Getting a hognose to play dead is almost near impossible!! I think that wild ones will do it and a newly hatched cb may do it.
And yeah you would have to let a hog chew on you for a long period of time and they would have to get you between the fingers or something like that. I have fed my hogs live food and I will tell you that they chew when they eat and that mouse is still alive all the way down.......so I would say their "venom" is extremely mild. I believe probably more geared towards toads/frogs.
Here is link with a bite......please remember he let him chew on him for 3-5 min........
