PPal - (your name would imply you know something about this then!) are you talking about javalinas? They're very very small. I haven't seen one in the wild since I was a child (early 80s) when, one Thanksgiving, my father & I went rabbit hunting. We got 3 jacks (had to discard each as they were completely infected with worms), and startled a nest (?) of javalinas (about 3-5 of them.. quite small, about the size of a cocker spaniel, which is pretty tiny compared to a regular piggie.. we raised 4 pigs when I was a teenager (2 neutered boars one year, a neutered boar & a sow three years later) and the javalinas were a breath bigger than the 8 week old piglets we'd brought home.)
