Hogs are concidered a nucience animal, basically a pest. In Illinois Coyotes and Ground hogs are nucience animals were can hunt them all year with any weapon we choose. We can't use dogs to hunt coyotes but we can use terriers on ground hogs. Javelina are concidered game animals. Game animals are regulated by each state & sometimes the Federal government. They can onlly be hunted in season with weapons approved by the state. Each state is differant but, most classify animals as game or nucience. Javelinas & hogs both are "pack" animals. Javelinas however, have a much stronger bond with their family members and are much more dangerous to hunt with dogs vs. hogs.
