The African wild dog is a hunting dog and as such picks off the weaker animals in the wild helping to restore a natural balance in life. Unlike other dogs they have four toes on their feet instead of five. Packs are typically composed of related females, related males, and pups.

However, because only the alpha male and female have puppies in a pack, they usually don't have puppies have puppies until later on or not at all. In a serendipitous finding, captive African wild dogs appeared to display significant seasonal change in male reproduction. As a result 80% of their hunts end successfully, compared to, say, lions at 10%.
