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 him from using these devices. Individuals who cannot use such devices must maintain control of the animal through voice, signal, or other effective controls. Businesses may exclude service animals only if 1) the dog is out of control and the handler cannot or does not regain control; or 2) the dog is not housebroken. If a service animal is excluded, the individual must be allowed to enter the business without the service.
