I'm not sure why the vet has suggested putting off an exam, but I'd find a vet to take this very serious (today) because it is not normal. Could be a partial obstruction, pancreatitis, puppy diseases come to mind. With a small pup, dehydration can set in quickly which can be life threatening. This pup needs xrays and blood work and possibly fluids immediately.
