Canine respiratory coronavirus

How is CRCoV transmitted?

CRCoV is transmitted through direct contact with infected dogs or their secretions. The virus can be detected in nasal, eye and oral mucous membranes as well as in the feces of infected dogs. The risk of infection is particularly high in confined spaces such as animal shelters, boarding kennels or dog shows where many dogs come together.

What symptoms does a dog with CRCoV show?

The symptoms of a CRCoV infection are usually mild and similar to those of a cold. These include

• sneezing
• coughing
• nasal discharge
• fever
• Loss of appetite
• lethargy

The symptoms usually appear within 2 to 5 days after infection and last for about a week. In rare cases, more severe complications such as pneumonia or bronchitis can occur, especially if the dog already suffers from other respiratory diseases or has a weakened immune system.

How is CRCoV diagnosed?

CRCoV is diagnosed by detecting the virus in a sample taken from the dog's nose or throat. For this purpose, a swab is taken and examined in a laboratory. The sample should be taken as soon as possible after the onset of symptoms, as the amount of virus decreases over time.

How is CRCoV treated?

There is no specific treatment for CRCoV. The therapy depends on the symptoms and the general condition of the dog. As a rule, symptomatic treatment is sufficient, which may include the following:

• Rest
• fluid intake
• Fever-reducing medication
• Cough-relieving medication
• Antibiotics for secondary bacterial infections

In severe cases, oxygen therapy or artificial respiration may be necessary.

How can CRCoV be prevented?

The best way to prevent CRCoV is to avoid or minimize contact with infected dogs. The following measures should be observed:

• Keep your dog away from other dogs that show symptoms of respiratory disease.
• Regularly clean and disinfect the objects your dog uses, such as bowls, toys or blankets.
• Wash your hands frequently, especially after handling your dog or other dogs.
• Avoid keeping your dog in confined spaces such as shelters, boarding kennels or dog shows if possible.
• Have your dog regularly examined and vaccinated by a vet.

There is currently no vaccine against CRCoV, but there are vaccines against other respiratory diseases such as kennel cough or parainfluenza that can protect your dog.
