I was just cleaning out the coffee maker from this morning and when I dumbed the coffee grounds, some fell on the floor. I was going to clean it when the phone rang and when I went back to it, they were gone. I think Chewy licked them up

My vet's office is closed and when I called another vet, they said they could not give any medical advice. It wasn't a hell of a lot of grounds, but I'm a little nervous. What should I do???
