About vaccines, I am just a bit chary about giving more than one at a time. Not that I object to the combination vaccines, but, particularly with pups, I break up the rabies and normal combo shots so that they're about a month apart. My adult border collie got very sick once from getting both her rabies and booster shots at the same time. And I know both vets and breeders who recommend spacing things out a bit. I've also heard (though I don't know if there's any validity to it) that over-vaccinating can lead to allergies. But that may be more urban myth than truth.
