The difference
PSD vs. ESA — what sets them apart
A Psychiatric Service Dog (PSD) is individually trained to perform specific tasks that help mitigate the effects of a psychiatric disability. These tasks may include interrupting panic attacks, providing deep pressure therapy, reminding you to take medication, guiding you during dissociation, or creating space in crowded environments. Because a psychiatric service dog performs trained disability-related tasks, it is recognized as a service animal under the Americans with Disabilities Act (ADA) and may accompany its handler in most public places.
A PSD letter is issued by a licensed mental health professional after a legitimate clinical evaluation. The letter documents your disability-related need for a task-trained service dog and may support housing accommodation requests, workplace accommodations, and other situations where professional documentation is requested. While airlines primarily rely on the DOT Service Animal Air Transportation Form, a psychiatric service dog letter remains valuable supporting documentation.

What a PSD letter is not
A PSD letter is not a certification, registration, ID card, or training certificate. No document alone makes a dog a psychiatric service dog. Your dog becomes a service animal through individual task training, while the letter documents your disability-related need. We never sell registrations or guarantee approval—our clinicians make independent clinical decisions based on your evaluation.
Training paths
The ADA allows you to owner-train a psychiatric service dog or work with a professional trainer. During your evaluation, your clinician can discuss whether a PSD letter is appropriate for your situation, but training remains the handler's responsibility.
