Lol, I decided to put a bridle on my mare today for the first time too. She's weird though. She actually did very little chewing, she spent most of her time with pursed lips refusing to open her mouth for fear of the weird thing sitting in it lol. She did the same thing the first time I buted her with paste bute. She didn't swallow or try to spit it out. Just stood with pursed lips. Unfortunately my cob size bridle is a bit big even on the last holes. I just wanted to see if it would fit, and as she still has her wolf teeth, I didn't do anything other than have her stand there with it on. He's a cute guy, and he's going to be big. At least he seems to be quite good natured.
