content: They are 'game dogs', they were bred to be horrible killers in gambler pit fights, the mutts are such killers they even kill its own master and will attack children. A Game dog meaning you could chop one of its legs off and it would still keep going and fighting in a bloodsports arena. The best way is to land a fatal death blow, a knife can open its neck, a big shovel swung well might take its head off, a crow bar mighbt go through its ribs but YOU need to be healthy to swing like a farmer / viking or be ARMED like it is your right in America, take a gun and blow the dogs head off, im not sure about pulling the legs back, snapping its legs like chicken wings because they are 'game dogs' breed to keep going, i used to see liveleak vids and these mutts keep biting, they keep mauling keep locked on even after horrible injury, I see one where a pitt was tranquiized and still suspended in air  but the jaws were still locked on @GeneralDisposition @flaxom I wont say dont injure it, dont slap it or break its legs, but to MORE land a Killer blow, your hit should aim to kill the dog in a fatal blow, smash the skull in or go through its ribs with something sharp and into its heart. You could also tear its nutsack off, ripping its balls off that would get most dogs attention even a bloodlusted Pitt is going to feel that one. Unless you are a kickboxer with steel toe caps, @AlfonsHilter  I wouldnt waste my time kicking it in the stomach, maybe a full force kick into its throat maybe, I dont know its difficult to know if I fully seen red and wanted to kill a bloodlusted pit, if I was unarmed probably I would pick up a large rock and just bash its skull in old school cave man style. If you ever confront a pitbull never hold back, just kill it.
