So this has been going on for a while. My horse get scared and wants to spook when a horse comes running up behind him or beside him or infront of him... is there any way that I can help that and make it so he doesn't freak out????
This one often requires a lot of work and you'll need some help. This is a very natural reaction...after all, if the other horses in a herd start to run, there must be something to run away from. To start, get some other riders to slowly approach you while you keep your horse steady and calm, and then gradually increase the speed.
Be aware, though, that running up on another horse is generally considered to be very inconsiderate for exactly this reason (at least on the trail).
