Welcome to Service Dog Laws Washington State

Welcome to our service dog laws Washington State guide  and FAQ page, updated for 2023.

Service dog laws in Washington State require that a specially trained service dog (sometimes called assistance dog) be allowed to accompany a person with a disability to all public accommodations and public carriers, with a few exceptions. There are multiple laws that govern the use of these special animals.

In other words, people with disabilities who use service dogs may go wherever the public can go. This includes places such as malls, grocery stores, movie theatres, Airbnb, motels, hotels, trains and buses, taxis, and National Parks. For a related article, check out my guide to Emotional Support Animal Laws in Washington.

Service Animal Definitions

Part of the reason why service dogs can be so confusing is that there are multiple laws around them. Fake service dogs don’t help, either. Here is a summary of the different laws relevant to Washington State and their main purpose in general. Then we will get into the definitions.

In summary:

  • The ADA – Americans with Disabilities Act – is a federal law. It governs the use of service animals when public access rights are concerned. This law is also referred to for housing situations and employment situations with service animals.
  • The FHA – Fair Housing Act – is another federal law that governs the use of service animals – or what is known in this context as “assistance animal” when housing situations are concerned.
  • The ACAA – Air Carrier Access Act – is what is used when service animals will be taken to the skies with their handler. Fully trained service animals are allowed in the cabin of airplanes with their handler as long as they meet the ACAA requirements, and fill out any required paperwork or documents prior to their flight.
  • State-specific service animal laws . Even though we have the federal ADA laws, each individual state may or may not have additional or “state-specific” service dog laws for their own area. Check with individual states for anything that may be different from the ADA laws.
    • A common example is that under the ADA, service dogs in training are not allowed public access rights. However, certain states extend the same rights to service dogs in training, as fully trained animals have
  • Section 504 – is similar to the ADA, and protects the rights of students with disabilities in educational settings.

Who Uses Service Dogs?

…And what do they do?

Service animals are utilized by people who live with a variety of disabilities. Service dogs can help people in many different ways.

Service animals can do so many different tasks. Here are just a few examples:

  • Lead blind people, or people living with low vision
  • Serve as the ears of a deaf or hard of hearing person, alerting them to important sounds
  • They can carry and pick up items
  • To help people with stability and balance issues
  • Provide warnings of impending seizures or low blood sugar
  • Service animals may allow people with anxiety disorders, PTSD or other emotional conditions to function in society by alerting their handlers to avoid anxiety triggers, by recognizing and blocking behaviors, or by stimulating the person to “snap back” to a conscious state.
  • Service dogs can remind people that it is time to take their medication
  • Service dogs can summon help in the case of fainting or a seizure
  • The ways in which people with disabilities use service animals are growing and evolving

Can You Ask for Proof of a Service Dog in Washington State?

No, it’s not permitted under the federal ADA (Americans with Disabilities Act) laws to ask a disabled person for proof their dog is a service dog. In fact, service dogs don’t need to be registered, certified, professionally trained, have a special ID tag or vest, or carry any paperwork or documentation.

Covered entities may not require documentation, such as proof that the animal has been certified, trained, or licensed as a service animal, as a condition for entry.


Businesses and other public entities must not:

  • Ask for personal information about a disability
  • Require proof of certification or any other documentation
  • Ask that the dog demonstrate its work or task

What Qualifies as a Service Dog in Washington State?

In order to qualify as a service dog in Washington state, a dog must be individually trained to perform certain work or tasks for the benefit of somebody who lives with a disability. The work or tasks must be directly related to the person’s disability. This task-training goes above and beyond regular obedience training.

How Do I Make my Dog a Service Dog in Washington State?

To make your dog a service dog in Washington State, you must have a disability and a disability-related need for the animal. Start your service dog training journey, and when your dog is fully trained to act properly in public, and perform specific tasks that mitigate the effect(s) of your disability, then your dog is a service dog, with public access rights.

Even though service animals do not need to be professionally trained by an organization or school, they do need to be trained for their disability. This is not usually an easy task, and many people need help.

It’s also important to note that not just any dog can become a service dog. Dogs are like people and have individual personalities. Some personalities do great with working; others just don’t.

