Rarest and MET, a true koochi dog bred by Koochi nomads in Afghanistan. I have also met several Iraqi landrace LGDs, herders and mixes of the two. I have met Okinawa Inu. Viequensie dogs (pariah type native to Vieques Island). American Staghounds in Iowa. I've met every kind of tree hound and most foxhounds in america. Met the major cur breeds, blackmouth, mountain, catahoula, even a couple of lacy dogs and some less well known like parker cur and outlaw cur.
And I have SEEN what looked like Bucovina dogs in Romania, saw Tosas matched in Japan.
not sure what else, now i have to sit and think about it.
