Besides coondogs, what domestic dog breeds are popular with rednecks, hillbillies and good ol' boys?

Plotts and Catahoulas are the only two swamp hog dogs not "mutted" through crossbreeding English Fox Hounds. The Plotts an Catahoulas were bred of Spanish War dogs and hounds. Hence their independence, intelligence, and tenacity.
maremas and Pyrenees are NOT hounds. Nor are Komondor or Kuvacz.

They are Shepherds and Terriers crosses

Great Danes give the hood a bit of action every so often:

What,us worry ? Been years since we've seen an honest to God real redneck.

Pit bulls seem to be the only breed that takes to hog hunting naturally.
