Rabies and canine distemper transmitted from domestic dogs are leading threats to African wild dog population viability, and vaccination programs protect entire packs.
Rabies in wild dogs causes a prolonged, agonizing death. Disease spread through a pack can eliminate an entire social unit within weeks, leaving survivors unable to hunt effectively or care for pups. Vaccination programs protect against this population-level welfare catastrophe and are among the highest-impact interventions available for this endangered species.
