Our dog, Rex, used to sit outside our
front gate and bark. Every time he wanted
to come into the garden he would bark
until someone opened the gate. As the
neighbours complained of the noise, my
husband spent weeks training him to
press his paw on the latch to let himself
in. Rex soon became an expert at opening
the gate. However, when I was going out
shopping last week, I noticed him in the
garden near the gate. This time he was
barking so that someone would let him
out ! Since then, he has developed another
bad habit. As soon as he opens the gate
from the outside, he comes into the gar-
den and waits until the gate shuts. Then
he sits and barks until someone lets him out. After this he immediately lets himself
in and begins barking again. Yesterday my husband removed the gate and Rex
got so annoyed we have not seen him since.
