How to use these guides
A psychiatric service dog (PSD) is a dog trained to perform specific tasks that help a person manage a mental health disability. Because the rules change depending on where you are, these guides are organized around real situations: your home, a flight, a store, your job, your child's school.
Each guide explains what the law says, what people commonly misunderstand, and what you can do next. We link to the government and professional sources behind each point so you can check them yourself. Rules can change, so it's worth confirming details with the agency or provider involved before you rely on them.
Psychiatric service dog basics
If you're new to this, begin with what a psychiatric service dog is and how it differs from other assistance animals. The key idea is training: under the Americans with Disabilities Act (ADA), a dog qualifies because it has been individually trained to do work or perform tasks related to your disability, not because its presence is comforting.
From there, our comparison guides explain how a PSD relates to other service dogs and to emotional support animals, and our training guides walk through humane, reward-based ways to build the skills a working dog needs.
- What a psychiatric service dog is, and what it isn't
- How a PSD compares with other service dogs
- How PSDs are trained, and why humane methods matter
- What to look for in a dog's temperament, whatever the breed
- A public access training checklist you can work through
Housing, travel and work guides
Different laws apply in different places. In housing, the Fair Housing Act requires reasonable accommodations, and a landlord may ask for reliable documentation when your disability-related need isn't obvious. For flights, the Department of Transportation's rules let airlines require a standard DOT form. At work, requests go through the ADA's reasonable accommodation process.
Our guides on landlords, flying, letter validity and the workplace explain what each party can ask for and how to prepare. A PSD letter from a licensed clinician can support a housing request, but it is never a guarantee of any outcome.
Public access guides
In restaurants, stores and most other businesses open to the public, the ADA governs. Staff may ask only two questions when it isn't obvious that your dog is a service animal, and they can't require documentation, an ID card, a vest or a demonstration. A PSD letter isn't needed for public access and doesn't grant it.
Our guides on vests, registries and public places cover what staff can and can't do, when a dog can be asked to leave, and why online registries and certificates carry no legal weight.
PSD letter guides
If you have a psychiatric disability and a dog that is task-trained or in training, you may want a letter from a licensed clinician for housing or travel planning. Our step-by-step guide explains what an evaluation involves, what a legitimate letter includes, and the red flags to avoid.
With usaPsdletter.com, booking the evaluation is free and you pay only if the clinician finds a letter appropriate. If your dog provides comfort but isn't task-trained, an emotional support animal letter may be the more accurate document, which we explain in our comparison guides.
Mental health crisis support
A service dog can be a meaningful part of managing a mental health condition, but it doesn't replace treatment. If you're in crisis or thinking about harming yourself, call or text 988 to reach the 988 Suicide & Crisis Lifeline, or call 911 in an emergency.
