Dog Canine Influenza Outbreak Prevention in Kennels

Canine influenza is a highly contagious respiratory disease that can sweep through kennel populations rapidly without proper biosecurity.

Key Facts

Two strains of canine influenza virus (H3N8 and H3N2) circulate in US dogs; H3N2 is currently dominant
Canine influenza is nearly 100% contagious among exposed susceptible dogs
Incubation period is 2-4 days, meaning dogs shed virus before clinical signs appear
Signs include persistent cough, nasal discharge, and fever lasting 2-3 weeks; pneumonia develops in approximately 20% of cases
Bivalent vaccines against both H3N8 and H3N2 are available and recommended for dogs with social exposure
Two initial doses 2-4 weeks apart are required for vaccination, then annual boosters
Kennels with influenza outbreaks must implement strict quarantine, enhanced disinfection, and temporary closure to new admissions

Welfare Considerations

Canine influenza outbreaks in kennels cause widespread respiratory illness in populations already under confinement stress. Dogs are infectious before symptoms appear, making containment difficult once introduction occurs. Prevention through vaccination of social dogs and robust biosecurity protocols is both more humane for dogs and less disruptive for kennel operations.

What You Can Do

Vaccinate social dogs (those attending boarding, daycare, or dog parks) with bivalent influenza vaccine
Ask kennels and daycares about their influenza vaccination requirements
Isolate any dog showing respiratory signs for at least 10 days after recovery
Inquire about kennel disinfection protocols and outbreak response plans before boarding
Stay informed about local influenza outbreaks through veterinary or shelter networks