Do Service Dogs Have to Wear a Vest?

No, service dogs do not need to wear a vest, cape, carry or wear identification, or carry documentation. This means that you may not be able to tell if a service dog is in fact a service dog. Many people choose to have their service dog wear a vest because it might make interactions with members of the public easier.

But, people are under no obligation to have their service dog wear a vest or cape. Sometimes the weather is too hot for the animal to wear a vest.

The ADA does not require service animals to wear a vest, ID tag, or specific harness.

What Animals Can Be Service Animals in Washington State?

The only types of animals that can be service animals in Washington state for public access rights, (according to the federal ADA laws as well as service dog laws in Washington), are dogs and miniature horses. It’s worth noting that any breed/kind and size of dog can be used.

Service animals can be other types of animals when it comes to a reasonable request for employment or a housing/residential situation.

Under the federal ADA laws, if a certain breed of dog has been banned from a particular city, county/town, or area, service dogs are exempt.

In other words, even if a city has banned pit bulls, a service dog that happens to be a pit bull must be allowed. It must be permitted to go with its handler anywhere the public can go (with a few exceptions, of course).

Registration & Certification

The truth is that you are not legally required to register or certify a service dog in Washington State or any other state in the U.S. Service dogs are protected under the ADA, Americans with Disabilities Act, and other laws.

In addition, there is no state registration system in place for Washington State. Registration and certification done online from non-government websites do not convey any legal rights under the ADA or the Department of Justice. 

Buying a piece of paper from the internet does not turn a dog into a service dog. Check out our blog Which Service Dog Registry is Legitimate? to learn more about registrations, certifications, and why they are not required.

  • Businesses
  • State governments
  • Local governments

Info For Businesses

It’s obviously important for businesses and other “covered entities” to be aware of service dog laws in Washington State as well as federal laws. If not, they could be accused of discrimination.

The Americans with Disabilities Act prohibits the following:

  • Asking about a disability
  • Requiring medical documentation
  • Requiring a special identification card or training documentation for the dog (or mini horse)
  • Ask that the animal demonstrate its ability to perform the work or task
  • Charge an extra fee because of the animal
  • Segregate the customer with a disability from other customers

Permitted Questions to Ask

If the reason for the service dog is obvious, then businesses and other covered entities may not inquire about the use of the animal.

When it’s not obvious – and many disabilities are invisible – businesses may only ask two questions to someone using a service dog. That’s it.

The questions are:

(1) Is the dog a service animal required because of a disability?

(2) What work or task has the dog been trained to perform?

The Americans with Disabilities Act prohibits discrimination against disabled people in employment situations. In addition, it requires reasonable accommodation at the employee’s request.

Allowing someone with a disability to bring their service animal into the workplace environment is a form of reasonable accommodation.

As with any accommodation request, the employer must consider allowing the use of a service animal at work unless doing so poses an undue hardship, or could disrupt the workplace environment.

Note that an employee may also request that an employer allow a companion animal or emotional support animal in the workplace as an accommodation. Reasonable requests in this situation are not restricted to dogs only.

Psychiatric Service Dogs

Psychiatric service dogs are a type of service dog that perform work or tasks related to psychiatric disabilities.

A few examples of these types of disabilities include:

  • Eating disorders
  • PTSD
  • Anxiety disorders
  • Depression

Here are a few examples of some psychiatric service dog tasks:

  • Providing reminders to take medication at a certain time
  • Service dogs can lay across their handler and apply pressure (Deep Pressure Therapy) during a panic attack, for example
  • Provide tactile stimulation or grounding
  • Interrupting dissociative episodes or other repetitive or problematic behaviors
  • Alerting the handler to rage or other types of strong emotions
  • Interrupting self-harming behaviors
  • Retrieve an item, such as a water bottle and medication for a panic attack
  • Wake someone up from a nightmare
  • Interrupting flashbacks
  • Searching the house or home to ensure it’s clear and safe before the handler enters
  • Providing a “reality check” to help with hallucinations
  • Stabilizing a routine for someone
  • Read more: Psychiatric Service Dog Tasks – 17 Examples

The difference between psychiatric service dogs and emotional support dogs is simple: Psychiatric service dogs are trained to do at least one task for a specific person’s disability, and the task is related to the disability.

