Never did I imagine that tying horses and having them stay tied could be a challenge. However with my last two horses I have learned a few tricks to keep those silly ponies tied. Learning to tie a quick release knot is one of the first things you learn being around horses. After acquiring Slick, I had to learn how to step it up and keep him from untying himself. It was quite simple but took some practice. After tying the quick release knot pull the extra slack a little way through the existing loop and continue doing so until you have a braided looking rope. If the end is looped through the last loop the chain will not come undone. However if you need to quickly release the horse, you can leave the tail out of the last loop and if you pull the knot will release.
