Ok, so my 6 year old Tennessee Walking Horse Spirit had a little incident near the arena. I've heard that if a horse like, experiences something really frightening (for example, if a horse is shocked by a water-heater when he goes to get a drink) that it can stay with them and they are scared to go anywhere near it (for example, when you fix the water-heater, the horse doesn't know that it won't hurt him anymore so he doesn't want to drink out of there anymore).
So . . . He's scared to go near the arena and I'm trying to teach him that nothing is going to hurt him there. I've been walking him by it calmly and letting him sniff around and giving him treats when he gets near it, and it seems to be working, but is there anything better? Anything else I can do?
