Rabies transmitted from domestic dogs is a major threat to endangered African wild dog populations, with vaccination programs protecting wild packs through herd immunity.
Rabies deaths in wild dogs are among the most distressing in wildlife medicine. The neurological disease causes progressive behavioral changes, aggression, and systemic collapse. Small pack sizes mean a single death from rabies may push a pack below functional hunting threshold, causing the survivors to starve. The connection between domestic dog vaccination and wild dog survival is direct and measurable - villages that maintain high dog vaccination coverage around protected areas show lower wild dog rabies rates. Human behavior directly determines wild dog welfare.
