When I was a child, I visited my family in North Georgia, about 1969. I was told, "bulldogs" make the best farm dogs, that loved the farm animals and would fight to the death to protect them. The breed American Bulldog actually started out as a livestock guard. Alen Scott first started selling pups in the "Game Cock Magizine" to guard chickins. But, many outcrosses of catch-dogs and other dogs have been introduced in the ABs. A number of farmers in the South still use various "unregistered" bulldogs in different regions, that have been used as long as anyone can remember. I use a breed of bulldogs known as White English Bulldog, not to be confused with the new fad white "English Bulldog." The WEB is a very old breed of bulldogs used in the Deep South for livestock protection as well as livestock retrieval when livestock is lost in the woods. At one time, cattle as well as swine were allowed to roam free. Bulldogs would round them up. This ability of WEBs to retrieve livestock, also makes them great for catching wild boar. I have used Great Pyreenes, however, they are a Flock Guard, and work without direction. Trainning them is futile. They do not come when called. Some have retained the working traits much better than others. They actually do not need to be subserviant to the livestock, but must be in control. Usually, they are indifferent when challenged by livestock, thus avoiding a battle by nonacknolgement of a fight. As for the breed, WEB, they are very trainable. First, in a litter of say 8 pups, only a couple have the so-called bulldog drives of herding/catchwork. This is, so far, the only breed I know that has both herders and livestock guards in the same breed. Most LGDs have a seperate small herding breed of dog to actually herd. www.freewebs.com/aafb
