I can see how the Saluki and Tazi would be somewhat the same thing, and Persian Greyhound is just a synonym for Saluki/Tazi, right? But the Taigan looks a bit different from them, with longer hair, more like an Afghan that's more moderately coated. And while the Taigan may be a type of Persian Greyhound, it's hard to believe it's the same thing as a Saluki :/
