Canine coronavirus is a
Coronaviridae that causes a highly contagious intestinal disease
in dogs. The virus invades and replicates in the
small intestine. Symptoms include
diarrhea, vomiting, and anorexia, but most cases are very mild or
without symptoms. The disease is spread through the
infected dogs, who shed the virus for more than two weeks following
incubation period is only one to three days. Diagnosis is through
detection of virus particles in the feces. Treatment usually only
requires medication for diarrhea, but more severely affected dogs may
intravenous fluids for
dehydration. Fatalities are rare. The virus is destroyed by most
disinfectants. There is a vaccine available, and it is usually given
to puppies, who are more susceptible to canine coronavirus, and dogs
that have a high risk of exposure, such as show dogs.
A more serious complication of canine coronavirus occurs when the dog is also
canine parvovirus. Coronavirus infection of the intestinal villi makes the
cells more susceptible to parvovirus infection. This causes a much more
severe disease than either virus separately can.
