the turning and mauling people is not logical. it doesn't matter what the dog is. if its trained to act crazy its going to act crazy. if you teach a dog to sick on people when it gets loose and bites you shouldn't blame the dog in the news but the do. but involuntary muscle spasm in the jaws , that's locgical.
What is involuntary about a dog staying in hold?
Do you have any scientific research that backs up this involuntary muscle spasm?
I'm getting a headache here. Were you not originally talking about a very much LIVE dog catching a hog that you were describing as having "lock jaw?"
Now we're discussing a dog dying while in hold? There's also a term old timers use for dogs dying while in hold, and it darn sure isn't "lock jaw."
