I had my first dog named Diamond. He was a cute happy maltese dog. He would bark around and keep on running inside our house. But, suddenly, he lost his appetite and began pooping with blood. And the fact that his poop has that "stink" smell. That's when I realized he may have gotten the parvovirus, and to my dismay, I have not yet vaccinated my Diamond.(sob!sob!sob!) What is parvovirus? "Parvo" as is the most commonly used term for parvovirus.
