Hmm...have you recently switched foods? Dogs do not take getting their diets changed abruptly very well. You have to bring in the new kind of food gradually with the old kind. if this is not the case, mabe it ate something? If they tell you they don't find anything, wait a week to see if the symptoms go away, and then bring him back. I'm not sure what else to tell you. Try researching.
