Explain Animals on Instagram: "The Xoloitzcuintli, also called the Mexican Hairless Dog, is one of the oldest and rarest dog breeds in the world. Dating back at least 3,000 years, they were considered sacred by ancient civilizations like the Aztecs, who believed the dogs could guide souls to the afterlife. Xolos are known for their intelligence, loyalty, and calm temperament. They come in hairless and coated varieties and are prized for their unique appearance and close bond with humans."
