Turnout can be incredibly overwhelming if they aren’t accustomed to it. Imagine it this way:
In your young childhood years you are allowed to hangout with friends, explore the world around you, and only have a few stressful times in your life. Then, life really changes. You are taken from your friends and your home and locked in a small room. Sure, you get to communicate with another species that doesn’t speak your language, and you can see other people, but you can’t touch them or have any sort of relationship with them. You are allowed to be outside for maybe 1 hour but that consists of being around this different species and occasionally being with other people. But it’s now so sporadic that you aren’t really sure how to talk to them. So you don’t. This goes on from 2 years to upwards of 5 or 6. All this happening during your teenage years.
Now you go somewhere else where the vibe is much more laid back. You are turned out in this HUGE space, maybe with fellows, maybe alone. But for years your life had 4 walls and seeing everything all at once is quite overwhelming. You also have new neighbors who assume you know how to talk to them so you don’t. Running is what you were taught to do so you run and run until a different species comes and gets you and puts you back in your 4 walls. No stimuli, and this is what you’re used to.
With all that said, I hope it can shed light on these OTTB’s. We want to do right by them but many people rush this process and completely overwhelm them. Allow the horse to start small. Meet horses outside a fence where they can walk away. Find a buddy they really connect with and let them be with them for a minute. This will help get the horse used to having the freedoms you want him to have, and allow him to explore how to be a horse again.
