Our goal with this study is to create awareness about what you cannot see in your horses mouth while they are performing with the bit or bits of your choice. The bits we used in this study can be found in most every ropers tack room. Additionally the horses used are 3 and 5 years old. The 3 yr. old was pictured with bits more commonly used on a younger developing horse. The 5 yr. old was pictured with bits more commonly used with a more developed broke horse. Points of interest are, tongue pressure and soft palate pressure. Feel free to draw your own conclusions from our visual clinical study. Let’s Rope.com is committed to continuously creating awareness on important topics relating to equine sports.
We would like to Thank Dr. Kurt Heite of Brazos Valley Equine Hospital for their facilities and managing our study.
Seventeen years ago, my husband and I were sitting in the living room with our family discussing a possible South Texas Tack. Little did we know that it would become reality. Ever since that day Steve and I have worked together to help bring you the best that the western lifestyle can offer in products, service and knowledge. The knowledge we share is from our experience and observations. “A Bit of Knowledge” is one of many articles that was written to share with you.
Come See Us. I would love to hear from you.
For the love of Horses,
Nancy
