I didn't tie him up with the reins. I had a leadrope clipped to his bridle, but the leadrope was just resting on the fence, since he has tying issues. Fleet has never walked away from being "tied up" like that, since his first owners seemed to have trained him to be tied like that very well.
I would never tie a horse up by the reins, someone at my old barn did that once and the horse got spooked and tried to break away, resulting in mouth injuries.
Fleet's leg just went through the rein when he was lowering his head and when he pulled upwards, the rain just went underneath his armpit and couldn't go any higher. Those reins are fairly new and really strong, so maybe that's why they didn't snap.
You know what, guys? I'm going to be using split reins with this horse from now on!
I also feel so bad about this, I shouldn't have left Fleet by himself, even for just a few seconds. :(
Syd (the horse with the hoof injury) has just had his tetanus shot done about a month ago, should he still get a top up?
