The curs we have go back to dogs from the Okeechobee area for the last 45 years. My contacts and friends were much older than me, and have all died or lost touch.
I live in North Florida. The reason for getting dogs from down there is the people and the environment. Even though people disagree on exact traits the type of dog has stayed true for more than 100 years. The area produces a lot of tough, heat tolerant dogs, with the desire to work.
Every dog I got was a cull for trailing hogs too far or being too rough on cows.
