Ellie May is correct - any dog can get it, but it's worth adding that more and more fully-vaccinated dogs, both puppies and adults, are being infected this year because of the evolution of the latest strain of Parvo.

The newest strain is called 2c (but it's also popularly known as the F-Strain). It's much more aggressive, with symptoms appearing at a highly accelerated rate. For example, whereas bloody diarrhea typically appeared in two to three days with older strains, it can appear within the first few hours with the 2c strain. In fact, some dogs are dying within six hours of symptoms first appearing!

As for titering, this does have its pros and cons. I fully accept that annual booster shots are becoming more and more unpopular because of the health risks involved, but the downside is that the titer only tells you about the titer that day, not the protection. According to the resident Parvo expert at one of the leading vaccine manufacturers we spoke to, nobody is really sure how to interpret titer results: some dogs with low titers have been shown to be protected, and vice versa.
