I don't know a huge amount about Arabians, but this is what I've heard, and what I do know. There are Egyptian Arabians, Russian Arabians, Cabberet (sp?) Arabians, and probably more strains that I haven't heard of before. From what I've heard, I believe that the Cabberet Arabians are more sport horse type, versus racing, or saddleseat. Egyptian Arabians have very typey heads, and are finer boned I believe. And are generally more of the race type strain. And Russian Arabians, are a bit thicker, and don't have as typey of a head. Do please correct me if I'm wrong though, as I got this all from a breeder who has kept the mindset of what the arabs were in the 60's. I have a Cabberet bred Arabian, who is bred to be more of a sport horse type Arab.
