Okay, call me an idiot... I have never owned a dog before, but have recently rescued a Chihuahua (I suspect a mix) that is approximately two years old. I have no clue as to her previous vaccines, if there were any. I also have no clues about her previous home life, except that she has apparently been physically abused. She has been with me long enough to get spayed, a rabies shot, and put on a little needed weight. I have done some reading on vaccines, but every book I have only addresses initial vaccines for rabies. There is a current outbreak of Parvo in my area, and I am a little nervous. Without knowing what she has been vaccinated for in the past, what do I need to have her vaccinated for now, and what kind of boosters do I need her to have in the future to maintain her health?
