Im not much of a dog biologist (like...at all) but i personally think the less vaccines a dog gets, the better. There has been a steady increase in things like cancer in dogs, along with the steady increase of vaccines they get. Although, saying that, some are definately necessary in this day and age. I guess its all about finding that line between too much and too little.
Since i personally dont have much experience on this matter, i wont bother to give my opinion on which is better. I think veterinary opinions are the most important here. They did, after all, go to veterinary school to learn abotu these sorts of things.
