You asked a question yesterday about how many rounds of vaccines puppies need. It is somewhat dependent on your area, but generally speaking they need boosters every 2 to 3 weeks until they get they are around 4 months old. The rabies is usually the last shot they get, again that is determined by the laws in your area. Each state (and sometimes counties) regulates that in accordance with the incidence of rabies in the area. Check with the vet you will be using and they can tell you what they recommend.
