I moved my horse to a new stable near Glasgow from Edinburgh in June and she continues to have difficulty settling. When turned out, she paces incessantly back and forth along the fenceline. Otherwise she is quiet in the stable and continues to be no problem to handle and ride. This anxiety-related behaviour pretty much only manifests itself when she is in the field. I am aware that it is "searching" behaviour but unfortunately things are complicated by the fact that she has always had issues relating with other horses. Hence she has spent most of her life turned out by herself. In some cases she can be turned out with another horse if it's one or two she gets on with, but this is not an option at her current barn, as everything else there is an expensive livery and understandably they don't want to risk turning one out with her and her (selective) horse-aggression issues.
I have had this horse for ten years and have seen this behaviour before when moved to a new barn ( but not all new barns). At several stables we were able to find a field or paddock she liked and at another one, they had a pony she got on with and the owners of the yard were cool with putting the pony in a field with her. In other barns she never manifested this behaviour at all. Weird. In any case, we've tried her in nearly every field at this barn to no avail and as I said, there isn't a horse on the yard that the owner is willing to risk as her turnout buddy.
The vet is coming out to see her and give her a blood test later today. The yard owner is convinced it is a physical problem which is making the horse anxious, but I'm sceptical that this blood test or whatever tests the vet may do will show anything. I think it's a psychological issue. If I'm right (if I'm wrong, life is easier because then we can medically treat it) I am at a loss for what to do. Was wondering if anyone on this forum had any suggestions or thoughts.
