The African wild dog is one of the most endangered mammals in the world. Most of the population is concentrated in southern Africa and the southern part of East Africa. Wilds dogs live and hunt in packs of up to 20. They can live between 10 and 12 years. Currently only about 6,600 remain in the wild. The main causes of a shrinking population are due to habitat loss caused by human overpopulation, poaching, diseases, and threats from predators such as lions and hyenas.
