I have a six year old showjumper who is very talented and confident about his job but has always had a big problem with grinding his teeth. Although he still performed well and many people said that it was nothing to worry about, just an annoying habit, I have been trying many different bits, bridles and different schooling to help him relax as I believe that he cannot be comfortable or relaxed when he is constantly grinding his teeth. None of the changes that I made helped him and I found it quite upsetting that I couldn't help a horse with such a lovely, genuine personality to control his stress levels.
I came across Gumbits at the Dublin Horse Show last year 2014 and was doubtful that they would work as I had tried so many approaches with him but I have been amazed at the results. He is a horse that has never really liked a bit in his mouth, even though all that I use are soft plastic bits, and the stressing used to start as soon as I started to get him tacked up both at home and away, he would start violently shaking his head and get very unsettled and, as you can imagine, this made settling him in the ring very difficult. I now give him some Gumbits before I get any of his tack and he has relaxed so much that all of the stressing, head shaking and tooth grinding has stopped, he is also now incredibly light and soft in his mouth.
Since I have started using them, I would not be without them.
