What types of animals does the ADA limit as service animals?

The Americans with Disabilities Act (ADA) specifically defines service animals as only dogs that are individually trained to perform tasks for people with disabilities. However, the ADA also recognizes miniature horses as potential service animals, provided that certain criteria are met, such as size and weight limitations, and the individual must be able to ensure that the horse is housebroken and under control.

This definition underscores the unique role that trained dogs and, in some situations, miniature horses play in assisting individuals with disabilities. The focus is on animals that have been trained to perform specific tasks directly related to the individual's disability, which is not the case for most other domesticated animals. Therefore, the correct choice highlights that the ADA does not consider other animal types, like cats or birds, as service animals, which reinforces the specific and limited nature of this designation.
