So you think your the neighborhood tough guy, agitate strange dogs and then have them killed when they go after you, nice!! So now your looking into the laws so you can just shoot first and call animal control second, wow! Your a real animal lover arent you! How bout stop harassing strange dogs and go after the stupid low life scumb bag owners because truly the dog is just being an animal and i really do not believe it was a fila as you would not have been able to get away from its attack and a punch in the nose would not have stopped it, you would have been taken downtown by a true fila, sorry to say it like that but that is what the breed is bred for, protection, being a guard of its home. The price of these dogs for a true bred fila start at 1200 and go up, so if it was a young low life scumbag chances are it was a mutt that maybe resembled a fila or a poorly bred one.
Get animal control to deal with the scum owners instead , your not in Irac anymore put the attitude down and take some anger management class and learn how to deal with people, instead of intimidating strange dogs and then having them put down because you taunted them and then they chased you. And im quite sure by your first post the dog was in his yard when you approached him, wasnt he???? Cause you mention a small yard.
I wouldnt give the guy a goldfish let alone another big guardian breed!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Hes not a dog owner, responsible dog owners do not let morons like you near their dogs
