Rabies is mandatory every 3 years here.. Like @JAKEISGREAT there is a lot of wild dogs and other animals in this area, it's very scary if my dogs came in contact. I am not pro-vaccine per say, I even have my human girls in a modified vaccination schedule, minimally and stretched out. But, I cannot risk them my dogs getting rabies. I will stretch it to the max 3 years and will not give the other yearly ones that they recommend, just the puppy series plus one more in one year to guarantee the vaccines took... My vet recommended rabies at 12 weeks, and I told her I would wait till 16 weeks, so I think they will have somewhat of a more developed immune system. They are getting it this saturday, Katara will be 17 weeks and Aldo 16..
