OK, so on to the bosal, bitless bridle, sudepull issue.
Because you have one of those crossunder, leverage-with-rings, ‘indian’ bitless bridles, right?
Those are really Frowned Upon by folks such as Dr. Deb Bennett and Buck and such. They give a pull in the wrong side of the horse’s head, and with the leverage applied from the crossed-up rings, they don’t release at the right time (which is the really Frowned Upon part of the design.)
So the folks who Frown Upon a crossunder-type bitless bridle, often very much recommend a sidepull, whose signal is more clear to the horse and does not confuse the release with a leveraged tightening around the muzzle.
So, my suggestion for now if you are riding sans bit because of teeth problems, that you go get a regular sidepull.
BUT, but but but but
you have posted before this as well that Mac goes really nicely in your Frowned Upon Bitless Bridle.
If Mac is following your lateral requests, he understands your opening rein (and indirect rein) cues and the thing Never tightens around his muzzle…
than there is no reason to get excited about all the Frowning, because the HORSE is telling you that he understands clearly what you are asking.
So, of course you have heard, in a similar vein, that when your horse is wearing his snaffle outfit with mecate rein, that you ONLY do groundwork with the horse going counterclockwise, because if he is going clockwise and you pull on the mecate you will pull on the bit on the wrong side of his mouth and confuse him.
Yeah, no, you haven’t heard that.
If the horse gets confused in groundwork on the snaffle mecate rein with the bit pulling in the ‘wrong’ place, because you HAVE to put a physical pull on it, you go back to the halter. You go back to the halter to make things more clear to the horse.
Once the horse can follow your feel in the groundwork, once he learns on the halter, you put the snaffle outfit back on and you can send him either direction on the mecate rein without confusing him. You can get off and send him through a gate using your mecate rein, turning him whichever direction he needs to go for that particular gate, you won’t pull the bit on the wrong side of his mouth and confuse him, because he can follow your feel.
Yes, the bosal is MUCH more a longitudinal tool than a lateral one.
But if the horse understands clearly what the lateral hand is asking, it works just fine in a bosal. The key is that you do not PULL on a bosal. The bosal is a tool of signal. The bit (and sidepull) are tools that are expected to have lateral PULL on them, until the horse learns to follow the feel.
So if you PULL laterally on a bosal, you will make a mess.
If you use the bosal with a lateral SIGNAL, it works just fine.
There is a beautiful photo of Martin Black, in his Cow Horse Confidence book, of Martin using a direct rein while circling a cow, showing a horse called White Eye in Elko in 1983. There’s a big loop in the rein- Martin is not in any way PULLING sideways.

In his Working Cattle in the A Pen, Martin also uses that lateral rein on his hackamore horse to set up his horse to turn the cow. He’s basically just getting his horse into a leg yield, so the horse can turn the cow and move off balanced, in the correct lead.
He also does that with his snaffle bit horses, but his bridle horses don’t need it, they know how to make that turn without Martin setting them up to help them.
