I think you are making a big mistake about not reporting it. You think it will accomplish nothing, and it may not, but you will have created a paper trail that might be vital later on. I don't know the legal environment around there, but if you are in one of those over-regulated places around a city, you really should have that paper trail.
Where I live there is no animal control. If you call the police about something like this, they would laugh at you, and just say "do what you have to do".
We take care of these issues ourselves. If the dog is running lose and is acting aggressive to people or livestock, it is shot. It is not the dogs fault, it is the owners fault, but the fact remains, the dog is dead.
I love dogs and hate to do it, but I have and will again, if necessary.
