Mine isnt afraid of much either. She does like Dumas said, stops and stares, rarely any major sideways spooks. We were in a parade last year and got behind some antique cars that were backfiring. That made her a little nervous but I was nervous too so it could have been me
Only one time in all the miles we have gone has she refused to go through something. We were crossing a creek and she was standing on a rock ledge in the water but to cross she had to step down into deeper water we couldn't see the bottom of. She wouldn't step down and I gave up trying to make her. I guess I trusted her judgement on it. She normally has no problems with water. Who knows maybe there was a snake down there
Just had to find a better place to cross.
