If your Havanese puppy vomited only one time, and now does not want to eat, she may have just gotten "sick to her stomach". If she continues to vomit she needs to go to an emergency clinic. If she does not take away her food and do not offer it again until tomorrow morning. Give only a small amount, make sure she is not vomiting, and then you can give her regular meal.
If she starts vomiting again tomorrow she may have a blockage from the jerky and will need to be seen by your regular vet.
