Service dog, ESA, or therapy dog — which is it?
Three roles, three very different sets of rights, and mixing them up is where most trouble starts. Answer a question or two for a plain, ADA-accurate answer — and what each can and can't do.
Educational only, not legal advice. This tool does not issue any ID, certificate, or registration — none exists or is required under the ADA.
Is the dog trained to perform a specific task or do work for a person's disability?
A task is a trained action — guiding, alerting to a sound, interrupting a panic attack, retrieving medication, bracing for balance. Comfort just from the dog's presence is not a task.
A task is a trained action — not comfort by presence.
Under the ADA a service dog does work or a task tied to the disability: guiding, alerting to a sound or a blood-sugar change, interrupting a panic attack or a repetitive behavior, deep pressure on cue, retrieving medication, bracing, waking from a nightmare, fetching help. A dog that simply provides comfort by being near you — with no trained action — is not doing a task. With that in mind:
Who does the dog comfort?
A service dog
Because the dog is individually trained to perform a task for a person's disability, it's a service dog under the ADA — with the right to accompany its handler into places open to the public. No registration, certification, ID, or vest is required, and no such credential officially exists. And a psychiatric service dog (trained to interrupt a panic attack, provide deep pressure, and so on) is a full service dog too — the deciding factor is the trained task, not the type of disability.

An emotional support animal (ESA)
The dog helps by its comforting presence rather than a trained task, so under the ADA it's not a service animal and doesn't have public-access rights — it can't go into a "no pets" business the way a service dog can. An ESA does have a real, separate protection: under the Fair Housing Act, for housing. And since the DOT's 2021 rule, airlines treat ESAs as pets, not service animals. The comfort is genuine; it simply lives under a different law.
A therapy dog
A therapy dog visits other people — in hospitals, schools, libraries, or care homes — to offer comfort, usually by invitation and often with a temperament certification from a therapy organization. It does wonderful work, but it has no public-access right of its own under the ADA: it can't go everywhere its handler goes the way a service dog can, because the ADA's access right belongs to the disabled handler of a task-trained service dog.
Frequently asked questions
- What is the difference between a service dog and an emotional support animal?
- A service dog is individually trained to perform a specific task for a person’s disability and has public-access rights under the ADA. An emotional support animal helps by its comforting presence, is not task-trained, and is not a service animal under the ADA — it is protected only for housing, under the Fair Housing Act.
- Is a psychiatric service dog a service dog?
- Yes. A psychiatric service dog trained to perform a task — such as interrupting a panic attack or providing deep pressure on cue — is a full service dog under the ADA. The deciding factor is the trained task, not whether the disability is physical or psychiatric.
- Does any of these need to be registered or certified?
- No. Under the ADA there is no registration, certification, ID card, or vest requirement for a service dog, and no such credential officially exists. Any site selling "registration" is selling a document with no legal weight. This tool is educational and does not issue any ID or certificate.
- What is a therapy dog?
- A therapy dog is a pet whose handler brings it to visit others — in hospitals, schools, or libraries — to provide comfort, by invitation. It has no public-access right of its own under the ADA.
