Is my horse's bridle fitted properly?Photo. 10p.?

You already know that the flash should go under the full cheek piece. Your noseband is a little low. When you have a flash noseband, the caveson should be about one finger width below the cheek bone. Also, the browband is just a hair high. And the throat latch is probably too tight. You should be able to fit a fist under the throat.
