Named Australian Shepherd, this breed was actually developed in the United States in the 19th century. Australian Shepherds most likely hail from collies imported to California along with sheep from Australia and New Zealand, hence the name. For more than a hundred years, this breed was relatively unknown outside the livestock industry, where these dogs proved invaluable to ranchers. Only in the mid-20th century, after a rodeo performer, Jay Lister wowed the crowds with his Australian Shepherds performing various tricks, this breed became popular as pets. As of now, this breed is one of the top 15 breeds in the United States. And no wonder - Australian Shepherds are widely known for their intelligence, playfulness, and loyalty - traits perfect for companion dogs. And though Australian Shepherds are mainly bred as pets, they still have a strong instinct to herd, which they might demonstrate by herding other pets or children.