Emotional support animals are not task-trained like this and provide comfort and other benefits by their presence alone. Emotional support animals are not service dogs, but they do have some rights when it comes to housing and employment situations.

Training & Service Dogs in Training (SDiT)

Service dogs in Washington State and other states do not need to be trained by a professional service dog training program, or professional trainer (under the ADA laws). But, they do need to be trained by somebody.

Many people train their dogs by themselves or with some help, as many service animal programs have limited resources and long waiting lists.

But, most states have some kind of state laws that allow service animals in training some kind of public access rights.

At this time, only four states do not cover service animals in training under their public accommodation laws.

Washington State is one of the states that at this time does not cover service animals in training. Therefore, the federal ADA laws apply, which state that service dogs must be fully trained before they are allowed public access rights with their human.

Under the ADA, the dog must already be trained before it can be taken into public places. However, some State or local laws cover animals that are still in training.

How to Make Your Dog a Service Dog in Washington State

Stop making that sound so easy! To make your dog a service dog in Washington State, you must have a disability and a disability-related need for the animal. Start your service dog training journey, and work on having your dog learn how to act properly in public, with basic socialization and obedience training, and performing specific tasks that mitigate the effect(s) of your disability. There are different avenues for getting a service animal.

  • You could train the dog by yourself or with some help
  • A dog trainer could help you a lot or a little
  • Sometimes you may be able to find a service animal organization or professional training program. Sometimes these have long waiting lists but it is still a potential option
  • Any combination of these options may be used
  • Since service animals in training in Washington State aren’t provided public access rights, you won’t be able to go into stores and restaurants, but you may be able to find “pet-friendly” stores where you can practice your skills with your animal

Even though service animals do not need to be professionally trained by an organization or school, they do need to be trained for your disability. This is not usually an easy task, and many people need at least some help.

It’s also important to note that not just any dog can become a service dog. Dogs are like people and have individual personalities. Some personalities do great with working; others just don’t. Some dogs truly just can’t focus, don’t listen, or want to only play (or relax) all day.

Service Animal Work or Tasks

The work or tasks done by the animal must be directly related to the person’s disability. The training must be specific to the person using the animal. A service animal is not a pet.

The disability could be:

  • Physical
  • Sensory
  • Psychiatric
  • Intellectual
  • Or another mental disability

The tasks or work done by the animal may include (but are not limited to) the following:

  • Helping to guide someone who is visually impaired or blind
  • Alerting a person who is deaf or hard of hearing
  • Pulling a wheelchair
  • Helping someone with mobility or balance
  • Alerting others and protecting someone having a seizure
  • Retrieving objects
  • Bringing attention to the presence of allergens
  • Providing physical support and help with balance and stability to someone with a mobility disability
  • Helping someone with a psychiatric or neurological disability by preventing or interrupting impulsive or destructive behaviors and/or patterns
  • Reminding someone living with a mental illness to take their prescribed medications
  • Calming someone with post-traumatic stress disorder (PTSD) during an anxiety attack
  • Doing other specific work or performing other special tasks
  • SSigDOG are Sensory Signal Dogs or Social Signal Dogs. These are a service dog that has been trained to assist someone with autism. The service dog typically alerts their human handler to distracting repetitive movements which are common with people living with autism. This allows the person to stop the movement.
  • Psychiatric Service Dogs are a type of service dog that has been trained to perform “work” or “tasks” that help people with psychiatric disabilities to detect the onset of certain, specific episodes and lessen their effects.
  • Seizure Response Dogs are a type of service dogs that are trained to help somebody who has a seizure disorder. How the dog serves the person will depend on individual needs. The seizure response service dog might do a variety of tasks, such as stand guard over their human during a seizure to keep the person safe, or the dog might go and get help.
  • A few dogs have learned to predict a seizure and warn the person in advance to sit down or move to a safe place, but it seems like this can’t reliably be trained in just any dog.

