it if we are out there. He's not outside too much but it makes such a frightful crash when he does run into it. He's ruining the siding on the house next to the door and it is really loud. He even does it if he's outside for only a few seconds..any advice would be greatly appreciated.
