Back home in Florida, we go to the woods to "catch" hogs not to hunt them. Those white dogs have been doing just that for centuries.
Which "white dogs" have been doing it for centuries?
In Florida , our old english whites (web) in particular, which are in fact direct descendants of the Alanos(shepards mastiff/spanish alaunt cross). Not saying we use dogos in particular, but the Web's were used to build those Argentina dogs. Us "crackers" were smart enough to breed enough old english white into our lines of curs to where we did not need to carry a Bulldog.