Miniature Horses

Technically speaking, only dogs are service animals under the federal ADA definition for public access rights. Other species of animal, whether that be wild animals or domestic, trained or untrained, are not service animals for the purposes of the ADA.

Service animals may or may not be other types of animals in terms of housing and employment situations. But for now, let’s talk about public access rights.

Even though dogs are the only service animal defined by the ADA, there is a separate provision in the ADA that does cover miniature horses.

What this means is that a miniature horse that has been trained to do work or tasks for a specific disability shall have the same rights as service dogs wherever possible.

Businesses and other covered entities need to provide access for miniature horses whenever possible. Reasonable modifications need to be made in policies, practices, or procedures to permit the use of a miniature horse by a person with a disability.

To determine whether to allow a miniature horse into a specific facility, the business will need to consider the following:

  • The type, size, and weight of the miniature horse and whether the facility can accommodate these features safely
  • Whether the handler has sufficient control of the miniature horse
  • Whether the miniature horse is housebroken
  • Whether the miniature horse’s presence in a specific facility compromises legitimate safety requirements that are necessary for safe operation

Therapy Dogs

Let’s just briefly discuss what therapy dogs are and aren’t, since many people aren’t sure and it can be confusing as there are so many amazing types of dogs in the world! Lucky humans we are indeed.

A therapy dog is not a service dog, and that’s because therapy dogs aren’t trained to do “work or tasks” for an individual’s disability. Plain and simple.

What is a therapy dog
  • Save
Therapy dogs are not considered service dogs.

A therapy dog is usually someone’s pet that enjoys meeting a large number of different people in different settings.

The people who are fortunate enough to spend time with a therapy dog receive great benefits, such as reduced anxiety and added joy.

They often visit places such as schools, hospitals, nursing homes, and other settings where the stress in people may likely be high.

Service Animal Fees

Fees, extra charges, or pet deposits may not be charged for service animals. This is true whether we are talking about the ADA, ACAA, FHA, or Washington State service dog laws.

A service animal is not considered a pet. Someone using a service animal must not be turned away or denied access because of a “no pets” rule or policy.

In the case where a public entity usually charges people for damage caused by an animal or pet, a person with a disability may also be charged for damage caused by their service animal.

Control of Service Animals

  • Service animals must be under control at all times & should not pose a direct threat to the health and safety of others
  • Service animals must comply with state and local animal control laws

Service animals should be kept at a person’s side quietly, unless they are performing a specific task.

Service animals must be leashed, harnessed, or tethered unless this may interfere with the service animals’ work. Or, if a disability prevents using them. In those cases, service animals still need to be controlled through voice, hand signals, or another effective way.


As we’ve already talked about, service animals perform various work or tasks to help someone with a disability to live safely and independently. U.S. Department of Transportation Americans with Disabilities Act regulations define a service animal as “any guide dog, signal dog, or other animal individually trained to work or perform tasks for an individual with a disability, including, but not limited to:

  • Guiding individuals with impaired vision
  • Alerting individuals with impaired hearing to intruders or sounds
  • Providing minimal protection or rescue work
  • Pulling a wheelchair
  • Fetching dropped items

When riding transit, customers with disabilities who use service animals are responsible for maintaining control over their animals (and caring for them) at all times.

Riders are also responsible for knowing the best way to board and position their service animal on the vehicle, especially if the service animal may be required to provide assistance (“tasking”) during the transit trip.

Service animals may not block aisles or exits.

According to ADA regulations, every transportation employee or operator who serves people with disabilities needs to be trained so that they know how to provide non-discriminatory service in an appropriate and respectful way.

When serving passengers who are blind, operators should:

  • Identify themselves
  • Speak directly to the customer instead of through a companion
  • Use specifics such as “there are five boarding steps and a 10-inch drop to the curb” when giving directions

Transit agencies should be aware of the following rules under ADA:

  • Operators must allow all service animals on board
  • Operators may not ask for proof of service animal, certification or of the customer’s disability
  • Operators may not require a person traveling with a service animal to sit in a particular seat on the vehicle or charge a cleaning fee for customers who bring service animals onto the vehicle, unless the animal causes damage
