Funny you mention that. This is actually a Florida Cracker breed that was brought to America by Ponce de Leon in the 1500's. He was attacked and driven out of Florida by Indians, He left his horses, cattle and hogs and fled to his ship, then sailed to Cuba where he died.
After the Spanish left, their cattle, horses and hogs went into the swamps and bred there for 100's of years. Wild. Florida pioneers would go into the swamps to "catch the cattle". The breed was saved in the late 1940's and has a strong presence today in the state. There is an organization devoted to raising and breeding the cattle to keep the breed pure..

Here are some cowboys "catching" cattle. The dogs play a very important role in getting these cattle out of the swamps
