Service Dog vs. Emotional Support Animal: What Is the Difference?

Understand the task-training distinction and why service dogs and emotional support animals have different public-access rules.

The defining difference is trained work or tasks

Under the ADA, a service dog is individually trained to perform work or tasks directly related to a person’s disability. An animal whose presence provides comfort without trained disability-related work is not a service animal under the ADA.

Psychiatric service dogs can still be service dogs

A psychiatric disability does not make a dog an emotional support animal. If the dog is trained to take a specific action—for example, interrupting or responding to a disability-related episode—it can meet the service-animal definition.

Housing is different

HUD uses the broader term assistance animal in housing. An assistance animal can include an animal that provides disability-related emotional support, which is why housing rights should not be analyzed using public-access ADA rules alone.
