District of Columbia Dangerous Dog Law
In the District of Columbia, a dog that bites a person is quarantined for 10 days, usually at home, whatever its vaccination status12. If the bite caused broken bones or lacerations needing multiple sutures, DC Health can declare the dog dangerous; a lesser unprovoked injury can make it potentially dangerous15. The owner has 15 business days to request a hearing16.

What happens right after a bite?
DC Health asks that every animal bite be reported to DC Animal Care and Control at (202) 888-738714. The duty is broad: under 22-B DCMR § 203.1, any person who has reason to suspect a rabies exposure from a bite must report it immediately by phone to DC Health, and police, animal control and private vets must pass on reports they receive12.
Once DC Health notifies you, your dog must be quarantined for 10 days, even if its rabies shots are current12. Usually that means at home; DC Health can order confinement elsewhere at your expense12. A veterinarian or an official examines the dog on the first and last days, and you pay for those exams12. During the quarantine you may not vaccinate the dog against rabies, give it away, take it out of the District or have it put down12. If it falls ill or escapes, call animal control at once; if it shows signs of rabies it is euthanized and tested1213.
Every dog over four months old must already be vaccinated against rabies and distemper22. An unvaccinated dog is quarantined for the same 10 days, and its owner is also in breach of § 8-180322.
How is a dog declared dangerous?
Chapter 19 of Title 8 of the D.C. Code, first enacted in 1988 and rewritten in 2008, has two classes15:
- Potentially dangerous dog: without provocation, chases or menaces a person or domestic animal and causes an injury less than serious; approaches as if to attack or shows a propensity to attack without provocation; or is impounded running at large three or more times in 12 months.
- Dangerous dog: without provocation causes a serious injury, meaning broken bones or lacerations requiring multiple sutures or cosmetic surgery, to a person or domestic animal; or repeats potentially dangerous behavior after being declared potentially dangerous.
Police dogs on duty are excluded from both classes15.
The Mayor, through DC Health and the animal control agency, investigates and must weigh evidence of provocation or justification16. A dog cannot be declared either class if the person it injured was willfully trespassing on the owner's premises, or was provoking, tormenting, abusing or assaulting it (now or repeatedly in the past). The same applies if the dog was responding to injury, protecting itself or its puppies, or defending a person nearby from attack16. The owner carries the burden of proving one of these exceptions16.
Hearing and appeal deadlines
Notice of the determination is served personally, posted or mailed. You then have 15 business days to file a written appeal and request a hearing16. The hearing, open to the public, is held 5 to 10 business days after notice of it. You can present evidence of provocation; the case can be decided even if you do not appear16. The written decision follows within 5 days, and you have 5 days from the hearing officer's order to petition the D.C. Superior Court16. A court order vacating a finding does not stop a new determination if the dog misbehaves again16.
If there is probable cause that the dog is dangerous and threatens public safety, the Mayor can get a search warrant and impound it pending the case16. You pay the impound, care and veterinary costs unless the dog is cleared. If they are not paid within 5 days of a final determination, ownership passes to the animal control agency16.
What must the owner of a declared dog do?
You must obtain a certificate of registration and meet every condition in the table above: be 18 or older, license and vaccinate the dog, spay or neuter and microchip it, keep a proper enclosure, pay the annual fee, and get written consent from your landlord or homeowners' association18. A dangerous dog also needs a warning sign readable from 50 feet18. A potentially dangerous dog may leave its enclosure only on a leash no longer than 4 feet held by a responsible person. A dangerous dog must stay on your property except for veterinary care, and then must be caged, or muzzled and on a 4-foot leash19. You must tell the Mayor within 24 hours if the dog gets loose, attacks a person or animal, dies, or is sold or given away, and you may not take a dangerous dog out of the District without written permission19. District law does not require liability insurance or a bond18.
When can the dog be euthanized?
The Mayor may humanely destroy a declared dog only on the grounds in § 8-1903: it was found to threaten public safety if returned, you did not register it or follow the confinement and special conditions, you did not repay impound costs, or you forfeited it17. An impounded dog found to pose a threat is returned only after you register it and agree to every condition17.
Fines and criminal penalties
Breaking the registration or confinement rules is a misdemeanor prosecuted by the Attorney General: up to $500 and 90 days in jail for a first offense, up to $1,000 and 90 days for later ones20. If a dangerous or potentially dangerous dog kills or seriously injures a person or domestic animal without provocation, the owner can be fined up to $10,00020. Letting any dog run at large carries a fine of up to $500231.
Does D.C. restrict breeds?
No. Both classes turn on what the dog did, not its breed15. The Court of Appeals has refused to treat pit bulls as inherently dangerous, noting that the Council chose a behavior-based process instead of a ban10. For civil liability for the bite itself, see District of Columbia dog bite law and my dog bit someone.

D.C. rules in brief
Reporting. Under 22-B DCMR § 203.1, a veterinarian or any other person who has reason to suspect that a person was potentially exposed to rabies by a bite must report it immediately by phone to DC Health, followed by a written report12. A report made to the police, to Animal Care and Control or to a private veterinary clinic must be passed on to DC Health at once12. DC Health asks that bites be reported to DC Animal Care and Control at (202) 888-7387 or through its online Animal Bite Report Form1314.
Euthanasia. The Mayor, acting through District animal control officials, may humanely destroy a dog found to be a threat to public safety if returned, or whose owner fails to register it, follow the confinement rules, pay impound costs within 5 days of a final determination, or surrenders it1716. The owner can appeal a determination within 15 business days and then petition the Superior Court within 5 days of the hearing decision16.
Criminal penalties. Violating the registration or confinement rules for a dangerous or potentially dangerous dog is a misdemeanor: up to $500 and 90 days for a first offense, up to $1,000 and 90 days after that20. If a declared dog kills or seriously injures a person without provocation, the owner can be fined up to $10,00020. See dog bite criminal charges.
Breed rules. The District has no county or city governments below the Council, and its dangerous-dog law judges dogs by behavior, not breed; 1996 emergency acts naming pit bulls and Rottweilers were temporary and lapsed1510.
