I'm not sure if this is the answer you wanted but... If my horse won't slow down I ride her in small circles until she slows down. This really works well and is a good emergency stop.
Thanks so much. I don't use a bit but I'm sure it's the same as riding in halter😅
I tend to use my seat to slow down as my horse also fights against my hands, if I sit deeper in the saddle and squeeze slightly with my upper legs whilst applying a bit of pressure on the bit he always slows down :)
I would take you up on that but I don't use a bit. If I did I would definitely change it out though. Thanks anyway💚
That did help. I do turn him in circles when he tries to trot/canter before my cues. But the other tips are some that I am definitely going to try. Thanks💚
My mare does exactly the same sometimes, especially when she's excited. However, she tends to rush most of the time due to being unbalanced (she's very green in the school).
If you're riding him and he isn't slowing, no matter how hard you're pulling back, you can make him work more by asking him to move faster, so he realises that going faster will result in him losing some weight and working even harder than he'd planned to! (making the wrong thing hard and the right thing easy!)
...or you could ride him in tight circles, which helps me a lot when I feel I don't have the control necessary when my mare begins to rush.
Doing some steady direct transitions and doing random, unexpected turns and stops makes them pay attention to what you're asking of them. A lot of horses tend to speed up because they're focusing on something other than the rider's requests. For example, a horse in the other field may giddy him up so he'll be wanting to go over there and, as a result, begin to speed up without being asked.
Good luck! ~
Change the type of bit your using and see if that helps if not do a lot of canter to trot and trot to walk transitions
