Our new horse, Sonny, is in a 2 acre pasture by himself. It's in our backyard so he sees a lot of us, but not constantly. There are two horses in a large pasture across the street (about 50' away) and they spend some time at the fence "talking" to Sonny occasionally. My question: are these horses sufficient company for Sonny? What are symptoms of a lonely horse? Sonny seems perfectly fine now, but we've only had him a couple of weeks. He's a 7 yr old gaited saddle horse with a calm demeanor.
FWIW, Sonny was not the dominant horse in his previous herd.
