Thanks, gdolapp, the firecrackers are a good idea! I have done a lot of arena desensitizing already. She's not afraid of plastic bags, tarps, empty water bottles, blankets, etc. The boarding stable I used to board at had a radio playing in the barn 24/7, so she's fine with that. She walks through water, over bridges and stuff too. We compete obstacle trail in an arena and she's great with it. Like I said before, she has never refused to go anywhere I directed her. She'll walk into/through anything I ask her to, and she's not afraid of anything I present her with. If I walk her into an arena with a bunch of stuff in it, she may look at it, but she won't spook. She's good with kids, barking dogs, cats etc. I even rode her in a pasture with a bunch of turkeys. I've ridden her on the road and she doesn't mind traffic. She doesn't care about it if she can see it. It's only the unexpected stuff, like sudden, loud noises, animals jumping out of the brush at her, and that one time she was stung by a bee. I expect her to be startled by this stuff (heck, I'm startled by it). I just want her to learn not to teleport out from under me when it happens, so I'm looking for tips on how to stimulate these unexpected situations, and how to handle an explosive spooker so she doesn't just get away from you when you're stimulating these situations.
