How long does it take parvo to kill a dog
This is especially dangerous in very young puppies. Most deaths from parvo occur within 48 to 72 hours after the onset of symptoms, which is why itâs critical that you take your dog to a veterinarian or emergency animal hospital immediately if he shows any signs of the infection.There is no specific anti-viral therapy for parvovirus 2c (or any of the other strains). Symptoms of parvo include vomiting, severe and often bloody diarrhea, lethargy, fever, and loss of appetite. 2  Dehydration from the vomiting and diarrhea is also a serious concern.
