We have had our anti-barking device pointing over the neighbour's fence and downwards so that when the horrible little Scottie comes out at 6.15 am it should get a blast as soon as it starts yapping. Either it is a rather stupid dog or just doesn't care because it barks almost as much as before. At one stage, it seemed to be quite clever by rushing out and scampering to the far side of their garden to be out of range of the device before barking. We are unsure about whether the device works or not and after about 3 months, we expected better results. It makes us feel a bit better because we are at least trying to do something about the nuisance. We did consider buying an ultra-sonic anti-barking collar and popping it anonymously through his letter box. He certainly hasn't taken the hint and we just hope that the animal dies soon.
