[00:22.54]Every time he wanted to come into the garden he would bark until someone opened the gate. [00:30.39]As the neighbours complained of the noise, my husband spent weeks training him to press his paw on the latch to let himself in. [00:41.56]Rex soon became an expert at opening the gate. [00:46.22]However, when I was going out shopping last week, I noticed him in the garden near the gate. [00:54.81]This time he was barking so that someone would let him out! [01:00.09]Since then, he has developed another bad habit. [01:05.10]As soon as he opens the gate from the outside, he comes into the garden and waits until the gate shuts. [01:14.07]Then he sits and barks until someone lets him out. [01:18.58]After this he immediately lets himself in and begins barking again. [01:26.28]Yesterday my husband removed the gate and Rex got so annoyed we have not seen him since.
