African wild dogs are capable swimmers despite lacking specialized aquatic adaptations.
Satellite collar data from the Zambezi region have recorded African wild dogs crossing river channels approaching one kilometer in width. Such crossings often occur at night when temperatures are lower and human disturbance minimal. Despite not being aquatic specialists, wild dogs can swim effectively when motivated by prey movement or territorial shifts. River barriers that restrict other terrestrial predators do not fully deter them. These crossings expose individuals to crocodile predation and strong currents. Movement data confirm repeated successful traversals during seasonal shifts. Water becomes an obstacle negotiated rather than avoided.

At the ecosystem level, river crossings expand functional territory size and enable genetic exchange between subpopulations. Hydrological changes can either facilitate or restrict these movements depending on flood intensity. Infrastructure such as dams and human river activity may alter crossing behavior. Conservation planning must account for aquatic barriers alongside terrestrial ones. A predator’s range is shaped by currents as well as grasslands.
For dispersing coalitions, nighttime swimming represents high-risk navigation. Packs must regroup on unfamiliar banks and resume coordinated movement quickly. Researchers analyzing collar tracks observe abrupt linear trajectories across water features. The willingness to cross wide rivers underscores extreme mobility requirements. Boundaries drawn in blue ink on maps rarely confine them. Survival includes swimming through darkness.
