Service dog or companion
Federal disability law reserves the term service animal for dogs that have learned, through individual training, to carry out work linked to their owner's disability. If the condition behind that work is a mental health one, the dog is commonly called a psychiatric service dog.
Companionship by itself, however comforting, isn't a trained job in the legal sense. That single distinction separates a PSD from an emotional support animal. Typical PSD jobs look like this:
- Leaning its full weight into you on cue when anxiety spikes
- Nudging or pawing to break a loop of skin picking or other harmful habits
- Rousing you when a PTSD nightmare begins
- Steering you out of a crowd toward a calmer spot
- Carrying over your medication or phone when you can't get up
Using the letter for housing
Renting is where this letter earns its keep. Federal fair housing law obliges landlords to adjust their rules for people with disabilities, and allowing a trained dog in a no-pets building is a textbook adjustment. If neither your condition nor the dog's role is plain to see, the property manager can request trustworthy proof. A signed note from a clinician who actually assessed you is the standard answer.
In its enforcement memo dated May 22, 2026, HUD told investigators to presume that requests for task-trained animals are reasonable, while dogs and other animals without such training get a closer, individual look. Dorm and campus apartment offices are bound by the same fair housing duties, alongside their own request forms.
Your landlord isn't entitled to a diagnosis or a stack of medical records. And if the dog chews a door frame, the repair bill is still yours.
Public places need no paperwork
Restaurants, shops, hotels, clinics and similar venues follow the federal disability law's own access rules, and those rules don't involve documents. If what the dog does isn't apparent, employees get exactly two questions: is the dog needed because of a disability, and which job has it learned to do?
Beyond that, they can't insist on paperwork, a badge, a harness label or watching the dog perform. They can, though, send away a dog that's acting up and isn't brought back under control, or one that has accidents indoors, so solid manners matter.
Websites selling registrations, numbered certificates or ID cards are selling nothing the law recognizes. Neither Washington nor any state maintains a service dog list.
Taking your PSD on a plane
Airline rules written by the Transportation Department (14 CFR Part 382) make carriers accept trained service dogs in the cabin. Rather than a clinician's note, an airline can hand you its version of the DOT Service Animal Air Transportation Form, on which you yourself vouch for the dog's training, health and conduct; a second DOT form covers bathroom breaks on trips lasting eight hours or longer.
Because you sign those forms personally, our letter isn't part of the boarding process, though some travelers like to keep a copy in their bag. Emotional support animals fall outside these protections, and most carriers now treat them as pets.
Booking your PSD assessment
Pick a time online; reserving costs nothing. On a short video or phone call, a licensed clinician asks how your symptoms show up day to day and which jobs your dog handles for you.
When the clinician concludes a letter is warranted, a signed PDF usually reaches your inbox that day. It shows the clinician's full name, credential, license number, licensing state and the date signed, so anyone can verify it. One or two dogs cost $149 in total; when no letter is issued, you pay nothing.
Calls are only scheduled where our clinicians hold a license, and the booking form checks your state first.
PSD letter or ESA letter
Choose the PSD route only when your dog genuinely performs learned jobs tied to your condition. A dog that helps simply by staying close is still doing something important, but legally that's an emotional support animal, and our ESA letter is the accurate fit.
A growing number of states fine anyone who presents a pet as a working service dog, and fake claims erode trust for handlers whose dogs are working. Not sure which side you fall on? The clinician will help sort it out on the call. For a mental health crisis, call or text 988, and dial 911 for emergencies.

| Online registries | No | Not recognized by any law |
Frequently asked questions
What does a PSD letter say?
A licensed clinician who assessed you confirms that a mental health condition substantially limits you and that your dog's trained jobs ease it. People mostly use it with landlords and campus housing offices.
Will a store ask to see my PSD letter?
It shouldn't. Staff are limited to two questions about the dog's role and its trained job; demanding papers isn't allowed under federal disability law.
When can my landlord request one?
When neither your condition nor the dog's job is apparent, the landlord can ask for trustworthy proof. A clinician's signed letter is the normal way people provide it.
Does the letter certify my dog?
No. Training is the qualifier here. The letter speaks only to your need; it doesn't register, certify or train anything.
Will my airline want the letter?
Usually not. Carriers can ask for DOT forms that you sign about your dog, but they can't make a clinician's note a condition of boarding.
What does it cost?
$149, which covers one or two dogs. Reserving a time is free, and the charge applies only once a letter is issued.
My dog hasn't learned any tasks. Now what?
Then your dog is most likely an emotional support animal. Our ESA letter may suit you better, and your clinician will walk through how the two differ during the call.
