I've seen the next door neighbours let their dog out to do it's business in a field that belongs to my partner's family. His relations grow maize in the field which is later to be consumed by cows. The neighbours are too lazy to walk their dog even though there are plenty of them to take it in turns to walk the dog. We've asked them not to go into the field a while ago. Should I tell the owners about what is happening? The neighbours are the type to retaliate and threaten us.
