I've heard of Musk Ox, but Musk hogs?
I thought Arkansas had its own wild hogs.
As for the four-legged ones, they're actually feral hogs – descendents of early livestock that went wild.
Sometimes they're called Javelina, Tayaussa or Musk hogs.
Some herds of cattle and horses run wild; but these were, of course, introduced, as were also the wild hogs, the numerous rabbits and the less common hares.
