A service dog is easily identified by its?

A service dog is typically identified by a harness that is specifically designed for the role it plays. The harness not only helps to secure the dog and provide control to the handler but often includes specific markings or patches indicating that the dog is a trained service animal. These visual cues are important, as they help the public recognize the dog's working status, which may allow the handler to receive the necessary accommodations or assistance.

While collars and leashes are common for all dogs, they do not uniquely signify that a dog is a service animal, as many pet dogs wear them too. Vests can sometimes be used to identify service dogs, but harnesses are often more practical for working dogs, providing support and better functionality in performing their tasks. Therefore, the harness serves as the most recognizable and functional indicator of a service dog's role.
