What a service dog is
A service dog is a dog trained to perform specific special tasks related to the individual functional needs of its handler. The key feature is not the dog's character but the presence of a trained functional action.
- A service dog is trained to perform specific tasks, not just to be near a person.
- The tasks are tied to the individual needs of a specific handler and are not a universal set.
- Good behavior and obedience alone do not make a dog a service dog — what matters is a trained special task.
- Service dog status is not determined by a vest, a tag or any single document.
What an ESA is
An emotional support animal (ESA) is an animal whose presence helps a person emotionally. This status is described differently from that of a service dog and requires careful wording.
- An animal's emotional support can be an important and meaningful part of a person's life.
- An ESA is usually not defined by performing trained special tasks — the key role is played by the animal's presence, not a trained action.
- Access and transport rules for an ESA depend on the applicable requirements of the specific country, organization or carrier.
- It cannot be claimed that an ESA has the same rights as a service dog — the scope of permitted rights differs and must be checked separately in each case.
What a therapy dog is
A therapy dog performs a different function from the service dog of a specific handler.
- A therapy dog may work with different people rather than with one permanent handler.
- Such work usually takes place in institutions (for example hospitals, schools, care homes) or within organized programs.
- A therapy dog is not necessarily the individual service dog of a specific handler and does not replace that function.
Pet
Training and a calm temperament do not by themselves change a dog's status.
- A trained, calm pet remains a pet if it does not perform functional tasks within a training program.
- Obedience or a certificate for a general training course is not equivalent to service dog status.
Comparison by key features
The table summarizes the differences. It does not replace checking the specific requirements of a jurisdiction, organization or carrier.

|---|---|---|---|---|---|
| Service dog | A person with functional limitations | Yes, trained | Yes | Governed by applicable requirements | Required in every jurisdiction |
| Emotional support animal (ESA) | A person who needs emotional support | Usually no | Usually yes | Limited, depends on requirements | Required in every jurisdiction |
| Therapy dog | Different people within a program | Not in this sense | Not tied to one handler | Usually does not include general access | Required at the host institution |
