Supposedly, a dog that we used to have (got too big, it was my parents dog, and they couldn't deal with it, was knocking them down which isn't good), died of Parvo even though it was fully vacinated and everything.

Had a cat that we had forever died recently with its system shutting down, and while dad didn't have any of the cans, he had fed it lots of the different types that have now been itentified as contaminated.

Hopefully yours is just something minor
