He is a tri coloured blue merle border collie. He does not herd sheep but I do agility with him which he loves and is very focused to the exclusion of every thing except me... His mom a Red Merle is registered with the International Sheep dog Society and has champions in the linage. Dad is a b/w BC Every other dog in our class works for titbits, but Blue is not interested, just wants to do it and he gets his rope tuggy at the end...
