Two apparently novel viral gastroenteritides of dogs were recognized in 1978: one caused by a parvo-like virus (CPV) and one by a corona-like virus (CCV). A rotavirus has also been tentatively associated with neonatal pup enteritis. Canine viral enteritis is characterized by a sudden onset of vomiting and diarrhea, rapid spread and high morbidity. Treatment is only supportive but must be initiated promptly. Infected animals should be isolated immediately; the extremely contagious nature of these diseases makes them difficult to contain. Feces from infected dogs appear to be the primary means of transmission. Sodium hypochlorite solutions (eg, Clorox) are recommended for disinfection. The development of effective vaccines is an immediate and pressing problem.
