Apollo has been bridled in the past but not since I have had him. I went to bridle him for the first time and he wouldn't take the bit. He would stand there calmly while I tried to get him to take it, but he didn't want to, or maybe didn't understand what I was wanting of him? He just stood there with his head low, he wasn't trying to get his head away, he just didn't want to open his mouth. I ended up tricking him with a small piece of carrot and slipped the bit into his mouth. He didn't mind it at all and let me adjust the bridle to his head! He didn't chew on the bit at all and was very good about it, he just stood there contently waiting for me to lead him. I'm just curious how you have trained your horses to take bits and see if any of those work for him!
