Hi Florence,
It's not a given that the immunity will be present in the next generation, no. In fact, I'd highly doubt it. And there's no way of telling in Suzi's case, but she may well have received some rabies immunity from exposure to the newly vaccinated dogs who were in the same vicinity at her shows.
You can titer to find out for sure, which I'd recommend, but be sure if you opt out entirely, you read the Vaccination: Rabies page and understand fully the risks inherent in zero vaccines.
