Maryland Dog Registration Information

If you’re asking where do I register my dog in Maryland for my service dog or emotional support dog, the key point is this: Maryland does not have a single statewide “service dog registration” or “ESA registration” office for the public. What most people actually need is a dog license in Maryland (sometimes called an animal control dog license Maryland residents obtain through local government), which is typically issued by your county or city animal services/licensing office.

This page explains where to register a dog in Maryland for licensing purposes, how local licensing works, what you’ll need (including rabies vaccination proof), and how licensing differs from a dog’s service dog legal status or an emotional support animal (ESA) housing accommodation.

Where to Register or License Your Dog in Maryland

Because dog licensing in Maryland is usually handled locally, start with the animal services, animal control, or licensing office for the county (or city) where you live. The offices below are examples of official local government locations that publish licensing information and handle licensing, animal control, and/or rabies enforcement.

If your county isn’t listed above, search your local government site for terms like “animal services,” “animal control,” “dog licensing,” or “rabies & licensing.” In Maryland, those local offices are typically the primary agencies responsible for licensing compliance and many rabies-related enforcement steps (such as bite reporting coordination).

Overview of Dog Licensing in Maryland

Who issues a dog license in Maryland?

In practice, a dog license in Maryland is usually issued by the county (or a city with its own program) where the dog lives. That’s why the most accurate answer to where to register a dog in Maryland is: your local animal services / animal control / licensing office. These local programs are the ones that typically sell tags, process renewals, and set local deadlines, fees, and enforcement steps.

What licensing is (and is not)

A license is typically a local registration/tag tied to basic public-health and animal-control requirements—most importantly, proof of current rabies vaccination. A license is not a disability accommodation record, and it is not a legal certification that a dog is a service animal.

Why counties care about licensing

Local licensing helps counties:

• confirm rabies vaccination compliance and support rabies control efforts,
• return lost dogs to owners faster,
• fund animal services operations, and
• enforce local animal control ordinances (leash laws, nuisance rules, and more).

How Dog Licensing Works Locally in Maryland

Step 1: Confirm your local rules (county/city)

Start with your county or city animal services website or office. Requirements can differ by jurisdiction, including: the age when a dog must be licensed, how soon after moving you must obtain a license, license term options, and whether discounts apply for altered dogs or seniors. For example, Baltimore County describes annual licensing for dogs and cats four months and older kept in the county for longer than 30 days per year, and it notes that service dog licenses may require special handling (not completed online).

Step 2: Get (and keep) rabies vaccination current

Maryland regulations require owners/custodians to have dogs, cats, and ferrets vaccinated against rabies by 4 months old and to obtain proper rabies vaccination documentation (a certificate) completed by a Maryland-licensed veterinarian (or authorized clinic process). Local licensing offices commonly require you to submit a copy of that rabies certificate to issue or renew a license tag.

Step 3: Apply online, by mail, or in person (varies)

Many counties offer online licensing, but some licenses (including some service-dog related license options) may require mail or in-person processing depending on the jurisdiction. Prince George’s County, for instance, lists a walk-in/mail-in licensing section and additional walk-in only locations within the county for purchasing licenses. Anne Arundel County publishes options that include purchasing licenses online and also provides administrative hours for licensing-related services.

Step 4: Keep your tag and records accessible

After approval, your local office typically issues a license tag. Keep your rabies certificate and licensing receipt in a safe place. If animal control needs to confirm licensing or rabies status (for example, after a bite incident), having documentation available can speed up the process.

What if my dog is a service dog or ESA—do I still license?

In many places, yes: your dog may still need a local license even if it is a service dog or an emotional support animal. Some counties may offer fee exemptions or special categories for service animals, but the dog may still need to meet core public-health requirements (including rabies vaccination) and local licensing rules. Ask your local office directly whether your jurisdiction offers an exemption, discount, or a specific “service animal” license type and what proof (if any) they require for that local licensing category.

Service Dog Laws in Maryland

What makes a dog a service dog (public access)

Under the Americans with Disabilities Act (ADA), a service animal is a dog that is individually trained to do work or perform tasks for a person with a disability. The task(s) must be directly related to the person’s disability. The ADA also explains that service animals are not required to be certified, professionally trained, or registered, and they do not have to wear a vest or special ID.

There is no official “ADA registration” you must buy

If you see ads promising “official service dog registration,” “national registry,” or paid certification for public access, be careful. For ADA public-access rights, the key is training and task work, not paperwork. Businesses and state/local government facilities generally may ask only two questions when it is not obvious a dog is a service animal: (1) whether the dog is a service animal required because of a disability, and (2) what work or task the dog has been trained to perform. They are not allowed to require documentation that the dog is registered, licensed, or certified as a service animal.

How this connects to licensing in Maryland

Even when a dog is a legitimate service dog under the ADA, local licensing is a separate process. A local animal control dog license Maryland residents obtain is about public health and local ordinance compliance (often including rabies). Service dog status is about disability access rights and task training.

Emotional Support Animal Rules in Maryland

ESAs are different from service dogs

An emotional support animal (ESA) generally provides comfort by being with a person. Under the ADA, that kind of comfort alone is not considered a trained task, so ESAs do not receive the same public-access rights as service dogs under the ADA. That’s why “registering” an ESA for public access is usually a misunderstanding of how the law works.

Where ESAs matter most: housing (and sometimes other limited contexts)

ESAs are most commonly handled in the context of housing accommodations (for example, a request to keep an animal in housing with a no-pets policy). Those housing rules are different from ADA public-access rules. If you’re trying to comply with Maryland dog licensing at the same time, treat these as two parallel tracks: (1) your local dog license/rabies compliance, and (2) a separate housing accommodation request process if applicable.

What to avoid

Avoid paying for third-party “ESA registrations” or “service dog certifications” that claim to create legal status. Local government licensing offices generally do not require those paid registries for licensing, and ADA public-access service dog status does not depend on buying a registration.
