A server in Seattle who asks a diner “what disability do you have?” before seating their service dog has already broken the law—twice over, once under federal rules and once under Washington’s own civil rights code. That mistake happens more often than most restaurant owners realize, and it works both ways: handlers sometimes overstate their rights, while staff sometimes underestimate them.
Federal ADA Rules for Service Dogs in Restaurants
The ADA sets the floor for every restaurant in the country, including Washington. Under this law, service animals are expressly distinguished from pets by the function they serve rather than by breed, size, or appearance. A trained dog (Canis lupus familiaris) qualifies as a service animal only when it performs a specific job tied to a person’s disability, not simply because it provides comfort.
Handlers must keep the animal under control at all times. The ADA requires the service animal to be under the complete control of its handler, which could be achieved through the use of a leash, harness, or other tether mechanism. If a leash would interfere with the dog’s work, voice commands or signals are an acceptable substitute.
Restaurants covered by the ADA include virtually every dine-in establishment, since any place that offers services, goods, facilities, or accommodations to the public must allow service dogs. That obligation doesn’t disappear because a restaurant has a “no pets” policy — a legitimate service dog isn’t a pet under the law, and the policy simply doesn’t apply to it.
