We spoke with our vet about this very recently.  We will vaccinate only for rabies from now on.  According to my vet, with toy breeds - once they get their first year booster of distemper, they most likely will have lifetime immunity.  Lepto is no longer recommended by most hoslitic vets as the risks associated with toy breeds and this vaccination far outweight any benefits derived from the vaccine.  We have never had the parvo vaccine or anything else other than boratella and we will only do that if we have no choice but to board (which we don't plan to do).
