Or maybe it should be bone trauma.
Tonight Darby was laying on the couch next to me chewing a bone. I noticed he was acting funny and doing funny stuff with his mouth. Hmmm . . . so I look in his mouth and he has somehow gotten a piece of very chewed sort of soft bone in front of his upper canine in the space where the lower canine fits. So I try to move it a little and I can't. I can wiggle it a bit, but not move it. Darby is still fussing with it so I decide to get some pliers so that maybe I can get a better grip on it. By the time I got back with the pliers, he'd gotten it out on his own. I guess I scared him with the pliers and he decided he'd better get it out on his own!
