History of the Southern Cur Dog
The "cur" dog is one of the few working breeds that originates right here in the United States. They come from different lines, and of different types. While all have a common origination from the southern part of the US, they have similar but distinctively different hunting styles, traits, and separate regional originations. Most of the breeds of cur dogs date back to pioneer times, and were used to help put food on the families table, as well as to be a guardian to alert their families to the approach of strangers. the worth of a good hunting dog back then should not be underestimated. A families Cur dogs played a huge role in producing game for the family food, both hunting and rounding up semi-wild livestock that were "free ranging". A dogs working ability was of paramount importance. A dog had to provide above and beyond what he cost his family in feed. There are many short references to this type of dog in American literature but the exact history and make up of most of these "Cur Dogs" is vague due to the fact that most of it is verbal, and was not recorded on paper...
