Hi there. We don't normally recommend vaccinating pregnant dogs, since if she would happen to have a reaction to the vaccines, this could cause significant problems for the developing puppies or even cause her to lose the pregnancy. So if you think Rosie might be pregnant, I would recommend waiting until after she's had the puppies, and then having her vaccinations updated.
