Assistance Dogs vs Pet Dogs: 5 Common Myths When You Meet One at a Cafe

At a dog-friendly cafe, you may notice a dog in a harness or vest lying quietly at someone's feet. You might want to greet it as you would your own dog, but it may be an assistance dog at work.

In Japan, assistance dogs are the guide dogs, service dogs and hearing dogs defined by the Act on Assistance Dogs for Persons with Physical Disabilities. Whether a pet dog may enter a venue depends on that venue's rules (our summary). On the other hand, under the Act, venues used by many members of the public generally may not refuse assistance dogs, even where pets are not allowed.

This article checks five myths that dog owners often hold, using materials from the Ministry of Health, Labour and Welfare and local governments (as of October 2026). By the end, you will know what you and your dog should do when you meet an assistance dog at a venue.

Myth 1: "Assistance dog means guide dog" — there are three types

Assistance dogs are not only guide dogs. The Act defines three types as assistance dogs: guide dogs, service dogs and hearing dogs. Gov-Online, the government's public information site, describes their work as follows.

According to the Ministry of Health, Labour and Welfare, as of April 2026 there were 744 working guide dogs, 54 service dogs and 51 hearing dogs. There are far fewer service dogs and hearing dogs than guide dogs. Knowing that there are assistance dogs besides guide dogs makes it easier to notice them at a venue.

Myth 2: "A well-trained dog is the same as an assistance dog" — only certified dogs wearing a sign

However well trained a pet dog may be, it is not treated the same as an assistance dog. Assistance dogs are certified under the Act and have received special training.

When using venues, the law requires the person the dog works with (called the "user" in Japan) to put a sign on the dog showing that it is an assistance dog. Users must also carry documents showing that the dog poses no public health risk, and show them when asked. Guide dogs wear a white or yellow harness, and service and hearing dogs wear a vest, each showing the type of dog and a certification number.

The Ministry explains that if a dog said to be an assistance dog does not have the required sign, the venue has no obligation to admit it. Maebashi City (Gunma Prefecture) also says in its Q&A that therapy dogs are not assistance dogs. Pet dogs follow each venue's own rules (our summary).

Myth 3: "Assistance dogs can only enter dog-friendly places" — even places that ban pets generally may not refuse them

Venues used by many members of the public generally may not refuse a person with an assistance dog, whether or not they allow dogs. Article 9 of the Act says so. A guidebook for restaurants published on the Ministry's website also explains that admitting them is mandatory.

There are exceptions when there is an unavoidable reason, such as a risk of serious damage to the facility or to other users. The same guidebook notes that neither the Food Sanitation Act nor local ordinances prohibit assistance dogs from entering restaurants.

Users look after their dogs' health, hygiene and behavior with guidance from a veterinarian. If you see an assistance dog at a place that does not allow pets, knowing that a separate set of rules applies will spare you any surprise.

Myth 4: "It's cute, so it's fine to talk to it" — speak to the person, not the dog

With an assistance dog at work, the etiquette is not to distract it by talking to it, staring at it or touching it. A Ministry leaflet explains that this is because the user's instructions are very important to the dog. You are also asked not to give it food.

Osaka Prefecture asks people not to give assistance dogs water as well as food. When you give your own dog water or treats at a cafe, do not offer any to the assistance dog.

On the other hand, the person you can talk to is the user. The Ministry asks that if a user seems to be having trouble, you offer help by speaking or writing, for example, "Can I help you with anything?" Remember: talk to the person, not the dog.

Myth 5: "Dogs can say hello to each other" — keep your dog away and settled at your feet

Avoid letting your dog approach an assistance dog to say hello. The Ministry asks people not to distract assistance dogs. We think letting your dog go over to sniff could also distract the assistance dog.

A guide dog leaflet posted on Shimane Prefecture's website includes a request to people walking pet dogs. It asks them to let others know they have a dog with them. At a venue, too, if you are seated nearby, let the user know, "I have a dog with me." With a hearing dog user, choose a way that gets through, such as a note or gestures.

When using venues, the Act requires users to manage their assistance dogs' behavior well so that they do not bother others. It is not a rule written for pet owners, but likewise, as a dog owner, it is your job to hold the leash short and keep your dog settled at your feet.

Assistance dogs and pet dogs at a glance

Assistance dogs and pet dogs differ in the basis of their rules, admission to venues and how others should behave around them. It helps to check the table before you go out.

When you meet an assistance dog at a venue, follow these steps.

1. Hold your dog's leash short and keep it away from the assistance dog
2. Do not talk to, stare at or touch the assistance dog
3. If you are seated nearby, let the user know you have a dog with you (by voice, a note or other means)
4. If the user seems to need help, ask, "Can I help you with anything?"
