Hi there. I have a neighbour who has placed numerous signs in her front yard telling passing traffic that my dog makes "blood curdling crying" noises day and night. Funnily we have never heard this alleged noise. We are both animals lovers and would take action immediately if we thought our dog was in any distress. Her signs identify our home address and encourage people to complain to the RSPCA and make derogatory comments about us being irresponsible, etc. We have tried to discuss this with her which resulted in another sign telling everyone people from our address are not to enter her land Anything we can do to stop her shenanigans? She is a serial complainant.
