Premise: A working animal is an animal , usually domesticated , that is kept by humans and trained to perform tasks . Most working animals are either service animals or draft animals . Working animals are usually raised on farms , though some are still captured from the wild , such as dolphins and some Asian elephants . On rare occasions , wild animals may be not only tamed , but trained to perform work , though often solely for novelty or entertainment purposes , as such animals tend to lack the traits of trustworthiness and mild temper that characterize the true domesticated working animal .
Hypothesis: A working animal is wild only.
