However, some dogs can be seen as dangerous, compounded perhaps by aggressive behaviour. In this instance it might be necessary to call the Police should this be the case. Barking too can be a nuisance and if persistent can affect ones quality of life. If this is the case, firstly contact the individuals responsible to reach an agreement about what to do about it. Secondly contact Housing Management or OST and finally if not content with the outcome, contact your local Environmental Health officer
