It's always the hog doggers that get blamed. I remember 15 to 20 years back people hauling trailer loads of hogs all over the US and turning them loose on people's ranches... so the deer hunters could have more to hunt haha.
I get shunned when I say the exact same thing, I can remember my paw paw had a guy in Tn that would come down and buy good boars by the trailer load and he didn't own a dog of any kind, he was actually urged to do it by the fish and game dept to promote another form or hunting, if it's the sodium nitrate there's not much we can argue about it as far as toxicity to humans or other animals because we consume it daily in the foods we eat it's just lethal to hogs because they aren't biologically designed to digest lots of sodium, there will be some restrictions on its use but not a lot, just another battle that were up against....
