Julia should be examined by your veterinarian today. Vomiting and a lack of appetite in a puppy can quickly lead to dehydration which can kill. If she is not vaccinated, diseases such as distemper should be ruled out. At the very least, she may need supportive care (IV or subcutaneous fluids, anti emetics and parenteral nutrtion) until she is eating on her own and not vomting any longer.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Mavis! Yes, I think you should have her seen today by a Vet. She is just a little baby and we worry about dehydration and low blood sugar. Plus puppy's thing young can deteriorate quickly. Bring a stool sample if you can and all paper work you were given regarding medications, vaccines and deworming. Possible causes are: intestinal parasites, viral or bacterial infections (parvo is a concern), dietary indiscretion, food allergy/intolerance, toxin ingestion, reaction to a medication. I hope this helps and I wish Marvis the very best!
