Most puppies will go to their new home with their first vaccination shot given between 7-8 weeks.  There are some smaller breeds which do not place puppies until they are a little older, and in these cases may already have their 2nd vaccination shot.
We always recommend you follow your breeders timeline schedule, recommending when you should vaccinate your puppy.  Your veterinarian will also be helpful with this schedule.
It is very important to remember to give the vaccination records you receive from your breeder to your veterinarian, over vaccination is not good for puppies.
Vaccination Logs will have been sent with your puppies information from your breeder.  If you click on your puppies profile page on your dashboard you should see all the necessary information to pass on to your veterinarian.
This article provides a basic timeline for vaccination schedules.
