Washington state does allow for a 3 year vaccine, see below:
That's an interesting piece of information.
We just moved back to Washington State this year after being gone for 25 years. We have an SOB (Some Other Breed, i.e., not a Basenji) dog that we took to a vet here and she gave her only a 1-year vaccine, so I just assumed… .
It's sort of a moot point for us, though, because we will normally be in Arizona at the time the rabies vaccine comes due again, so we'll just have her vaccinated there, as well as any Basenji we get.
By the way, I couldn't get the first link to come up...keep getting a "can't find" message.
