Service dog etiquette: the do's and don'ts

Service dog etiquette: do

• Do speak to the handler, not the dog. That is the first rule on the Guide Dog Foundation for the Blind's etiquette list.
• Do ask before you pet, and accept no as a complete answer. More in can you pet a service dog?
• Do give the team room in aisles, doorways, lines and elevators.
• Do keep your own dog back unless you have asked the handler first.
• Do offer help the ordinary way, by asking "Would you like a hand?" and following the answer.
• Do respect "do not pet" gear on any dog, service dog or not. The owner is telling you what their dog needs.

Service dog etiquette: don't

• Don't touch, talk to, feed or otherwise distract the dog. The Guide Dog Foundation asks people not to do any of these "while he is wearing his harness or vest."
• Don't give the dog commands. "Allow the handler to do so."
• Don't whistle, make kissing noises, bark at it or call its name, even as a joke.
• Don't offer food, including "just a little" from your plate. "Never give the dog table scraps."
• Don't grab the handler or the harness. The Guide Dog Foundation: "Never attempt to grab or steer the person while the dog is guiding or attempt to hold the dog's harness."
• Don't quiz the handler. Covered next.

Should you talk to a service dog handler?

Yes, the way you would talk to anyone. Handlers are people out running errands, not a public exhibit, so lead with the person, not the dog. Questions about the dog's name or breed are usually fine if the moment is right, and a handler who is busy may keep it short.

What to avoid is anything about their health. Atlas Assistance Dogs puts it plainly: "Never pry into a handler's privacy with questions about their disability," and skip questions like "do you really need that dog?" Even a business may not ask about a person's disability under the ADA; a stranger certainly has no reason to.

What to do if a service dog approaches you without its handler

This is the one exception to "ignore the dog." A service dog that comes up to you on its own, nudging you or barking, with no person in sight, may be trained to get help. Atlas Assistance Dogs' advice is direct: "Follow the service dog, who will take you to their handler in need of help."

1. Do not shoo the dog away.
2. Follow it, calmly, and let it lead.
3. If you find the handler hurt, unresponsive or in distress, call emergency services and stay with them.
4. If the dog is alone and loose with no handler to be found, treat it as you would any lost dog in a vest. A tag or card with an emergency contact, if it has one, is the quickest way to reach its family.

That last point is one reason some handlers keep an emergency contact on the dog's collar or an ID card; our voluntary registry exists partly for that. It is a practical record, not a legal document.

Photographing service dogs

Ask first. A photo of a dog in a vest is also a photo of a person with a disability, often in a moment they did not choose to share. Pointing a phone at the dog, crouching down or calling it to look at you can also distract it. If you would like a picture, ask the handler, and accept no just as easily as you would for petting.

If a service dog barks or seems to misbehave

Give the handler space to handle it. Dogs are not robots, and a well-trained dog can still react to a dropped tray or a dog lunging at it. DOJ's guidance says a service dog should not bark repeatedly in quiet places, but "if a dog barks just once, or barks because someone has provoked it, this would not mean that the dog is out of control." And some trained tasks look like odd behavior if you do not know what you are seeing: pawing, nudging, leaning on the handler or pulling them away may be the dog doing its job.

Service dog etiquette for businesses and staff

For staff, most of the etiquette is written into law:

• If the dog's job is not obvious, ask only the two questions: is the dog required because of a disability, and what task is it trained to perform. Nothing else.
• Never ask for an ID card, certificate, vest, registration or demonstration. No document is required under the ADA.
• Do not seat the customer somewhere worse, add a pet fee, or point to another customer's allergy or fear. DOJ says allergies and fear of dogs "are not valid reasons for denying access or refusing service."
• Do not pet or feed the dog yourself, however friendly you mean to be.
• If a dog is genuinely out of control and the handler does not take effective action, or it is not housebroken, you may ask for it to be removed, and must still offer to serve the customer.

Etiquette for other dog owners

A pet that rushes a working dog can break its focus in seconds, and it is a problem you can prevent completely. Atlas Assistance Dogs says: "Never allow your dog to approach or attempt to interact with a service dog." The Guide Dog Foundation asks owners to "make sure not to allow your pets to challenge or intimidate a guide dog."

Keep your dog on a short leash as you pass, cross the aisle or street if yours is excitable, and do not let dogs sniff noses unless the handler has said yes. Some states treat this seriously: California makes it an offense to let your dog injure a service dog (Penal Code 600.2), and Montana makes it a misdemeanor to negligently let your dog interfere with one (MCA 45-8-227).

If your own dog is the one that needs space from people and other dogs, gear helps others give it: see reactive dog vests and gear.
