Often businesses such as stores, restaurants, hotels, or theaters have policies that can exclude people with disabilities. For example, a “no pets” policy may result in staff excluding people with disabilities who use dogs as service animals.

Under the ADA’s revised regulations, the definition of “service animal” is limited to a dog that is individually trained to do work or perform tasks for an individual with a disability. The task(s) performed.
