Ever since I've had my horse (about four years) I've noticed that he holds his head in a weird way when he eats. He pokes his nose out and sometimes will tilt his head. It's almost looks like he's saying "nanner nanner look what I have" because he'll shove it at you if you're standing near him. He doesn't really drop food, just a little piece here or there like most horses. Oh, another way to describe it: it kinda looks like he took a giant bite of food and is trying to chew it all at once. He gets uber excited for feeding time and will practically bust his bucket off the wall or run you over to get to his feed. His teeth are done annualy, and like I said he has been doing this forever as far as I know. I've never noticed anything odd about him like showing pain, and he definitely hasn't lost any weight. He's at a very healthy weight, very fit, and has a nice shiny coat to show for his yummy healthy feed.
Also, just a question I've been wondering for eternity, can a horse hurt his teeth, jaw, etc. by biting into a super thick carrot? My guy gobbles his up and doesn't drop even a teeny tiny piece, but I've always wondered.
So anyway, is the head thing just a goofy habit/quirk?
Oh yeah, and I've seen some other horses do this as well. ;)
