Dog Coronavirus: Symptoms and Treatment
📝 Summary
Canine coronavirus is an acute gut infection with diarrhea and vomiting, often striking alongside parvovirus. Puppies are hit hardest and can die in 1-2 days; vaccination and electrolyte support are key.
1 Dog Coronavirus: Symptoms and Treatment
I. Cause and epidemiology
1. Pathogen: canine coronavirus, a coronavirus. Virus is mainly in the gut and passed in stool; spread by contaminated feed and water, via the digestive tract.
2. Source: carrier and infected dogs. The virus is hardy, survives 6-9 days outside and longer in water; once started it spreads fast and is hard to control.
3. Susceptible: dogs; some strains also infect pigs and cats.
4. Epidemiology: low CCV rate (~30%), global, peaks in winter, spreads fast, often hits a whole litter in days.
II. Symptoms
1. Puppies are worse, mainly gastroenteritis.
2. Early: vomiting lasts days until diarrhea starts, then eases or stops. Stool is pasty, semi-pasty, or watery orange/green with mucus and blood.
3. Low mood, lies down, no fever. Rapid dehydration and weight loss; untreated puppies often die in 1-2 days. Adults are mild.
III. Diagnosis
Hard to tell from parvo or rotavirus, and mixed infection is common. Proper diagnosis needs electron microscopy of stool, virus isolation, or fluorescent antibody testing by a vet.
IV. Prognosis
Death rate is higher in puppies; lower in adults.
V. Prevention
Vaccinate regularly. Supportive care keeps electrolyte and acid-base balance and uses broad-spectrum antibiotics against secondary infection.
