It was a stem about ain inch and a half long but kinda thick and with a couple of branches. I guess one of the dogs ate it because I can't find it. And they're both acting crazy as usual, but no one's getting sick. The primary stem thief is actually sitting behind me at the moment, now shredding and eating a paper towel. Knucklehead dogs. I think all is well. Now I know what to do with stems!
