Replies on Your Dog Bit Someone and Out of Date on Rabies Vaccine?

Hi Tracy,
With rare exception (very, very rare), I recommend every dog get a rabies vaccination sometime after 4 months of age. The odds of lifetime immunity are high if you wait till that age. Then, yes, you have proof of vaccinated vs unvaccinated, a much better position to be in.
International travel: every country you go to will have immutable rules that you must follow to get in. No wiggle room there.
