not with a bark, but a dog-whistle

When a dog barks to get attention, it could be a lighthearted 'wuff' or altogether more noticeable full throated and sustained utterances.

Someone responsible for the dog has to determine whether the effect is endearing or sometimes requires discipline.

Just as important is the reason for the bark. An imminent danger maybe? or just making a noise? It doesn't matter how cute the dog looks, an owner still needs to be able to handle the situation.

So when an amoral politician uses dog technique to gain attention, there's a similar question.

A blatant use of viral populism to scrabble into the news needs a firm leader to say 'No'.

But this scruffy haired dog can't even be kept on a short leash. Its day has passed.
