Wow, Charlotte, good for you! I admire your brave and principled stand. You know you have an immune dog, clearly, and further vaccinations for rabies are far more risk than benefit.
In posting this article, it became clear to me that the "out of date" dog who's bitten (not who bites, but who's bitten by a rabid animal), is judged on a case by case basis.
Your dog's high titer is a very favorable finding that would help decide his fate, as is your record of past rabies vaccinations and his current healthy state. If sound minds prevail in this instance, he'd be boostered and observed at home for 45 days. That's what this paper recommended, based on solid data.
I'd print that study out and keep it in his file. You've got the head of the rabies testing lab on your side!
