That being said, poor Rex had to earn his place on the farm. Keri had to be sure he posed no threat to her flock. It took her about a week to back off and be more patient with him. She laid him flat many times. She never hurt him but she made it very clear with her growls and posture that she was in charge and he needed to learn the farm protocol. He has learned and I'm pleased to say they've become great buddies as evidenced by this video. It's been wet here lately so they're filthy.
