High Quality Content by WIKIPEDIA articles! A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. They may be close members of the family, such as guide or service dogs, or they may be animals trained strictly to perform a job, such as logging elephants. They may also be used for milk, a job that requires human training to encourage the animal to cooperate. Some, at the end of their working lives, may also be used for meat or other products such as leather. Such animals are sometimes called draft animals or beasts of burden.
