What are the signs of canine coronavirus?
Most coronavirus infections are subclinical, meaning not severe enough to present observable symptoms, and produce few clinical signs in dogs.
However, infections can occasionally trigger more severe symptoms, especially in puppies.
The most typical symptom of canine coronavirus is diarrhoea, usually sudden in onset.
This is usually followed by a period of torpor and decrease in appetite.
Stools are loose, with a particularly unpleasant odour and may contain blood or mucus.
If a young puppy has a mixed infection, for instance both coronavirus and parvovirus, expect the illness to be more severe.
