I am having the same problem now with my new goat who has become incredibly too co-dependent, when I have him high-lined next to my other wether and I walk away he flips out, screams and bolts to the end of the lead and tries to follow, he even broke a collar! And now his behavior has rubbed off on my mellow Saanen. I don't know what to do, I am up visiting my family in Oregon and I literally have to sleep outside with them so they don't keep the neighborhood up. He's fine the moment I walk out the door. I wonder if I should just leave them until they stop crying, like for hours and hours? We just got back from camping for 5 days and they loved it, they were mostly not tied and had lots of meadows, We hiked to the top of a mountain and they did great.
