If you expose your Papillon to other dogs that have recently been vaccinated for rabies, his titer should go up. I have had puppies who have never had a rabies vaccination show rabies antibodies when titers were run....they were exposed to the virus through shed vaccine in other dog's urine and developed immunity (a much more natural process than an injection straight into the muscle tissue). If you aren't required to vaccinate against rabies, I wouldn't!
