A hearing dog is a specific type of assistance dog specifically selected and trained to assist people who are deaf or hard of hearing by alerting their handler to important sounds, such as doorbells, smoke alarms, ringing telephones, or alarm clocks. They may also work outside the home, alerting to such sounds such as sirens, forklifts and a person calling the handler's name.
Dogs that may become hearing dogs are tested for proper temperament, sound reactivity, and willingness to work. After passing initial screenings, they are trained in basic obedience and exposed to things they will face in public such as elevators, shopping carts, and different types of people. Only after that period of socializing are they trained in sound alerting.
Hearing dogs may be trained professionally in as little as three months, though many are trained for closer to a year. Generally, training involves getting the dog to recognize a particular sound and then physically alert or lead their handler to the source. They may also be taught to physically alert to and/or lead away from a sound, such as in the case of a fire alarm.
While many hearing dogs are professionally trained, as described and stated above, it is important to note that this is not a legal requirement and there are deaf or hearing-impaired individuals who successfully, and legally, undertake the challenge of training their own hearing dogs.
In the United States, Title III of the Americans with Disabilities Act of 1990 allows hearing dogs, along with guide and service dogs, access to anywhere the general public is permitted. The Fair Housing Act allows hearing dogs as well as other types of assistance animals to visit and live in housing developments that have no pets policies. The U.S. Department of Housing and Urban Development's Office of Fair Housing and Equal Opportunity investigates complaints from the public alleging denials of reasonable accommodation requests involving assistance animals. Some state laws also provide access protection or additional guidelines, such as fines or criminal penalties for interfering with or denying access to a hearing dog team.
Hearing dogs often wear a bright orange leash and collar to identify them. Some also wear a cape or jacket, which may or may not be orange. Although, in the United States, a hearing, signal, guide, or any other service dog is not legally required to have or wear any badge, leash, collar, or any other identifying item.
In Australia, hearing dogs are trained through the Lions Club International of Australia. They wear a bright orange leash, collar and harness to identify them, and carry with them an issued ID. They are permitted by law access with their handler anywhere that is open to members of the public.
Labradors, golden retrievers, German shepherds, Doberman pinschers, rottweilers and collies are selected as hearing dogs
