Do service dogs need to be harnessed? If so, does it need to say “service dog” on it?

ANSWER: Under the ADA, service animals must be harnessed, leashed, or tethered, unless these devices interfere with the service animal’s work or the individual’s disability prevents using these devices. In this case, the individual must maintain control of the animal through voice, signal, or other effective controls. Staff cannot ask about the person’s disability, require medical documentation, require a special identification card or training documentation for the dog, or ask that the dog demonstrate its ability to perform the work or task. The service animal does not need to have an identification on the animal such as a collar, leash, or vest.
