But what happens when the horse is removed from the herd? Separating a horse from its companions for veterinary care, hoof trimming, or training is likely more distressing for group living than for individually stabled horses. The distress might also be more severe when the procedure is painful or unpleasant.

To see how horses would respond behaviorally and physiologically to social isolation and mild pain, the researchers first placed each horse in a turnout next to a familiar herdmate, with visual, olfactory (scent), and tactile contact over a fence
