There are many laws and regulations (both state and federal) that apply to pets and their owners. These laws are designed to keep both animals and people safe and to ensure the general well-being of the public. But many of the laws that apply to a pet are waived or altered in some way to accommodate service animals. If you've been wondering how leash laws and other pet-related laws apply to your emotional support animal, here's what you should know.
Defining a Service Dog
We know that your ESA dog is an important part of your treatment, and essential to coping with your condition. However, in most circumstances, an ESA does not qualify as a service animal. This means that any pet-related laws in your area do apply to your ESA, and there are very few situations under which your dog will be treated as a service animal.
A service dog is defined as a dog that is trained to perform a specific task in order to assist someone with a disability. Because most ESAs are not given task-specific training, and their handlers simply need their presence for comfort, they are not considered service animals. So, please be aware that the majority of public places (restaurants, stores, etc.) that do not allow pets have the discretion to allow an ESA. However, there are exceptions, so if you want to bring your ESA somewhere public with you, do some research, or call the location and ask if they'll allow a support animal on the premises.
Leash Laws
It's important to note that, while other regulations may be waived for service animals, leash laws are not altered for dogs that provide a service or support to their handler. Whatever a dog's job may be, they are subject to the local dog licensing and registration requirements and must be on a leash unless they are in an area where leashes are not required.
In fact, laws strictly state that service animals must be under control at all times. This means they should be leashed, tethered, or otherwise harnessed in public areas. The only exception to this is if the leash directly interferes with a dog's duties. When this occurs, the dog may be taken off the leash to perform the necessary task but must be kept under control by voice commands.
What Laws Protect Your ESA?
Though the majority of laws that protect service animals do not apply to emotional support animals, there are a few exceptions. If you have an ESA, then you're provided with two primary benefits:
- Housing. Under the Fair Housing Act, you can keep your ESA in housing even where pets aren't allowed, and a landlord generally cannot charge a pet fee — provided you have a valid ESA letter from a clinician licensed in your state.
- Air travel has changed. Since the Department of Transportation's 2021 rule, U.S. airlines no longer treat ESAs as service animals. An ESA now flies as a pet, subject to the airline's pet-in-cabin fee and size limits — it is not entitled to free cabin access. Only a trained service dog, including a psychiatric service dog, flies in the cabin at no charge (on the DOT form). See our guide on flying with an emotional support animal for the details.
While the law doesn't require ESAs, or even service dogs, to be marked as such, many handlers find it helpful to have their dog wear a vest when out in public. A vest signals that the dog is a working or support animal and can reduce friction in pet-friendly settings — but be clear with yourself about what it does and doesn't do: a vest is identification, not an access pass, and it won't give an ESA entry to a plane cabin or a store that an ESA isn't otherwise entitled to.

Frequently Asked Questions
Do service dogs have to be on a leash?
Yes, in most cases. Under the ADA, a service dog must be on a leash, harness, or tether, unless those devices interfere with the dog's task or the handler's disability prevents their use - in which case the handler must keep the dog under control through voice or signal commands.
Can a service dog be off-leash?
A service dog may work off-leash only when a leash would interfere with its trained task or the handler's disability makes a leash impractical. Even then, the dog must remain under the handler's control at all times.
Can a business remove a service dog that is not under control?
Yes. Under the ADA, a business may ask a handler to remove a service dog that is out of control and not brought back under control, or that is not housebroken. The business must still offer its goods or services without the dog present.

A therapist-signed PSD letter documents your service dog
Psychiatric handlers can get a therapist-signed PSD letter — the documentation of a task-trained service dog's clinical basis that landlords and airlines ask for. Here's how the psychiatric service dog letter works.
