I hope everybody is enjoying their new years weekend.
I have some colts I'm hoping to start this year, hoping to start them in a Bosal and later if neccesary transition to a snaffle. Now I know the old vaqueros had a way of starting with the thicker Bosal and then using progressively thinner ones, but my real question is: They put the bosal on under the bridle with the snaffle. How does one do that? The horse isn't wearing two headstalls, but he has both the bosal and his snaffle bit on with two sets of reins. One for the bosal and one set for the bit. How is this done?
