Should we see the vet?

My dog threw up this morning and it consisted of about a third of a cup of chewed up toy that disappeared last week, a few small rocks, a small piece of a plastic basket that he chewed up and dog hair. He is not acting sick, has normal stools and eats well. He did have a few pieces of the missing toy in his stools last week, but just a fraction of what I found in his vomit.

He is 11 months old, about 95 pounds. He is a mixed breed rescue, but looks very much like an Anatolian Shepherd. Do you think he needs to be seen or can I just wait this out. I will post again if he has any changes, but he has only thrown up this once.
