I heard dogs, if there big and vicious let them out and watch the fun of little kids getting ripped apart by some angry dogs.
Just be careful that they don't go for you, hopefully they like you if not, get a pole with a hook on the end to open the gates.
And if that doesn't work, go for a Water Gun with Oil and shoot them then get either a Molotov Cocktail or one of those Lighters that stay open and lit then throw em.
Better yet do both, just try not to get the dogs. Neighbours will be pissed that you killed there dogs although no one will care about retarded kids, not even their parents.
