There actually is one legitimate use for them, i.e. hog hunting. Think we might could close some of the culture gap by turning wild hogs loose in the ghettos?? I mean, that would give them the legit use for their pit bulls....
There are other animals you can use for hogs. Hounds are the traditional animal.
Except that even those dogs used for hog hunting should not be kept as "family pets". Hog Dogs are tools, and even though some can be "friendly", should NEVER be mixed with family, especially small dogs. Again - animals who's genetic purpose is to kill are not meant for a family pet, no matter how "sweet" it behaves.
