Canine influenza outbreaks in kennels and shelters cause significant welfare harm through respiratory illness, shelter closure, and disruption to adoption programs that affects thousands of animals.
Canine influenza outbreaks in shelters create cascading welfare problems: sick dogs suffer respiratory illness, quarantine protocols confine healthy dogs who cannot be adopted, and shelter resources are diverted from enrichment to disease management. Prevention through vaccination of dogs attending high-risk venues and rapid outbreak response protocols minimize the welfare impact on shelter populations. Shelter workers who recognize influenza signs early and implement quarantine promptly protect the majority of residents from exposure.
