My dog, Rex, used to sit outside the gate and bark. Whenever it thought of coming to the garden, it barked and barked until someone opened the door. Since the neighbors are very uncomfortable with dog barking, my husband and I spent a few weeks training him to press the latch with his paws and put himself in. Rex quickly became an expert at opening the door. However, when I was about to go shopping last week, I found it was staying in the garden by the door. This time it called for people to let it out! Since then, it has developed another bad habit. As soon as it opened the door from the outside, it walked into the garden and waited for the door to close automatically. After that, it barked and barked until someone came to let it go. After going out, it immediately put itself in again, and then started calling again. Yesterday, my husband removed the door, and Rex was very angry, and we have never seen it since.
