What an absolute nightmare! OMG, that is just too much to even try to imagine. I am so sorry for the tremendous loss you have suffered. There was a girl who used to be a member here some time back and her Yorkie got Parvo even though she was up to date on her shots. I think it may be like getting the flu shot. This is so very tragic. I would definetly research the Spectra 7 more and find out if it is useless. If your findings are what it seems they will be, you should be compensated for your tremendous loss. Thank you so much for coming on here and warning others.
