Yep Def Dragons!! Mia has found Dragons in socks, My underwear, some of the walls in our house, Her tug rope toys, and a couple of beds. She is better now but Duke has been finding them lately. Found one in is Wubba last night.
Sigh.... I knew it would only be a matter of time.
My Mia is the queen of eating stuffies. Just watch her to make sure she is not bloated, eating normal and drinking normal. If something is lodged usually they will throw up ANYTHING even water cause it can not get down. She should be fine if you have not noticed anything in a day. Probably dont need to make a vet appointment but since I see you already have one I would ask just to put your mind at ease.
You may see some stuffing come out in her poop though.
