I've read a few other threads about separating herd bound horses, and most of them have ended with ' keep them separated until they get used to it' sort of thing.
Hers a bit of background: My horse has always had problems with being seperated from his chosen buddies. I can walk with him for miles without seeing a horse, and as long as he's got his halter on and i'm leading, its all good, the moment I take that halter off, he panics. I can put it back on, and he's fine. After moving to a new stables, we really saw how panicked he becomes when he isn't around his chosen horses.
He was in quarantine for two weeks. He was stalled at night, which he was fine with, on the opposite side of the aisle than the other two horses there. When outside, he could still see them from a distance, and he had 10 other horses closer to him in other paddocks. But he didn't care, he couldn't be with those 2 horses from the barn, so he panicked. For 2 weeks he didn't eat or drink outside ( which was around 8 hours of the day) and ran himself to a sweat continually. He screamed, trotted the fence line constantly and long story short, he became lame and lost A LOT of weight in that time period. The barn owner had never seen a horse like this, she was constantly concerned with him colicing, and after quarantine it took months to get him back to his previous standing, both muscle and weight wise.
Even now, if you leave him in the barn without buddies, he circles his stall, doesn't eat or drink, and all around loses his marbles.
Now, this obviously isn't healthy. I am bringing him home this summer and despite having a buddy, they won't always be able to together 24/7. How should I go about separating him without risking his health? If I was to separate him, will he eventually give up? ( he didn't give up in the time he was in quarantine so i'm skeptical)
