Canine corona-virus is an acute and highly contagious intestinal disease of dogs.  The disease causes depression, vomiting, and diarrhea.  The symptoms are similar to canine parvo virus; however the disease is less severe and fatalities are rare.  Occasionally, very young or weak puppies, as well as older geriatric dogs, become severely dehydrated and die from the disease.

Most dogs infected with canine corona-virus have no symptoms.  These animals are often the source of the virus for healthy, non-infected dogs.  Particularly susceptible to the disease are show and field trial animals and dogs that are kenneled (boarded).

Canine corona-virus is transmitted from the feces of infected dogs to non-infected animals via the oral route.  Infected animals can shed the virus for several months after clinical symptoms have disappeared.  Asymptomatic dogs shed the virus as well.

Since canine corona-virus can cause severe vomiting, diarrhea, and dehydration, veterinary care is required.  Using laboratory tests, a veterinarian can distinguish between canine corona-virus and parvo virus.

The effectiveness of canine corona-virus vaccine is controversial.  Your veterinarian can recommend a prevention strategy that is specific for your pet.
