So are they immune to the venom or what?
Dogs and other wildlife get bit and they don't die a lot of the time. A hog is thick skinned with long hair and hard head. So They might get struck but not going to really effect them as much I would think.
Plus, venomous snakes do not inject venom every time they strike, and animals, like people, can learn to catch to a snake without getting bit "most of the time".
I am not going to take any chances on getting bit and rely on the venom not being bit/injeted "most of the time". I will let someone else be that guinea pig.
I am not saying that you should, but luckily, for folks who do get bit, there is a chance.
According to the Texas Department of Health,
7,000 people bitten by poisonous snakes annually in the USA.
0.2% of he cases are fatal
~50% are dry bites
~1-2 people die in Texas every year from snake bites.
I wish they provided some morbidity statistics as well.
While hogs don't have the benefit of antivenom or doctors, I would imagine they are more robust in withstanding a venomation than humans.
