New Hampshire follows the ADA definition (dogs only) and lets defined service animal trainers bring dogs in training into public facilities. Putting a service animal vest, collar, leash, sign or harness on an animal that is not a service animal is a misdemeanor. The state also offers a voluntary "G C D-Permanent Registration" tag, and the statute itself says that tag "shall not be used to verify the legitimacy or authenticity of a service animal for any purpose".
Who counts as a service animal in New Hampshire?
"'Service animal' means any dog individually trained to do work or perform tasks for the benefit of an individual with a disability, including a physical, sensory, psychiatric, intellectual, or other mental disability. Other species of animals, whether wild or domestic, trained or untrained, are not service animals for purposes of this definition" (RSA 167-D:1, IV). And "the provision of emotional support, well-being, comfort, or companionship does not constitute work or tasks" (167-D:2, II). This tracks the ADA, dogs only.
The federal rule in full is in ADA service dog laws.
Public places in New Hampshire, including hotels and restaurants
"It is lawful for any service animal to accompany his or her handler or trainer into any public facility, housing accommodation, or place of public accommodation to which the general public is invited, subject only to the conditions and limitations established by law and applicable alike to all persons" (RSA 167-D:4). Interfering with a handler or trainer is a misdemeanor (167-D:8, I and 167-D:10). The state law does not list staff questions.
The ADA applies in New Hampshire too. Staff may ask only whether the dog is required because of a disability and what task it is trained to perform. They may not ask for documents or a demonstration, and may remove a dog only if it is out of control or not housebroken. See what businesses can ask.
Service dogs in training in New Hampshire
Yes, for defined trainers. "A service animal trainer, while engaged in the actual training process and activities of such animals, shall have the same rights and privileges with respect to access to public facilities" as handlers (RSA 167-D:6). A trainer is a person employed to train dogs for, or volunteering to raise dogs for, a provider of service animals; an individual trainer who helps a person with a disability train their own service animal; or a trainer who tests animals for the state tag (167-D:1, V). A person training alone, with none of those connections, is not clearly covered. No ID is required.
This is state law only. Under the ADA, "the dog must already be trained before it can be taken into public places," and airlines do not treat dogs in training as service animals. Compare states in service dogs in training.
Is there a New Hampshire service dog registration or tag?
Yes, and it is voluntary. "Certificates and tags stamped 'G C D-Permanent Registration' with a registration number shall be issued by the governor's commission on disability to those who wish to affix such a tag on their service animal's collar," after the dog is registered with the town (RSA 466:8, V). The same paragraph adds: "Tags issued by the governor's commission on disability shall not be used to verify the legitimacy or authenticity of a service animal for any purpose." So a business cannot demand it, and the ADA bars document demands anyway. Asking for the tag for an animal that is not a service animal is itself unlawful (167-D:8, II).
For licensing, "No fee shall be required for the registration and licensing of a service animal dog" (466:8, II). The owner shows an ID card from a recognized training agency; an owner-trained dog must meet the International Association of Assistance Dog Partners' minimum public access standards as determined by a service animal trainer, plus a letter from a health care professional.
A private registry card, ours included, is not a state tag. The Department of Justice says such documents "do not convey any rights under the ADA." Our voluntary registry is a paid, optional record (an emergency contact, a card with the two ADA questions) and nothing more.
Housing: service dogs and ESAs in New Hampshire
Service dogs may accompany their handler into any "housing accommodation" (RSA 167-D:4). We found no New Hampshire statute specific to emotional support animals, and no ESA fraud penalty. ESA requests are reasonable accommodations under the state Law Against Discrimination (RSA 354-A) and the federal Fair Housing Act.
Federal enforcement narrowed in 2026. A May 22, 2026 HUD memo says its fair housing office "will find reasonable cause and recommend charges only for those cases involving animals trained to provide disability-related assistance." The Fair Housing Act and private lawsuits remain, but for an untrained ESA, New Hampshire law now matters more.
ESA letters in New Hampshire
We found no New Hampshire statute on who may write an ESA letter. The federal baseline is the 2004 HUD and DOJ Joint Statement, which is still posted: a housing provider may ask for reliable information showing the disability and the need for the animal, and "In most cases, an individual's medical records or detailed information about the nature of a person's disability is not necessary for this inquiry."
We never sell or refer ESA letters. Ask the clinician who already treats you, and see ESA letters for housing for what a legitimate letter covers.
Employment: service dogs at work in New Hampshire
Public access rules do not govern the workplace. At work, a service dog is a reasonable accommodation request under Title I of the ADA, and unlike a store, an employer may ask for "reasonable documentation about his/her disability and functional limitations" when the need is not obvious (EEOC guidance). The Job Accommodation Network says employers "must consider the request, but do not have to automatically allow employees to bring their service animals to work."

Misrepresentation penalties in New Hampshire
"It is unlawful for any person to fit an animal with a collar, leash, vest, sign, or harness of the type which represents that the animal is a service animal, or service animal tag issued under RSA 466:8 or to request a service animal tag issued under RSA 466:8 if in fact said animal is not a service animal" (RSA 167-D:8, II). It is also unlawful "to impersonate, by word or action, a person with a disability for the purpose of receiving service dog accommodations or service animal accessories" (167-D:8, IV). A violation is a misdemeanor (167-D:10, I). Unless the state gives notice of a class A charge, it is presumed class B, with a fine of up to $1,200; class A carries up to $2,000 and a year in jail.
At least 36 states penalize misrepresentation in some form; see fake service dog laws by state.
Where to file a complaint in New Hampshire
Interfering with a service animal handler or trainer is a misdemeanor in New Hampshire, and housing discrimination falls under RSA 354-A. Federal routes are open too:
- Public places: the U.S. Department of Justice, through ADA.gov's complaint page.
- Housing: HUD's complaint page, though HUD now finds cause in animal cases only for trained animals.
- Work: the EEOC, through its page on filing a charge.
Rules change at the state line. Nearby: Maine service dog laws and Vermont service dog laws.
Common questions
Does New Hampshire have a service dog registry?
It has a voluntary state tag from the Governor's Commission on Disability. By law the tag cannot be used to verify that an animal is a service animal.
Can a store ask to see the New Hampshire tag?
No. The statute says the tag is not for verification, and the ADA bars businesses from requiring documentation.
Is it illegal to put a service dog vest on my pet in New Hampshire?
Yes. It is a misdemeanor under RSA 167-D:8, II.
Do emotional support animals have public access in New Hampshire?
No. The state definition is dogs trained for tasks, and emotional support is not a task.
