Apparently, now if your dog gets parvo there is a medication for it. www.parvoguard.com I don't think it should be an alternative to getting your dog vaccinated against parvo, though.
I have a big problem with this. Parvo is a very serious and deadly disease. I can't believe they expect owners to diagnose parvo themselves. That is rediculous. A lot of dogs get diarrhea and vomit for many other reasons other than parvo. So this company is banking on ignorant people thinking, "Oh, Buddy vomited today and had diarrhea. He's kinda lethargic too. Must be that damn parvo. Better go get some parvoguard and treat it myself so I can save all that money." When actually the dog ate something that made him sick or is sick from some other disease that will, in turn, go untreated. What a fabulous money-making scam.... ~Peace~
