Saluki
The Saluki is the strongest case among the sighthounds. Bedouin and Persian hunters ran these dogs after gazelle and hare for centuries, and genetic studies group the breed with the Afghan Hound in a Middle Eastern branch, well apart from the Greyhound, which looks similar but sits with the modern European breeds. Claims that carvings several thousand years old show Salukis rest on resemblance alone, so treat them as possible rather than proven.
