Completely ill-founded advice. If you choose to, you can wait till one year old, maybe even later, and get a pronounced booster effect from the 16-week shot. Visit ProtectthePets.com with my colleague Dr. John Robb. Super reasonable on titers and he'll explain the results clearly. Here's another article on research showing "out of date" animals actually responded better to a rabies booster than those who were UTD. Oops!
