SORRY! this is a NO-NO. You do NOT squirt the dog with water or do
anything which actually touches the dog! Doing so is called ASSAULT and
you may end up spending heaps of $$$ on legals.

In that case, you must complain to the council EVERY time it barks, And
keep complain about the animal barking. Either your neighbour does
something or you learn to put up with it.

Then you fall over and require medical attention as a result of nothing
being done and you then can sue both the neighbour and council. {:-).
