Just got my horse a gag bit aka wonder bit, but someone told me it looks like it was ALMOST
too small. Bits are not very comfortable to begin with so I want to make sure his fits okay and is as comfortable as possible. Plus I do not want it to pinch and cause him to bleed. I have ridden him in it fine and there are no cuts from what I have seen, but can anyone help tell me what a good way to measure for the right size bit is? Thanks!
