Titers are not a byproduct of nosode use, just FYI. While they protect well (used properly, as I mentioned), they are not physical, so they don't protect by titer creation (antibodies). I suspect you either did Natural Exposure or perhaps this pup, while on nosodes, just got out and got exposed to the virus. In the end, that's how titers are best achieved anyway: a resistant pup developing antibodies from living in the real world.
And kudos to your homeopathic vet for being able to treat that itchiness so effectively with a remedy!
