My horse is scared of candy wrappers.. probably because they are small, shiny, sound strange, and seem to show up everywhere. He also chooses on certain days to spook at a barrel. Today he did not spook.. but yesterday and the day before he jumped sideways honking and huffing.
He is also scared of men. But that's not strange as men did hurt him in his past life.
He also is scared of flash lights. If you shine a light on him, he will run away and get very worked up. We're still working through it :P
I love my horse, haha
