Old Indo Iranian Alans tribes, living originally in the caucasian stepes, lived mainly in Extremadora Spain, and Portugal, some in central and northern Spain, up to the Goths invasion to Spain, then were pushed to North Africa and end his days in Sardinia, Corcega and balearic islands, where you can find interesting dog breeds.
Currently in this days, the Old Alans that remains in the Caucasus live in Alania, North Oscetia. I don´t know if they keep hounds like the alanos, but for shure they have Shepherd Dogs, as flocks guardians.
Oscetian Girls, descenant of the old Alanos.
