So, lately (like the past week or two), Sadie has picked up a lovely habit of keeping chewed up food in her mouth. She doesn't play with it, she just chews it up and lets it sit in there. Forever. Yes, it's as disgusting as it sounds. She does it mostly with crackers. She will just let the food sit in there until I can somehow bribe her to swallow or I physically pull it out, which makes me gag/throw up. It happens 1-2 times per day.

Anyone else have experience with this? Any one know why she would be doing it? How do I stop it?!
