Under the Americans with Disabilities Act, a service dog does have to be on a leash, harness, or tether in most public settings, but there are two exceptions: the dog can work off-leash if the tether would interfere with its trained tasks, or if the handler’s disability makes using one impossible. Even then, the handler has to keep the dog under control through voice commands, hand signals, or another effective method. Air travel is stricter and does not allow the off-leash option at all.
The Federal Leash Rule
Two parallel ADA regulations set the standard. Title II covers state and local government facilities under 28 C.F.R. § 35.136, and Title III covers private businesses like restaurants, hotels, and stores under 28 C.F.R. § 36.302. Both say the same thing: a service animal must have a harness, leash, or other tether unless one of the two exceptions applies.1eCFR. 28 CFR 36.302 – Modifications in Policies, Practices, or Procedures The rule works the same way whether you are at city hall or a coffee shop.
The ADA defines a service animal as a dog individually trained to do work or perform tasks related to a person’s disability.2eCFR. 28 CFR 36.104 – Definitions Miniature horses fall under a separate, narrower provision, but the leash and control rules still apply to them.
The Two Off-Leash Exceptions
The regulations name two specific situations in which a service dog can work without a physical tether.
The first is when a leash, harness, or tether would interfere with the dog’s ability to safely and effectively do its trained work.3eCFR. 28 CFR 35.136 – Service Animals A guide dog moving through a crowd may need range that a short leash denies it. A psychiatric service dog trained to create physical space between the handler and other people cannot do that job tethered to the handler’s side. A dog trained to retrieve dropped items or medication may need to move several feet away to complete the task.
The second exception is for handlers whose disability prevents them from holding a leash. Someone who uses both hands to operate a wheelchair, or a person with limited grip strength or dexterity, may not be able to hold one securely.1eCFR. 28 CFR 36.302 – Modifications in Policies, Practices, or Procedures The law does not force a handler to choose between their mobility device and their service animal’s help.
Retractable Leashes
Some handlers use a retractable leash to give the dog working room while keeping a physical connection. The Department of Justice’s own guidance uses the example of a wheelchair user who deploys a long retractable leash so her service dog can retrieve items at a distance. The dog still cannot wander freely, and the handler still has to keep it under control at all times.4U.S. Department of Justice. Frequently Asked Questions About Service Animals and the ADA A retractable leash satisfies the tether requirement without loosening the control standard.
Control Without a Leash
Dropping the leash does not drop the obligation to control the dog. When a service dog works off-leash under either exception, the handler must maintain control through voice commands, hand signals, or other effective means.3eCFR. 28 CFR 35.136 – Service Animals In practice, the dog should stay close, ignore strangers and other animals, avoid unnecessary barking, and respond promptly when directed.
This is where training quality shows. An off-leash service dog that drifts across a restaurant, sniffs at diners, or ignores its handler’s recall is not meeting the control standard, no matter how it was trained on paper. The regulation does not spell out a specific distance or reaction time. The test is functional: can the handler reliably direct the dog’s behavior without a physical connection? If the answer is no, the off-leash exception does not apply.
Air Travel: No Off-Leash Option
Flights follow the Air Carrier Access Act, not the ADA, and the leash rule is tighter. Under 14 C.F.R. § 382.73, airlines can require a service animal to be harnessed, leashed, or tethered at all times in the airport and on the aircraft.5eCFR. 14 CFR 382.73 – How Do Carriers Determine if an Animal Is a Service Animal There is no voice-control exception.
The Department of Transportation concluded that non-physical means of control could create safety problems in the confined cabin of an aircraft.6Federal Register. Traveling by Air With Service Animals The DOT’s service animal transportation form requires handlers to attest that the animal will be harnessed, leashed, or tethered at all times in the airport and on the aircraft.7U.S. Department of Transportation. Service Animal Air Transportation Form If a handler’s disability prevents them from keeping physical control, the airline may deny transport of the animal in the cabin, even where the ADA would allow voice-control on the ground. Handlers who normally work their dogs off-leash need to plan around this when flying.
Leashing in Housing
In rental housing, condominiums, and other residential settings, the Fair Housing Act governs. It uses the broader term “assistance animal,” which covers trained service dogs and emotional support animals, and requires housing providers to make reasonable accommodations even if the property has a no-pets policy.
The FHA does not carry the same detailed leash language as the ADA, but the handler is still responsible for controlling the animal. A housing provider can deny an accommodation request if the specific animal poses a direct threat to others that cannot be reduced through the handler’s actions, such as securing the animal.8U.S. Department of Housing and Urban Development. HUD FHEO Assistance Animals Notice 2020 In shared areas like hallways, lobbies, and courtyards, the building’s general pet-leash policy can typically apply to assistance animals, as long as it does not effectively block a person with a disability from using the animal. A housing provider can require leashing in common spaces as a reasonable safety measure, but cannot use a leash rule as a pretext to bar the animal.
State and Local Leash Laws
The ADA sets a floor. State and local governments cannot pass laws that reduce these rights.9U.S. Department of Justice. Americans with Disabilities Act of 1990, As Amended A city ordinance requiring all dogs to be leashed in public does not override the ADA’s off-leash exceptions for service animals. If a handler qualifies for one of those exceptions, a local leash law cannot force them to use one.
States can go further than federal law, though. Some extend public access rights to animals beyond dogs, broaden the definition of disability, or impose penalties on businesses that wrongfully deny entry. A growing number of states also make it a misdemeanor to fraudulently misrepresent a pet as a service animal.
Emotional Support Animals Are Not Covered
The off-leash exceptions above apply only to trained service dogs. Under the ADA, emotional support, therapy, comfort, and companion animals are not service animals because they have not been trained to perform a specific task related to a disability.4U.S. Department of Justice. Frequently Asked Questions About Service Animals and the ADA An emotional support animal has no federal right to enter a restaurant, store, or government building at all, let alone to be there without a leash. Emotional support animals do have some protections under the Fair Housing Act for residential settings, but those rights are separate from, and narrower than, ADA service animal rights. Airlines also no longer recognize emotional support animals under the ACAA, classifying them as pets since the 2021 rule change.
A psychiatric service dog is different. If a dog is trained to detect the onset of a panic attack and perform a specific intervention like deep pressure therapy or leading the handler to a safe space, that is task-trained work and the ADA’s leash rules, including the off-leash exceptions, apply the same way they do to any other service dog.
