Late last July she was tricked into a stall ....
being tied in the trailer was the FIRST time she had ever been tied. ....
Due to my schedule, she got basically ignored for the next six months. I would take her out, tie her to half a cross tie near my gelding while I was saddleing up
Respectfully, that & the rest of what you've said doesn't sound like she has been taught how to tie much at all. She's just been forced into that situation & happened to have handled it in less confronting situations. From what you tell in your second post, it sounds like she *may* be up to being tied when in company, but not when left alone.
This was a bad mistake and she has learned that the stretchy cross tie that is several feet long gives her lots of room to be a brat - including bucking and rearing if I walk away.
Perhaps careful consideration of WHY she is doing this & changing her motivation, rather than just focussing on stopping it might lead to a better solution. I suspect it is not 'play', but especially as you call her 'buddy shy' that she is not confident being left alone & trapped in this situation & so *teach* her how to tie, and with ***gradual*** desensitisation, that it is OK for her to be alone.
So I got her nicely short tied and walked off while the royal freakout happened behind me.
I would not have tied her at all in this situation & certainly not left her alone. Horses can really hurt themselves in that sort of situation & I personally want my horses to be confident about this sort of thing, rather than a shut down, hopeless attitude towards it & the things humans do to them.
I left her there for about two hours
I do agree that extended periods of time being tied up is a good training step, given what most of us will ask/expect of our horses. BUT I would ensure she was good with the basics first & *teach* her to accept it, rather than just forcing her to.
When I deemed she was well trained enough to be tied(rope looped around, not tied firm) & left, especially if she was nervous about being alone, I'd start out going out of sight(&/or taking her buddy away) for SECONDS, not minutes, let alone hours. The aim is to prove to her that it's no big deal, not make it a huge one that she's forced to put up with.
2) Unless it is in the three seconds after a BAD bahavior when I want them to KNOW that I am going to skin them ALIVE (and that only gets to last for 3 seconds) I do not allow a horse I am working with to be afraid. Fear doesn't teach anything I want them to learn.
Um, if you acknowledge fear is not productive to learning, I don't get how you justify causing them to think you're going to skin them??? Not that I'm dead against punishment, but it's not the most effective teacher, especially if the horse becomes afraid.
That '3 second rule' that people talk about is specific to behavioural research on dogs and is a bit misunderstood otherwise. Studies have shown that animals have extremely limited abilities for understanding abstract concepts, such as a consequence for a behaviour that happened in the past - that is, any time in the past. For an animal to clearly understand the consequence, it is best if it happens *AT THE TIME OF* the behaviour we want to effect. Studies have shown that, with *consistent* consequences, dogs can generally associate *within* 3 seconds of a behaviour. Horses have been shown to have no understanding of a consequence if it's more than a second or 2 after the behaviour.
