These dogs are trained to detect the whereabouts of endangered species, often in collaboration working with biologists and/or wildlife preservation organisations to validate scientific research. In this detection program most important information is to find the evidence of the live animals. This can be done for instance by detecting scat, fur, feathers, eggs, or specific location identification, etc.
Another area of endangered species detection dogs is to find the remains of the animals. For instance, gall bladder, teeth, skin, rhinoceros horn, ivory, abalone, etc. One of the working areas of these dogs is at borders and transit points, where in some cases they can even find live animals, smuggled from country to country.
