-There is a very special wolf that lives in Africa. They are actually called, the African wild dog, or painted dogs.

These animals live in open woodlands. or in the plains of Africa. Today, however, most of the animals can be found in eastern or southern Africa. These animals are beautiful. They have rounded ears instead of pointed like most dogs, and they have four toes (脚趾) on each of their feet, also a unique characteristic because other dogs have five. Their fur is always different from each other. The fur is usually a combination of black, brown, red, and white, and sometimes even yellow. No wonder they’re called the painted wolf.

The African wild dog is a very social animal. They live in groups and have numbers from five to about twenty. The members of a group are always very close to one another. They communicate in their own language or body language. When someone is very old or sick, the others will help, and they are willing to share the food with elders and with those who are weak, which is what we should learn from.

The family does everything together, from raising young, to sleeping together, to hunting. When they hunt, they work together using team work to kill animals that are larger than them.

They sometimes hunt farm animals. This is unfortunate, because both poachers (偷猎者), and people who own farms shoot the painted dogs who are just trying to survive.

Before, there used to be many large groups throughout the land, but now the African wild dog is very rare. They are also losing their population because of their own loss of habitat thanks to human’s farming and forest cutting.
