Provoking dog to bark

This isn't a family law court question.  My friend has recently built in a small country town estate.  She has been having problems with her neighbours since building commenced.  More recently the neighbour is taking her dog to the back of my friends house to make her dog bark and then films my friends dog barking.  The land the lady is on is not her land and is not public land.  There are several vacant blocks on the other side of this neighbour that she could take her dog to however she refuses.  She will not speak with my girlfriend and even engaged a solicitor in relation to the dividing fence rather than speak with my friend, what had made several attempts to have amicable discussions with her in regards to it.  

What avenues does she have?  It doesn't fall under peace and good behaviour.
