Anti-poaching dog patrol training session. Dogs working with their handlers are trained in anti-poaching methods such as the detection of rhino horn, elephant tusks, snares, animal carcasses or remnants, residual animal scents in vehicles and buildings. They also track wounded animals, and can have security roles as attack dogs. Photographed in July 2015, in Mkhaya Game Reserve, part of the Big Game Parks network in Swaziland.
