what is parvo in dogs

Canine parvovirus, commonly known as parvo, is a highly contagious virus that mainly affects dogs. It is spread from dog to dog by direct or indirect contact with their feces. The virus is resistant to heat, cold, humidity, and drying, and can survive in the environment for long periods of time. Parvo is most dangerous for unvaccinated dogs and puppies younger than four months old, with mortality reaching 91% in untreated cases. The virus affects the gastrointestinal tracts of dogs, causing symptoms such as lethargy, loss of appetite, abdominal pain, bloating, fever or hypothermia, vomiting, and severe, often bloody, diarrhea. If a puppy or dog shows any of these signs, it is important to contact a veterinarian immediately. Diagnosis of parvovirus infection is often based on the dogs history, physical examination, and laboratory tests, with fecal testing used to confirm the diagnosis. Treatment often involves veterinary hospitalization. Vaccines are available to prevent this infection, and good hygiene practices are essential in preventing the spread of the virus.
