"Oh no, it looks like that dog is being abused, we need to get Police and Animal Services to arrest and charge the owner and take the animal to a shelter [where it can be euthanized]" is what would likely happen in a municipality where guard dogs are put down when they bite thieves on private property with all of the mitigating factors for the dog (the dog was chained up, and could not escape, and it was in the middle of the night) and all of the aggravating factors for the thief (the area was well-secured, signed and alarmed, they could not have entered by mistake, and it was in the middle of the night).
