Some symptoms of parvovirus in dogs are fever, loss of appetite and vomiting, according to the American Veterinary Medical Association. Another symptom is frequent bouts of bloody diarrhea. Parvovirus is considered a medical emergency.
Parvovirus is an extremely contagious disease, says the American Veterinary Medical Association. Dogs catch it from being exposed to infected dogs or even infected people. They can even catch it from their food or water bowls and the surfaces of kennels. It can be transmitted through collars, leashes, shoes and clothing. The virus is exceptionally hardy and can resist drying out and high humidity as well as heat and cold. It can live for a long time in the environment.
Once the dog has contracted parvovirus, the treatment is to isolate the animal and keep it hydrated, as diarrhea and vomiting will rob the dog's body of fluids, says the American Veterinary Medical Association. The dog is also given treatment to ward off other infections while its immune system is compromised. As of 2015, there is no drug that specifically targets parvovirus.
The best treatment for parvovirus is preventing the dog from getting it in the first place, says American Veterinary Medical Association. This means that puppies should be vaccinated and adult dogs given booster shots. The dog's owner should schedule parvovirus shots with the dog's veterinarian.
