this reminds me of when My dog Felice got a marrow bone stuck on her bottom jaw. some how she got it behind her bottom fangs. We couldn't get it off. when she started to freak out she bit down and cracked it ( mind you it is a part of a cow leg!)all the way through on one side but we couldn't bend it we were scared we were going to break her teeth. story made short we went to the vets and as we were going in the door another dog was comeing out. my dog felt volnerable and grabed the bone with both her feet and pulled it off. Thank god.
