My son's house backs onto land and the farm house is at the end of a short drive off his road. There is no gate but the farmer thinks it's ok to let his two border collies run free. They often come into the street and virtually run amok in gardens etc. Previously one of his cats came home badly mauled but there was no proof it was the dogs. Today one of them got into my son's back garden and into his pet rabbit run. Luckily he got there in time and chased the dog away but the bunny is badly frightened. The police have been told about about the problem but couldn't be less interested. So, who in authority would be interested. At the minute we are struggling to stop our son from taking things into his own hands as he is seething with anger (not a happy prospect for dog or farmer TBH).
