Canine Parvovirus has been cited as the most common cause of infectious enteritis in dogs worldwide. Other causes of viral enteritis in dogs include canine distemper virus, canine enteric coronavirus, rotaviruses, astroviruses, adenoviruses, caliciviruses and novel viruses that include a norovirus, kobuvirus, sapovirus, and possibly also a circovirus. Canine enteric coronavirus usually causes mild diarrhea in puppies less than 6 weeks of age. It can also be seen in conjunction with other viruses such as Canine Parvovirus. Rarely, canine enteric coronavirus has been found as a cause of more significant diarrhea in young dogs.
