Saluki

The Saluki (Arabic: سلوقي) is perhaps the oldest known breed of domesticated dog. A study published in the May 21, 2004, issue of Science confirms the Saluki's antiquity through DNA analysis identifying it as one of the earliest breeds to diverge from wolves.[1] Like elsewhere in the Fertile Crescent region, Saluki-like animals appear on the ancient ceramics from Susa and Sialk of 3500 B.C.E. in Iran, as well as on Egyptian tombs of 2100 B.C.E.[2] The breed had been occasionally imported to England before 1840, however there was no serious interest until the Hon. Florence Amherst imported a breeding pair of Salukis from Lower Egypt in 1895 and began working to popularize the breed. The Kennel Club recognized Salukis in 1923.

Widely admired for its beauty, speed and endurance, the Saluki is a sighthound and historically traveled throughout the Middle East with nomadic desert tribes over an area stretching from the Sahara to the Caspian Sea. As a result, different Saluki subtypes, varying mostly in colour and coat, can be found across this widely scattered area.
