My dog is sick and throwing up after his shots. Is it a reaction?

My dog had boardatella and parvo shots yesterday. About an hour afterwards he started hiding and staying away from people. Progressed to drinking excessively, then throwing up. He has started to keep some water down, but not eating and quite lethargic. Any advice?

Your dog may have been having a vaccine reaction. If he is acting normal now then there is nothing you need to do. If however, he is still acting unusual you should have him checked out just in case. It is also important to let your vet know of this possible reaction so steps can be taken in the future to help prevent them. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
