I've always wondered if a horse could feel shame, embarrassment, envy, love, hate, etc. I've been reading a bio on seabiscuit, and they said that He could ruin another horse's confidence and the horse would seem to be embarrassed after it lost. And Seabiscuit would tease them as he passed, and would be 'ashamed' and 'embarrassed' when he lost.
So, I'm not sure, but, to me, that sounds like the horse has some varied emotion.
My horse often shows excitement, fear, jealousy, happiness, and what I think is 'love' for horses. She has a best friend in the field with her, BUT that could only be because horses are herd animals and naturally want to be with other horses, not love or affection.
BUT I hadn't seen my horse in about 11 months cause I sold her and just bought her back. When other people came up to the gait, she'd walk up to them, but that's about it. When I came to see her, she was up at the gait and saw me coming. She started neighing and pawing and got really excited. As soon as she sniffed me, she burried her head in my arms.
So, its hard to say if a horse feels what we consider 'human emotions' but I think they can, to an extent.
