Wolves were almost hunted to extinction.

It's Thor's Outdoor Thorsday!

Wolves were also nearly hunted to extinction in the Great Plains at the same time buffalo were. The guys that hunted them called ‘wolfers’ used some pretty immoral tactics, they would shoot and cripple a bison and inject strychnine poison into their arteries so it would make the whole carcass poisonous and then wait for wolves to eat the meat and die. Thanks to Steven Rinella and American Buffalo.
