The world's oldest known breed of domesticated dog is the saluki, believed to have emerged in 329 BC. Saluki dogs were revered in ancient Egypt, being kept as royal pets and being mummified after death.  There are carvings found in Sumer (present-day southern Iraq) which represent a dog, closely resembling a saluki, which date back to 7000 BC.
