The Chow Chow dog breed (sometimes called the Chao Chao) has an appearance that makes it difficult to confuse it with another dog. Few people know, but recent studies have shown that these dogs come from Mongolia and northern China, and the breed is over 2,000 years old. At least this is evidenced by images on pottery dating from 200-260 BC. Their closest relatives are wolves. Would you like to have a Chow Chow tattoo?
