Bit should be for the Horse’s comfort, NOT the rider’s control
Now, before I go too far, bitless bridles are wonderful and I truly advocate them and ride my horses bitless, but if people feel they have to use bits, here is what I believe:
The bit should be chosen for the horse’s comfort and NOT the rider’s control!
If you can’t stop or turn your horse in a snaffle, it means they need training, NOT a bigger bit!!!!
Snaffle bit I recommend
