Canine coronavirus (CCV) affects the intestinal tract of dogs. The length of time between swallowing the virus and showing signs of illness is 1 to 5 days. Signs include depression, vomiting, and diarrhea. Some dogs show no signs at all. The illness may continue for 2 to 10 days.
CCV is transmitted through feces, and dogs may shed the virus for 2 weeks after signs of infection have ended. Dogs that have recovered develop some immunity, but the duration of immunity is unknown.
A vaccine is available for prevention of CCV infection. Annual booster vaccinations are no longer recommended because the disease is not too severe. The vaccine is very useful for breeding kennels and animal control situations.
Important Points in Treatment
1. Treatment varies according to the severity of the disease and the age and condition of your pet. Intravenous fluid therapy and hospitalization are often required because dehydration readily occurs in this illness.
