These two get treated as synonyms constantly, and they are closer to opposites. A therapy dog goes to a hospital to comfort strangers and returns home as an ordinary pet. An emotional support animal stays home and helps exactly one person. Different jobs, different rules, different paperwork.
Of the three terms, therapy dog is the most misused. A therapy dog visits hospitals and schools to comfort strangers, then goes home an ordinary pet, which is close to the opposite of an emotional support animal.

The full picture
| Therapy dog | Emotional support animal | Service dog | |
|---|---|---|---|
| Who it helps | Other people, in facilities | Its owner, at home | Its handler, anywhere |
| Trained tasks | No - temperament, not tasks | None required | Yes, and this defines it |
| Public access | By invitation only | None | Yes, under the ADA |
| Housing accommodation | Not on that basis | Yes | Yes |
| Assessed by | A volunteer organisation | A licensed clinician, assessing the owner | Its own demonstrated work |
| Meaningful credential | Organisation registration and insurance | The clinician's letter | The trained work itself |

A test that works
If you can only remember one thing from this page, make it a question about direction. Everything else follows from the answer, including which paperwork matters and which rights exist.
It works because these three categories are not points on a scale of seriousness. They are different jobs, and the job determines the rules.
Who is the dog working for - you, or somebody else?
The distinction the whole field turns on
Working for other people, on a visiting basis, in institutions: that is therapy work, and it is genuinely valuable and genuinely assessed. It carries no rights that follow the dog home.
Working for you, by being present: an emotional support animal, established through an assessment of you rather than of the dog, with housing accommodation and nothing beyond it.
Working for you, by performing trained actions: a service dog, where the work creates the access, and where no document substitutes for the training.
Ten answers
What is a therapy dog?
A dog that visits places - hospitals, care homes, schools, courts - to provide comfort to the people there. It works for others, alongside its handler, and it is usually assessed and insured by a volunteer organisation.
Is a therapy dog the same as an emotional support animal?
They are close to opposites. A therapy dog helps strangers in institutions and goes home afterwards as an ordinary pet. An emotional support animal helps one person, its owner, and does nothing for anybody else.
Does a therapy dog have public access rights?
No. It enters buildings by invitation, because the hospital or school has a visiting programme and has agreed to it. Remove the invitation and the dog has no more right of entry than any other pet.
Is therapy dog certification real?
Unlike ESA certification, yes - in a limited sense. Volunteer organisations assess temperament and behaviour, then register and insure their teams. That registration is meaningful to the facilities they visit and means nothing outside that context.
Can my therapy dog live with me in no-pets housing?
Not on the strength of its therapy work, because that work benefits other people rather than you. Should you independently need an assistance animal in your own home, that is a separate application judged on its own facts.
Which is hardest to obtain?
Therapy work has the clearest published standard, because organisations set entry tests and most dogs fail them on temperament. Service dog training is far longer. An emotional support animal involves an assessment of the person rather than the animal.
Can one dog do more than one of these roles?
Rarely well. A therapy dog visiting a ward is doing a job that requires it to be interested in strangers. A service dog is trained to ignore them. The temperaments pull in different directions.
Do therapy dogs help with my own anxiety?
In a session, plainly yes for many people. But the dog is not yours and the arrangement is a visiting programme, so it addresses nothing about your housing or your daily life at home.
Why do people confuse the terms?
Because all three involve dogs and wellbeing, and because sellers of certificates use the words interchangeably to widen their market. Facilities and landlords do not confuse them, which is where the mismatch bites.
Can I take a therapy dog into a shop?
No. Only trained service animals have that right. A therapy dog in a supermarket is a pet in a supermarket, whatever its organisation's identification card says.
Then what you are describing is an assistance animal, and the route runs through an assessment rather than an organisation. Find out at no cost whether one fits.
