Navajo Churro

Sheep

The Navajo-Churro, or Churro for short, is a breed of domestic sheep originating with the Spanish Churra sheep obtained by the Navajo Indian tribe. The breed is renowned for its hardiness and adaptability to extremes of climate. Its wool consists of a protective topcoat and soft undercoat. Some rams have four fully developed horns, a trait shared with few other breeds in the world. This breed, also known as the American or Navajo Four-Horned sheep, is raised primarily for wool.
