What Are Assistance Dogs?
In Japan, under the "Physical Disability Assistance Dog Law," three types of dogs are officially recognized as assistance dogs: guide dogs, service dogs, and hearing dogs. All of them receive special training to support the independence and social participation of people with disabilities, and are legally permitted to accompany their handlers in public facilities, transportation, workplaces, restaurants, and other locations. They play a fundamentally different social role than ordinary pet dogs, and handlers are required to understand this correctly.
Refusing to allow someone using an assistance dog to bring their dog for reasons such as "I'm uncomfortable with dogs" or "I have allergies" can constitute a legal violation. Nevertheless, even members of the general public who have no direct involvement should have a correct understanding of assistance dogs—doing so is important for deepening societal understanding as a whole.
The Work and Current Status of Guide Dogs
Guide dogs are trained to lead people with visual impairments safely as they move about. They are thoroughly trained to avoid obstacles, stop at steps and intersections, and advance only when their handler gives the command "Go."
A crucial point is that guide dogs "will not move without instruction." Rather than "pulling" a person who cannot see, the guide dog's role is to assist the handler's judgment. Since they cannot recognize traffic light colors, the handler themselves must judge based on sounds and traffic flow to decide whether to proceed.
Currently, approximately 800 guide dogs are working in Japan (as of 2023). This represents a decline compared to the peak of over 1,100, which is attributed to high training costs and a shortage of training institutions and personnel. It is not uncommon for prospective handlers to wait several years from applying for training until they actually receive their guide dog.
The Role and Training of Service Dogs
Service dogs support people with physical disabilities in their daily lives and have an exceptionally wide range of capabilities. They learn to retrieve dropped items, open doors, operate light switches, assist in pulling wheelchairs, and call for help in emergencies—mastering these diverse tasks.
Training typically takes 2 to 3 years. It requires considerable concentration and learning on the dog's part, and not all dogs can become service dogs. Candidate dogs that are assessed and deemed unsuitable may be placed in private homes as "career-change dogs."
The number of service dogs is even smaller than guide dogs, numbering only around 60 as of 2023. Supply chronically falls short of demand, and low public awareness is another challenge.
How Hearing Dogs Work and Their Contribution to Daily Life
Hearing dogs are trained to alert people with hearing impairments to sounds. They detect sounds necessary for daily living—such as doorbell chimes, telephone rings, crying babies, timer alerts, and fire alarm warnings—by touching their handler's body and leading them to the sound's source.
Behind this seemingly simple behavior of "hearing and alerting to sounds" lies hundreds of hours of careful training. Particularly for fire alarm sounds, hearing dogs are trained to perform a special action—lying down flat—which prompts their handler to ensure an escape route.
Hearing dogs are the least numerous of the three types of assistance dogs, with fewer than 70 as of 2023. Since hearing impairment is not visually apparent, there are cases where difficulty arises in gaining understanding and acceptance of assistance dog accompaniment.
Etiquette Every Pet Owner Should Know
When you see an assistance dog, there are behaviors the general public should be mindful of. Most importantly, do not touch or speak to the dog without permission. Assistance dogs are working, and distractions can jeopardize their handler's safety. When children try to approach saying "how cute," adults must intervene and stop them first.
Giving food is strictly forbidden. Weight management and health care are directly linked to job performance, so extra food is strictly limited. Also, avoid calling out sounds like "woof" or trying to call the dog with your hand.
Speaking to the handler is not a problem in itself, but it is proper etiquette to ask permission first. While it is natural to be curious about the assistance dog, prioritizing the handler's wishes and the dog's concentration above all else is paramount.
Coexisting with Your Own Pet Dog
When pet dog owners encounter someone with an assistance dog, certain considerations are necessary. Even if your dog has a friendly temperament, avoid allowing it to approach the assistance dog. Although assistance dogs are trained to remain calm and not bark even when unfamiliar dogs approach them suddenly, this still disrupts the handler's concentration.
Keep your dog on a short leash and maintain distance from the assistance dog. If your dog tries to approach the assistance dog while passing, firmly hold it back. This is both a matter of courtesy toward the assistance dog and consideration for those who need it.
This can also be an opportunity to teach children about assistance dogs. By explaining that "the dog is working, so let's not call out to it," you can naturally foster children's understanding of social rules and diversity.
