Maryland does not set a statewide limit on how many dogs you can have. The cap is local: most counties allow three or four dogs per household without a permit, one major county sets no numerical maximum at all, and going above the default number generally requires a kennel or hobby license tied to how your property is zoned. Your landlord or HOA can also set a lower limit than your county does.
County Limits Without a Permit
Because animal control is delegated to local governments, the answer changes with your address. The limits in several of Maryland’s most populated jurisdictions:
- Baltimore County: three dogs. More than three requires a holding facility or kennel license, and the property must be zoned to allow it.1Baltimore County Government. Miscellaneous Permits and Licenses
- Prince George’s County: up to four domestic animals per household. Five to ten animals four months or older and larger than a guinea pig requires a hobby permit.2Prince George’s County. Animal Management Division
- Anne Arundel County: four dogs. Five or more dogs four months or older requires a dog fancier license, which carries lot-size minimums.3Anne Arundel County Government. Dog Fancier License
- Montgomery County: no code limit on the number of pets in a home. Owners still have to meet sanitation, noise, and space requirements, and keeping animals in inadequate conditions can bring fines of $500 to $1,000 and up to 90 days in jail.4Montgomery County.

A few points catch people off guard. Prince George’s counts all domestic animals toward its four-animal cap, not just dogs, so two cats and two dogs already puts you at the ceiling. Montgomery has no hard number, but “no limit” is not “no rules”: if the number or size of your animals creates unsanitary or unsafe conditions, you are in violation regardless of the count. Counties not listed here have their own rules, and smaller municipalities sometimes add restrictions on top of county law. Call your local animal control office before adding a dog that could push you over.
Kennel and Hobby Permits
If you want more dogs than the default, the path is a kennel license or hobby permit. Names and thresholds vary. Baltimore County requires a kennel or holding facility license for anyone with more than three dogs, and the property must be zoned appropriately.1Baltimore County Government. Miscellaneous Permits and Licenses Prince George’s uses a hobby permit for five to ten animals.2Prince George’s County. Animal Management Division Anne Arundel’s dog fancier license is tied directly to lot size.3Anne Arundel County Government. Dog Fancier License
Expect to submit vaccination records, a description of your facilities, and the number and ages of the dogs you plan to keep. Most counties inspect before issuing and revisit periodically after. Failing sanitation, space, or humane care standards can bring fines or revocation.
Separate from the county caps, Maryland law imposes a statewide kennel license requirement on anyone who owns or has custody of six or more unspayed female dogs over six months old kept for breeding, or who sells dogs from six or more litters in a year. That license comes from the local licensing agency and applies regardless of your county’s general pet limits.6Maryland General Assembly. Maryland Local Government Code 13-108 – Kennel License Fees vary. In Montgomery County, a commercial kennel license runs $75 for 25 or fewer animals and $125 for 26 or more.
Zoning and Lot Size
Zoning often decides whether you can even apply for a permit. Residential zones tend to be tighter, and in many counties you simply cannot get a kennel license on a residential lot, no matter how much land you have.
Anne Arundel spells out the math. Five or six dogs requires a lot of at least 25,000 square feet, roughly 0.57 acres. Seven dogs requires at least 40,000 square feet, about 0.92 acres. Each dog beyond seven adds another 5,000 square feet.3Anne Arundel County Government. Dog Fancier License These sit in the zoning ordinance, so a polite request will not move them.
Baltimore County ties licensing to zoning without publishing that kind of acreage table: the property must be zoned for a holding facility or kennel before the county will license more than three dogs.1Baltimore County Government. Miscellaneous Permits and Licenses A standard suburban lot usually will not qualify. Before you buy or adopt a dog that would push you over the limit, call your county’s zoning office to confirm the property can support the permit.
Landlord and HOA Limits
Even if the county would allow more dogs, your landlord or homeowners association can impose a stricter cap. These private agreements are enforceable.
