Call the cops; the dog is a nuisance. If the cops get involved, it becomes their nuisance also.
Feed the dog ground beef laced with valium/quaaludes/laxative; just maybe the owners will get the message that it could have just as easily been poison. Take video and get statements from other neighbors. Don't break the law until the law fails you. Until it's resolved, Meesha's parents might just have to meet her at the bus after school.
It's too bad the owners can't be euthanized.
"Right is right, even if no one is doing it; wrong is wrong, even if everyone is doing it." - St. Augustine
