Charley gets spooked by Walmart bags, road kill, cats, snakes, buzzards, armadillos, hogs, and dogs that run in packs.
About the only thing that bothers Lacey, is not being able to see Charley. She gets plumb skitish if she doesn't know exactly where he is.
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.
Deer! The husband's horse saw a deer when we were loping and he came to a dead stop. It happened so fast that I saw a flash of deer, looked away to pay attention to my horse, and looked up to see hubby climbing off ground. He did a total flip over horse's head and landed on his back with reins still in his hands. I usually ride behind so I can see all the good stuff they pull.
We used to have a little rat terrier that did trails with us. Hoovey is alright with big dogs, but little ones unsettle him. He doesn't spook, but does keep a really close eye on them.
His major spooking problem is when he trips, if he has no idea what he's tripped on. He'll do it sometimes when I'm leading him, as he likes to walk somewhat behind one of my legs. His leg will sometimes knock mine, and he comes up scared, does a little head toss and hop. If I'm firm with him and tell him what he tripped on, he's alright.
He also hates the porch swing in the front yard, and pieces of cloth on the tack rail (like rugs, shirts, etc.) They're sure to be horse-eaters!
I found something that spooks my horses! My 4yo son fell over a garbage bag that had some empty boxes in it waiting to get put into the burn pile. ( he gets his grace form his momma) The horses were grazing in the yard about 30feet from us. They FREAKED out and took off across the yard!!! Once they got away they both turned around and stared and snorted at Eli like to say, dang it boy! Stay on your feet!
