One suggested origin of the breed's name is ancient Sumerian salu-ki translating to 'plunge-earth'. However, there is no evidence a breed existed then or was referred to by the Sumerians with this name, nor is it certain what 'plunge  earth' might have meant in reference to dogs. It is suggestive of digging for burrowing prey animals, but there is also a story see below) of dogs being thrown toward quarry animals by a camel-mounted hunter. The modern Saluki has retained qualities of hunting hounds and may seem reserved to strangers. Early socialisation will help prevent timidity and shyness in later life. Given its hunting instincts, the dog is prone to chasing moving objects, such as cats, birds, squirrels, and bugs.
