I would strongly suggest everyone go to the 1st link I have posted as this is the recommendation for vaccines from the AAHA. It is 28 pages but I think it is fabulous.
The 2nd link is from UC Davis with their recommendations. Both excellent sources to help you make an informed choice. Please make sure you throughly read Lepto vaccines as many Yorkies have died from being given this shot.

P.S. I would also space out the different vaccines and not do them all in one day with a Yorkie. I am going with the titer tests and only doing what the law requires. I personally feel we are shortening the lives of our little ones by over vaccinating but I came to this decision by researching many medical sites. My dogs are not like big dogs that run all over the place and I really do not take them out to that many public places.
