Not excusing the neighbors, but I’m wondering what exactly happened.
When you say you were thrown - do you mean you fell off when the horse spooked, or did it buck you off or rear or something?
The latter two reactions seem a little extreme over dogs and loud people, but maybe you’re riding green horses? If so, I’d do some work on the ground first and then under saddle to get them used to dogs running at them. Warwick Schiller has some good free you tube videos about dog proofing horses (and car proofing, etc.)
If it’s the former, I sympathize - my old barn had a blue tick hound with a wicked sense of humor who liked to leap out of the bushes and scare my first horse. But you know, I got really good at sitting a spook.:yes: And after awhile I began to suspect my horse thought it was as much of a game as the dog.:rolleyes: Anyway, maybe you could look at the situation as an opportunity to develop some new riding skills? I’d recommend Sally Swift’s classic, Centered Riding, especially the first four chapters.
It’s a shame, but you probably can’t do anything to change the neighbor’s behavior. But just imagine how good it will feel when their shenanigans don’t bother you or the horses anymore!
