Kill all dogs. Period. Track them all down and kill every one of them. The owner's pleas of "he would never bite anyone" should be ignored because that's what they all say; but we know that deep in the bowels of the beast is a prowling killer waiting to maul any child within reach.
Kill them. All of them.
Sometimes I feel the same way. I don't trust any dog. I've seen too many "gentle, harmless" dogs snap at the wrong time. When a dog is friendly and loyal it is the greatest thing, but I've seen "the nicest dog in the world" kill a kitten who had wandered too close to it's food bowl. I watched in horror as my best friend got his face lacerated by our old "harmless" St. Bernard mix. I came within inches of having my jugular severed doing a favor for a neighbor who was out of town and had to leave before his dog came back inside.
Nope, no thanks. No dogs for me. Ever!
And if anyone else's dog harms any of my family, be prepared for Biblical retribution.
You have serious issues!! I highly recommend you seek professional help.
