I had a flashback to our neighbor we had way back when my first dog Jo was a young dog. She was not a big barker(Lab) but she would bark when people come around the house. The neighbor to our left would complain every time she barked. One night he even called over to the house to complain about her barking and she was inside laying on the floor.

Um not our dog!
So one night, Jo wanted to go outside late one evening and she starts barking like crazy at the neighbors garage which is just along the property line. Their house is dark and we see flashlights in th garage so my dad calls the police. Seems that a pair burglars were in the garage robbing them and Jo scared them away and the police caught them a block over with a bag of tools and some other items. They had been trying to get into the house but hadn't made it in yet. Pry marks were on the backdoor.
When the neighbors found out. The wife tells her husband to quit complaining about the dog barking, she can bark all she wants. I guess when the dog saves your property are grateful.
