It's a rare horse that is truly content to be alone; though they can learn to do it, it can be one of the hardest lessons of a horse's life. Some people start keeping horses separated, starting at an early age; though these animals may be easier for their handlers to work with without the "herd sour/buddy sour" behavior, they can be so socially inept that they don't know how to behave when they are in the company of other horses.![]()
That makes sense and sucks for the poor horse :/
