Canine coronavirus is a highly contagious intestinal disease that can be found in dogs all around the world. This particular coronavirus is specific to dogs, both wild and domestic, replicating itself inside the small intestine. Canine coronavirus is, however, limited to the upper two-thirds of the small intestine and local lymph nodes of the dog. Despite its prevalence, it is generally considered to be a mild disease with only sporadic symptoms.

 The incubation period for canine coronavirus is one to three days after contact. The disease is highly contagious and is spread through the feces and saliva of infected dogs. The virus is usually shed for six to nine days, but cases lasting up to six months following infection are not uncommon.
