The musts will be four round of puppy shots, with the first probably starting somewhere at 8-9 weeks and then a new round every 2 weeks or so. She'll get shots for parvo, adenovirus, and a couple of others. If you ever board her or take her on walks or to dog parks, bordatella is an important shot to get too, though I'm not sure at what age. Rabies is critical to get since yorkies were bred as hunters, and will chase down anything (my Cookie Monster has killed lizards, birds, rabbits, and has come really close to getting a squirrel a couple of times). Heartworm medication is a must too. Your vet will give you a better idea than I can on when these should be done,
