I have owned two Havanese at different times who both went through teething. Nothing like you describe ever occurred. Did the vet tell you what was going on? Our first Havanese was "gagging" and it turned out to be kennel cough she contracted when we left her with a breeder for a few days. Even though you can vaccinate for it, there are so many different germs that can cause it, it is not a guarantee they will be protected.
If the vomiting persists, I would seek another opinion at an emergency clinic which may be the only place open through the holidays. Good luck, and wishing you the best.
