Yep, the risk for those of us in the other 32 states is that if there's a scratch, a tooth caught accidentally on a house guest while turning the head, or some other freak accident from a gentle old dog, the dog can be put down. Titers do not count under the rabies laws in many states.
In my state, in a bite case (which might just be a scratch with a toe nail) with an unvaccinated dog, AC has the right to insist on euthanasia, decapitation, and sending the brain to the state vet school for analysis. A 10-day rabies quarantine (in the public shelter, under terrible conditions) is sometimes possible at their discretion; normally the 10-day hold is only for vaccinated dogs in my area. Even in that situation, an old dog would be in loud, scary, horrible conditions, on concrete without a bed, eating cheap food, with no walks or time out of the kennel for 10-days (because it's on rabies observation).
