Always assume puppy ate something. They inspect/speak with their mouths.

Watch her for her for a few hours. Check for any change in behaviour, bleeding from mouth and pooter. When she goes potty, check her stools (best way: If you have clear plastic sandwich bags, place poop in one, seal and then smush to view the contents). I know.....EWWW GROSS!

Call your vet to give them a heads up and see if you can give her a little pepto to coat her stomach just in case she did.

Until then, there really isn't much you can do. If you take her to the vet, the vet will just perform an X-ray, look at a stool sample, check her mouth, and charge you. Same exact thing you are doing now.

Keep us posted please.
