Canine Influenza: Respiratory Welfare and Prevention

Key Welfare Facts

Canine influenza is caused by H3N8 and H3N2 influenza viruses, both capable of causing respiratory disease in dogs.
Most dogs show mild disease with nasal discharge and cough, but 5-8% develop severe pneumonia.
High contagion rates mean outbreak settings including kennels and dog parks can cause rapid spread.
Severely affected dogs experience significant respiratory compromise, fever, and discomfort lasting 2-3 weeks.
Vaccination with bivalent CIV vaccines is recommended for dogs at high risk of exposure in group settings.
Outbreak containment requires isolation of affected animals and thorough environmental decontamination.

Welfare Assessment

Canine influenza causes significant welfare compromise in severe cases and spreads rapidly in social dog populations. Vaccination of at-risk dogs, prompt isolation of sick animals, and good kennel hygiene are the primary preventive welfare interventions.

What You Can Do

Vaccinate dogs regularly attending boarding, daycare, or dog shows with bivalent CIV vaccine
Isolate dogs showing respiratory signs immediately from other dogs
Inform boarding facilities of any recent illness before housing dogs
Seek veterinary assessment promptly for dogs with persistent cough or fever
