Perry(R) SafeTie Reusable Safety Release Tie Tethering a horse can impact a horse's safety in multiple ways. When startled, its first instinct is to escape. If tethered, this natural flight instinct is halted and can result in the horse badly injuring itself. Using SafeTie helps reduce this danger, adding another level of protection to the horse. A step up from rope or string, if your horse panics or pulls back, SafeTie is designed to 'snap' open at a certain stress point to help avoid injury to the horse. This is the SafeTie only. Ring is not included.
