Reviews each evaluation and issues HealifyNow's emotional support animal and psychiatric service dog letters.
Documentation for your trained psychiatric service dog from a licensed clinician who actually evaluates you — for housing requests and travel, not a diploma-mill certificate.
A psychiatric service dog is individually trained to perform tasks that help with a psychiatric disability. A PSD letter is documentation from a licensed clinician confirming that disability and how the dog's tasks help.
A licensed clinician makes the final decision after a real evaluation.
Such as PTSD, severe anxiety, panic disorder, major depression, OCD or bipolar disorder.
The dog is individually trained to perform tasks that mitigate your disability, or is actively in training.
Your condition substantially limits major life activities such as work, sleep or social functioning.
We never issue letters without an evaluation. The clinician's role is to assess, not to rubber-stamp.
Not sure your dog qualifies? If your dog provides comfort but isn't task-trained, an ESA letter may be the right fit.
Start your evaluationTell us about yourself, your psychiatric history, your dog, and the tasks it performs or is being trained to perform.
Choose a phone or video call with one of our letter clinicians at a time that suits you.
An honest conversation about your mental health, your service dog, and how its tasks help with your symptoms.
If you qualify, your letter is issued on the clinician's letterhead with their license details for verification.
If you don't qualify, the clinician will tell you — and you aren't charged. Honest evaluations protect you and the legitimacy of the service dog community. Letters are usually renewed yearly for ongoing housing documentation.
Same price in every state. Free to book, and you only pay if the clinician approves your letter.

“Lost my prior therapist when she retired and needed an updated PSD letter for a housing application. HealifyNow's clinician took the evaluation seriously — not a five-minute rubber stamp. Letter accepted by my new landlord without issue.”
“Combat veteran with PTSD and a trained service dog. Mid-tour I needed new documentation and my VA appointment was 8 weeks out. HealifyNow's evaluation was thorough and the letter helped me secure housing during transition. Grateful.”
“Panic disorder with a partially trained PSD. The clinician was honest — said the letter should specify in-training status. That nuance was exactly what protected me when a landlord later questioned things.”
After your evaluation, your letter is reviewed and signed by one of our letter clinicians.

Straight answers to what people ask us most. Still have a question? Our care team replies within hours.
Contact the care teamNo. A PSD letter documents a psychiatric service dog (trained to perform specific tasks) and is associated with ADA service animal rights. An ESA letter documents an emotional support animal (provides comfort by presence, no task training required) and is associated with Fair Housing Act accommodation only. Different documents, different uses.
No. There is no federal registry of service dogs. Anyone offering 'service dog registration' or 'ADA certification' is selling something with no legal force. What matters is the disability and the dog's training.
Federal rules since 2021 require airlines to accommodate trained service dogs, including psychiatric service dogs, but treat them as service animals (different from previous ESA accommodations, which most airlines have eliminated). Each airline has specific forms (a DOT Service Animal Form) that you submit in advance. HealifyNow can help complete these as needed.
Under the Fair Housing Act, landlords cannot reject a legitimate accommodation request for someone with a qualifying disability and a service animal trained to mitigate it. If your letter is rejected, your clinician can speak with the landlord directly. Persistent issues may be referred to fair housing legal services.
Most landlords accept letters dated within the past 12 months for ongoing accommodation. Renewal is straightforward — typically a follow-up visit to confirm ongoing need.
You need a qualifying mental health condition; you don't necessarily need to be in current treatment. Many members have stable conditions that don't require active treatment but still qualify for a service dog. Your clinician will assess.
A PSD letter is $149 for up to 2 dogs, or $229 for 3 dogs. Booking is free and you only pay if the clinician approves your letter. No hidden fees, no certificate add-ons and no fake registrations.
Many online services offer 'letters' for $50 with no real evaluation. These are increasingly rejected by landlords, courts, and the disability community for harming legitimate service dog handlers. Our letters are issued only after real evaluation by licensed clinicians, and that's what makes them respected.
Book for free, answer a short questionnaire, and meet a licensed mental health professional. If you qualify, your signed PSD letter arrives by email.
You need a mental health condition that substantially limits a major life activity, such as PTSD, panic disorder or major depression, and a dog trained to perform tasks for it.
Examples include deep pressure therapy during panic attacks, interrupting self-harm or repetitive behaviors, waking a handler from nightmares, and grounding during dissociation.
No. Under the ADA, businesses can't require documentation for a service dog. Staff may only ask whether it's a service dog and what task it's trained to perform.
Under the Fair Housing Act, housing providers must reasonably accommodate psychiatric service dogs without pet fees, unless a narrow safety or damage exception applies.
Yes. Airlines treat trained psychiatric service dogs like other service dogs and may ask you to complete the DOT Service Animal Air Transportation Form.
No letter is issued and you aren't charged. If your animal provides comfort but isn't task-trained, an ESA letter may be the right fit.
