cause was related to cardiac conditions, including heart failure and unspecified heart defects. Cardiomyopathy, heart murmur, and other cardiac issues were present in 17.2% of responses while dermatolic conditions such as dermatitis or alopecia were reported by 10.8% of responses. Old age is listed as the third most frequent cause of death. Hip dysplasia is uncommon in Salukis, with the breed ranking joint lowest in a survey by the British Veterinary Association in 2003. The breed scored an average of 5 points, with a score of 0 being low, while 106 is high. History The Saluki's ancestors were historically bred in the Fertile Crescent, where agriculture originated. Images of running dogs with long, narrow bodies adorn pottery found in Susa, southwest Iran that dates back to 6,000 years ago, despite the depictions bearing erect, pointed ears. Dogs looking similar to Salukis are shown on wall carvings of the Sumerian empire (now Iraq), dating from 6,000 to 7,000 BC. The ancient skeletal remains of a dog identified as being of the greyhound/saluki form was excavated at Tell Brak in modern Syria, and dated to approximately 4,000 years before present. Dogs that look similar to Salukis and Greyhounds were increasingly depicted on Egyptian tombs from the Middle Kingdom (2134 BC–1785 AD) onward, however it was during the Eighteenth dynasty of Egypt that Saluki-like dogs rose to prominence, replacing hunting dogs called tesem (thought to be similar to modern pariah dogs or a generic term for a dog) in ancient Egyptian art. The variety spread southward into the Sudan. From Iran, such dogs are mentioned in the poetry of Khaghani (1121–1190), depicted in miniature paintings of hunting scenes along with horseback archers by Master Kamāl ud-Dīn Behzād (1450–1535), depicted in book illustrations by 'Abd al-Wahhab ibn 'Abd al-Fattah ibn 'Ali (1516). The Silk Road was a trading route that stretched from ancient Iran to China. Examples of dogs that look like Salukis were painted by the Chinese, fifth Ming Emperor Zhū Zhānjī, known more commonly as the Xuande Emperor during the Ming Dynasty (1368–1644). The inscription on the painting reads "playfully painted [by the] imperial brush" in 1427; additional red seals were added in later years by owners of the painting, which also reveals that the painting was in the Imperial Chinese collection in the 18th century. Other earlier artifacts place similar Saluki-like dogs further back in Chinese history to the 7th Century
