 The breed bears similarities to the Border Collie and Rough Collie breeds that arrived with European settlers in the 19th and 20th century to herd farm animals such as cattle, horses, and sheep.The Border Collie likely arrived in the municipality of Uruguaiana in Rio Grande do Sul in the 1950s, along with a herd of Australian Merino sheep.Subsequently, these dogs were introduced in Pelotas city.
