Parvo can result also in intestinal and heart damage.
Lethargy Vomiting may be severe and repeated. Diarrhea may vary from loose and runny stools to tight, projectile- like stools with bloody discharge. Most cases of parvo are found where dogs assemble, such as parks, dog shows, kennels, pet shops and humane shelters. People may contribute to the spread of this virus by carrying infected fecal material from place to place on their shoes. Dogs exposed to canine parvovirus may pick up the virus, although a small percentage may actually show signs of disease.
