Short answer
A psychiatric service task is a specific action a dog is trained to perform because of your disability, such as calming you during an anxiety attack, reminding you to take prescribed medication, or checking a room before you enter. Comfort from the dog's presence alone is not a task under the ADA. In housing, HUD's May 2026 memo presumes that a request to waive pet rules is reasonable for an animal trained to perform disability-related tasks. An untrained emotional support animal doesn't get that presumption.
People often use "psychiatric service dog" and "emotional support animal" as if they mean the same thing. Under federal law they don't. The difference is the training, and the tasks are where that training shows. This guide lists the examples that the ADA and federal housing guidance actually name, and explains where the examples stop.
What counts as a psychiatric service task?
Under the ADA, a service animal is a dog that is individually trained to do work or perform tasks for a person with a disability. The definition includes psychiatric and other mental disabilities. HUD's May 2026 memo quotes the same definition, so the test is the same whether you're at a store or applying for an apartment.
The key word is trained. A dog that is calm around you, sleeps near your bed or makes you feel safer is an emotional support animal. The ADA's FAQ draws the line this way: if a dog has been trained to sense that an anxiety attack is about to happen and take a specific action to help avoid it or lessen its impact, that can qualify. If the dog's mere presence provides comfort, it doesn't.
Tasks for PTSD
The ADA's list of examples includes "calming a person with Post Traumatic Stress Disorder (PTSD) during an anxiety attack." That is the most direct example in the federal materials.
The ADA's FAQ gives a second example. A returning veteran with PTSD who has great difficulty entering unfamiliar spaces may have a dog that is trained to enter a space first, check that no threats are there, then come back and signal that it is safe to enter. The task is specific, it is trained, and it relates directly to the disability, which is what makes it count.
Tasks for anxiety and panic attacks
Many people look into a psychiatric service dog for panic attacks or severe anxiety. The federal materials don't list step-by-step techniques, so the question is always the same: does the dog perform a trained action in response to your symptoms?
The ADA's FAQ example is the one to remember. The dog is trained to notice an attack starting and to take a specific action that helps avoid the attack or lessens its impact. Techniques such as leaning or lying across the handler for deep pressure, or guiding the handler to an exit, are common in psychiatric service dog training. They are not named examples in the ADA materials, so they count only when the dog has been trained to do them in response to your symptoms.
Tasks for depression and medication reminders
The ADA's FAQ gives a clear depression example: a person with depression may have a dog that is trained to remind them to take their medication. The ADA's own list of examples also includes reminding a person with mental illness to take prescribed medications.
A reminder works best when it is specific. Write down the time, the medication and the action the dog takes, such as nudging you at a set hour or bringing you a phone or a glass of water. A vague "keeps me company" is not a task.
Tasks for autism
The ADA's FAQ includes an example for autism: a dog trained to keep a child with autism from wandering away. The example shows how a task can be built around a safety problem rather than a feeling.
What if your condition isn't on this list?
The ADA's examples are illustrations, not a complete list. None of the examples in the federal materials we reviewed name tasks for bipolar disorder, OCD or ADHD, and that doesn't mean a dog can't be trained for them. The test is the same for every condition: can you describe the symptom, the cue the dog responds to, and the action it takes?
If you're considering a dog for bipolar disorder, our guide on emotional support animals for bipolar disorder explains the planning questions to answer first.
How trained tasks change a housing request
In housing, the task list matters more than it used to. HUD's May 22, 2026 memo says that for complaints about animal-related accommodations, HUD will find reasonable cause and recommend charges only in cases involving animals trained to provide disability-related assistance. It says requests to waive pet policies for animals trained to perform specific disability-related services are presumptively reasonable. It also says requests to waive pet policies for untrained ESAs are not.
That is a federal enforcement position, not a new law. The Fair Housing Act still requires landlords to consider reasonable accommodation requests, and state laws still apply. But if your dog performs trained tasks, you have a clearer basis to point to. Our guide to HUD's 2026 changes covers the timeline and what didn't change.
Do you need certificates or a written task list?
Under the ADA, no. A service dog doesn't need a certificate, a registration number or proof of training. Businesses can ask only two questions when a dog's status isn't obvious: whether the dog is required because of a disability, and what work or task it has been trained to perform. They can't require documentation or ask the dog to demonstrate the task. Online registries that sell certificates don't create any rights under the ADA, and the Justice Department doesn't recognize them as proof.
Housing works differently. When a disability isn't obvious, a landlord may request reliable information or documentation of the disability-related need behind your request, as the 2004 HUD and Justice Department joint statement explains. A letter from a licensed mental health professional, and a written description of what your dog is trained to do, are the clearest way to provide that information. Our PSD letter documents the need. It doesn't certify the dog.
How to write down your dog's tasks
Keep a simple table with one row per task. For each row, write the symptom, the cue the dog responds to, the action it takes, how often it happens, and where you practise it. A task that works at home but fails in a crowded store is still in training. Keep the list with your PSD letter.
How many tasks does a dog need?
The ADA doesn't set a number. A dog needs at least one trained task that is directly related to your disability. A longer list is not better if the tasks are not reliable. Start with the symptom that affects you most, train it well, and add tasks only after the first one works in public.
Frequently asked questions
Is a written task list required by law?
No federal rule requires a written task list for a service dog in public places. In housing, a landlord may ask for reliable information about a disability-related need when the disability isn't obvious. A letter from a licensed mental health professional and a clear description of the dog's trained tasks are the usual way to show it.
Does a psychiatric service dog need professional training?
No. The ADA says people with disabilities have the right to train their own dogs and aren't required to use a professional program. The dog does have to be fully trained before it goes into public places.
Can an emotional support animal become a psychiatric service dog?
Only if it is trained to perform a specific task that is related to your disability. Comfort from being present doesn't count, however long the animal has lived with you.
Can a trained animal other than a dog qualify?
Under the ADA, only dogs count as service animals in public places. HUD's May 2026 memo refers to animals trained to provide disability-related assistance in housing, not only dogs. Check your state's law for specifics.
Does the ADA let a business ask about my disability?
No. Staff can ask only whether the dog is required because of a disability and what task it has been trained to perform. They can't ask about your diagnosis or require medical documentation.
Can a business ask my dog to perform its task?
Under the ADA, no. When a dog's status isn't obvious, staff can't require the dog to demonstrate its ability to perform the work or task.

Find out whether you qualify for a PSD letter
Answer a few questions and a mental health professional licensed in your state reviews your assessment. If you're approved, your psychiatric service dog letter arrives as a PDF, typically within 24 to 48 hours of your evaluation.* $139 one-time, or $199 for the ESA and PSD letters together. Full refund if you're not approved.
*Arkansas, California, Iowa, Louisiana and Montana require a 30-day client–provider relationship before a letter can be issued, so the letter issues after day 30.
