My adopted dog is four years old, and she is due for her rabies shot next year. (Philippine laws require a yearly vaccination.) Now, do I have to give her shots for parvovirus, distemper, etc.? She has already had shots for them in May this year before I got her, but since we do not know if her previous owner (if she had any) gave her shots as a puppy, should I still ask my vet to give her the shots?
