African wild dogs (Lycaon pictus), photographed at the Bronx Zoo.
African wild dogs (Lycaon pictus) don't have it easy. Their taste for large mammalian prey puts them in competition with lions and spotted hyenas for both prey and living space, meaning that wild dogs regularly have their kills stolen or are even killed by other predators. In fact, the dogs may even be unintentionally attracting the attention of these other hunters.
