Service animal in the context of "Draft animal"

A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks. Some are used for their physical strength (e.g. oxen and draft horses) or for transportation (e.g. riding horses and camels), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons, and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or leather.

The history of working animals may predate agriculture as dogs were used by hunter-gatherer ancestors; around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants.

An emotional support animal (ESA) is an animal that provides support to individuals with a mental health or psychiatric disability. Emotional support animals are not required to be trained. Any animal that provides support, comfort, or aid, to an individual through companionship, unconditional positive regard, and affection may be regarded as an emotional support animal.

In the United States, emotional support animals are not recognized as service animals under the Americans with Disabilities Act. Service animals are trained to perform specific tasks such as helping a blind person navigate. People with mental health disabilities who possess an emotional support animal may be exempt from certain federal housing and travel rules. To receive these exemptions, the handler must meet the federal definition of disabled, and the emotional support animal must help alleviate the symptoms or effects of the disability. The individual may need to present a letter from a certified healthcare provider, stating that the emotional support animal is needed for their mental health.