Maryland landlords can restrict the number, size, breed, or type of pets through a lease or pet addendum. A signed addendum is a binding contract, and violating it can bring fees, forced pet removal, or eviction. Pet deposits typically run $150 to $500, and many leases include specific language on liability for animal damage.
HOAs in planned communities frequently cap dogs at one or two per household or ban certain breeds outright. The restrictions live in the community’s covenants and are enforced through fines. If you are buying into an HOA community, read the pet rules in the declaration of covenants before you close. Changing them later usually takes a vote of the membership.
Assistance Animals
Federal disability law creates one meaningful exception, and it matters more for housing than for local pet caps.
Service Dogs Under the ADA
The Americans with Disabilities Act requires public entities and businesses to allow service dogs individually trained to perform tasks for a person with a disability. The ADA does not broadly exempt service dogs from local pet ownership limits, and they remain subject to local licensing and vaccination rules like any other dog.7ADA.gov. Frequently Asked Questions About Service Animals and the ADA The ADA’s reach is public access, not your county’s dog count.
Assistance Animals Under the Fair Housing Act
The Fair Housing Act is where the housing exception lives. Landlords, HOAs, and other housing providers must make reasonable accommodations for assistance animals, which include trained service dogs and emotional support animals. A “no pets” policy or a numerical pet limit has to give way when a person with a disability needs an assistance animal, and landlords cannot charge pet deposits or fees for one.8U.S. Department of Housing and Urban Development. Assistance Animals
If your disability or the need for the animal is not obvious, the housing provider can ask for documentation from a healthcare professional confirming a disability-related need. They cannot demand your medical records. Maryland’s own anti-discrimination law reinforces these protections at State Government Article ยง 20-706. A provider can deny the request only in narrow circumstances: if the specific animal poses a direct threat to safety, would cause significant property damage, or if the accommodation would impose an undue burden.8U.S. Department of Housing and Urban Development. Assistance Animals A blanket refusal based on breed, size, or number is not enough on its own.
Penalties for Going Over the Limit
Consequences run from civil fines to criminal charges depending on how bad the conditions are.
Keeping more dogs than your county allows without a permit usually starts as a civil citation. Many counties give you a window to either rehome the extra animals or apply for the right license. Fines escalate with repeat violations.
When animal welfare enters the picture, the exposure gets much worse. Maryland’s criminal animal cruelty statute makes it a misdemeanor to fail to provide adequate food, water, space, shelter, or veterinary care, carrying up to 90 days in jail and a fine of up to $1,000. A court can order the defendant to pay the costs of removing, housing, treating, or euthanizing confiscated animals, and can prohibit the person from owning or possessing animals as a condition of probation.9Maryland General Assembly. Maryland Criminal Law Code 10-604 – Abuse or Neglect of Animal That last piece is the one people underestimate: a conviction can mean losing all of your animals, not just the ones over the limit.
Montgomery County penalizes keeping animals in inadequate space for their number and type with fines of $500 to $1,000 and up to 90 days in jail.5Montgomery County Animal Services and Adoption Center. Montgomery County Animal Control and Anti-Cruelty Laws
What Your Insurer Will Allow
Your homeowners or renters policy adds a limit that has nothing to do with county code. Many insurers keep restricted breed lists and will deny coverage, raise premiums, or exclude liability for certain breeds. Commonly restricted breeds include pit bull terriers, Rottweilers, Doberman pinschers, chow chows, Akitas, German shepherds, mastiffs, and wolf-dog hybrids, among others. The specific list varies by insurer.
Multiple dogs of any breed can also affect coverage. Some policies cap the number of dogs covered under liability, and a bite claim on your record can make renewal difficult or expensive. Before adding a dog, call your insurer to confirm the coverage will not lapse or exclude the new animal. Maryland dog owners already face a presumption of liability for bite injuries, so going without solid liability coverage is a hard risk to justify.
