The Sierra Horse Halter is a training tool for getting your horse started right! Stop habits before they start by using the SHH right in the beginning. But!!!!!...If you have a problem to deal with now, fix it. The SHH will deal with problems like your horse leading you instead of you leading your horse. Pulling back when tied, or difficult trailer loading for no other reason than he does not want to. See extreme cases on my web site. The video here is one done by a valued customer who knows how to use this wonderful tool while also using Natural Horsemanship methods. More of this kind to come. The SHH is sold on my website at PFLus.com or mysierrahorsehalter.com Call and I can take your cc over the phone. Call with questions or concerns. Thank you.
