Yes, Grace is also a Southpaw!
Worked her today with Jen's help. She is just lovely. She is stopping on balance, is not afraid to walk in the pressure. Has no problem coming between the fence and the sheep. Has no problem peeling the sheep right off the fence. She's pretty tight on her right side ... and pretty lovely on her left.
Jaenne took some video for me, and as soon as she sends that to me, I'll post it ... well, the good parts anyway. ;-)
