The AAHA has updated their website again, so the link to their guidelines in past threads probably won't work anymore. Here's the current link:

In a nutshell, AAHA recommends these core vaccines for every dog:
Parvo, distemper, and adenovirus2: 3-shot puppy series, 3-4 weeks apart, between 6 and 16 weeks (as a side note, most vet schools recommend 8-9 weeks as the minimum age for most breeds); booster one year later; booster every three years after that.
Rabies: one dose anytime after 12 weeks of age (many people feel later is better for this one, or at least 3-4 weeks apart from the other shots, but there are legal mandates in many areas for rabies vaccines); booster one year later; booster every three years after that (unless law requires it more often).
Non-core vaccines, given on an individual basis to at-risk dogs:
Bordatella (kennel cough)
Borrelia (Lyme)
Lepto
Not-recommended vaccines:
Coronavirus (some immunologists have called this "a vaccine in search of a disease")
Giardia (vaccination has not been shown to prevent infection)
Some alternative protocols, from Ronald D. Schultz, PhD, ACVIM(H), Chair of UW-Madison's Veterinary Pathology Department:
Minimal
Parvo/distemper/adenovirus/rabies at 12 weeks or older; rabies booster one year later; rabies booster every three years (other vaccines would not be boostered).
Moderate
Parvo/distemper at 6-9 weeks; parvo/distemper/adenovirus/rabies at 12-15 weeks; booster all one year later; booster rabies every 3 years, others every 3-5 years.
(This is similar to what Jean Dodds, DVM recommends, though she suggests titering after the first-year booster rather than blindly vaccinating)
Maximal
Parvo/distemper at 6-8 weeks; parvo/distemper/adenovirus at 9-11 weeks; parvo/distemper/adenovirus/rabies at 12-14 weeks; booster all one year later; booster all every three years.
One important thing that the AAHA notes, and the AVMA supports in their position statments, is that the vaccination protocol should be tailored to the individual dog (excluding legal mandates, of course). Not only because of regional differences (as far as risk/exposure to some diseases), but because of genetics, lifestyle, and environmental factors. (Rottweilers, for example, and other black-and-tan breeds have different requirements for parvo vaccination, needing high-titer vaccines at younger ages. Many natural-rearing, raw-feeding breeders don't vaccinate at all, but this is generally not a wise decision for conventional-rearing, kibble-feeding owners.) (Another important thing about which both organizations agree, though not specifically about puppy shots, is that annual vaccinations are unnecessary; the AVMA does not suggest a specific revaccination interval, the AAHA has picked three years as a random compromise number.)
