I have been a horse owner most of my life. I am ashamed to say I don't have good advice for a relative that just lost a new horse. They had just taken ownership and put the mare in the pasture. Some neighbors were firing gunshots and the horse apparently spooked, jumped the fence and ran away. She had just been hauled about 10 miles from her former home. Since she is unfamilar with the new home I am sure she will not try to find her way back there. Is it likely she will try to go to her former home or will she wander? Any advice is appreciated.
