Short answer
Every dog over four months old in DC needs its own license from DC Health, within 10 days of getting the dog or of it turning four months, and renewed every year. Before applying, your dog must be vaccinated against rabies and distemper. You apply online through DC Health with vaccine records and proof of spaying or neutering where it applies. A fee applies, and the tag must be worn on a collar or harness.
New dog, new home, or a renewal notice
Most people look this up at one of three moments: a new puppy or rescue has just come home, you have moved to DC with your dog, or a license is about to run out. The steps are the same in each case, and most of the work is gathering the right papers before you start.
DC Code § 8-1804(b) says an owner of a dog over the age of four months must get an annual license "before July 1st of each year, or within 10 days of acquiring the dog, or within 10 days after the dog becomes 4 months of age." The same section says the owner must make sure the dog wears "a collar or harness and a license." Each dog needs its own license, and a license cannot be moved from one dog to another.
Rabies and distemper shots come first
DC Code § 8-1803 requires an owner of a dog over four months old to have it vaccinated against rabies and distemper, and § 8-1804(c) says no license may be issued until that is done and any outstanding fines are paid. Cats are covered by the rabies rule too: DC Health says District law requires all cats and dogs over four months old to be vaccinated.
The DC rules give the timing in 24 DCMR 901. A dog must be vaccinated by a licensed veterinarian before it is four months old, or within 15 days after you become its owner or keeper if it was never vaccinated, whichever is later. The rule then calls for a booster 12 months after the first shots and a rabies shot every three years after that. Your vet will tell you which vaccine your dog received and when the next one is due.
Your vet gives you a signed vaccination certificate and a numbered rabies tag. Under 24 DCMR 901.15, the rabies tag must be attached to your dog's or cat's collar or harness and kept there. DC Health also runs free vaccination clinics during the year, where licenses are sold too; its vaccination page lists (202) 535-2323 for clinic information.
What to gather before you apply
DC Health's dog licensing page says applications that do not meet its document rules will not be approved. Having these ready can save a round of back and forth:
- The full vaccination record on the clinic's official letterhead, showing the veterinarian's name and license number, with proof of current rabies and distemper shots.
- Your name on the records. The owner's name on the vaccination records must match the account name on your application. If the records list a partner, parent or roommate instead, DC Health asks you to have your vet reissue them.
- Adoption papers, if your dog was adopted. Upload the shelter's vaccination records with the adoption paperwork, showing the dog's earlier name and you as the new owner. For a dog given to you by a friend or relative, ask your vet for records in your name.
- Proof of spaying or neutering, or DC Health's certification that the requirement was waived. The fee depends on it, and DC Code § 8-1804 sets no fee for a trained service dog.
- Your complete mailing address, with quadrant, ZIP code and apartment or unit number. DC Health warns that a tag will not arrive if the address is incomplete, which matters in DC apartment buildings.
| Step | What DC requires | Where the rule is |
|---|---|---|
| Vaccinate | Rabies and distemper shots from a licensed vet before the license is issued | DC Code §§ 8-1803, 8-1804(c); 24 DCMR 901 |
| Gather records | Full vaccine record on clinic letterhead in your name, plus spay or neuter proof if it applies | DC Health |
| Apply online | Within 10 days of getting your dog or of it turning four months | DC Code § 8-1804(b) |
| Tag on the collar | Dog wears a collar or harness with the license; rabies tag stays attached | DC Code § 8-1804(b); 24 DCMR 901.15 |
| Renew | Every year, ideally 30 days before it expires; same tag number | DC Health |
| Moving to DC | Rabies shot within 15 days of arrival unless already vaccinated with a valid certificate and tag | 24 DCMR 901.17, 901.18 |
How to apply and what happens next
DC Health issues dog licenses through its Division of Animal Services, and new licenses and renewals are submitted online through the link on its Dog Licensing page. DC Health asks you to allow 4 to 6 weeks for it to receive, review and process each application, and the tag is mailed to the address on your account. A fee applies; DC Health lists it on the same page.
Licenses are renewed every year. DC Health asks owners to submit renewals 30 days before the expiration date, with proof of current rabies and distemper vaccination and spay or neuter status. Renewing does not bring a new tag: your old tag number stays valid. If the tag is lost, DC Health has a lost dog tag application, and a replacement fee applies.
For questions while you apply, DC Health's licensing page lists the Division of Animal Services at (877) 672-2174, Monday to Friday, 8:15 am to 4:45 pm. It also says owners with seven or more dogs over four months old need a hobby license as well. Rules and fees change, so check the current page before you apply.
Keep copies where your sitter can find them
Once the license arrives, put the tag on your dog's collar with the rabies tag and an ID tag, and keep a copy of the rabies certificate with your pet care notes. Our guide comparing microchips, ID tags and the DC license explains what each one does if your dog gets loose.
If you use a sitter or walker, those papers help in an emergency. The Petsitting Form on our client forms page asks for your pet's medical condition, your veterinarian's name and contact details, and your consent to take your pet to your vet in an emergency. Our post About Dog Care in Washington D.C. covers everyday care; this guide adds the legal paperwork.
Across the line, and what to do next
If you live in Mount Rainier or elsewhere in Prince George's County, Maryland, DC's license does not apply at home; the county has its own rules, which also cover cats and ferrets. Our guide to pet rules in Mount Rainier and Prince George's County explains them.
Licensing is between you, your vet and DC Health. A pet sitter cannot do it for you, and a vet visit for overdue vaccines comes first. Once your dog is licensed, DC's dog park rules still ask for the right tags, as our DC dog parks guide explains, and our DC leash and dog waste rules guide covers everyday walks. When you are ready for help with walks in Woodridge or nearby, see our dog walking service and the areas we cover.
When to call a vet
Call your vet to schedule rabies and distemper shots if your dog is unvaccinated or overdue, and ask which vaccines your dog needs. If your dog has been bitten or scratched by a wild animal or a stray, call your vet right away; DC Health says a vaccinated pet that is bitten should be examined by a licensed veterinarian immediately. A sick or injured dog goes to a vet before anything else.
Frequently asked questions
- Do I have to license my dog in DC?
- Yes, if your dog is over four months old. DC Code § 8-1804 requires an annual license for each dog, obtained within 10 days of getting the dog or of it turning four months, and the dog must wear a collar or harness with the license. A fee applies, with no fee in the code for a trained service dog. Check DC Health's dog licensing page for current details.
- How long does a DC dog license take?
- DC Health asks owners to allow 4 to 6 weeks for it to receive, review and process each application, and the tag arrives by mail. Applications with incomplete vaccine records, mismatched owner names or a missing unit number may be delayed or not approved. For renewals, DC Health asks you to apply 30 days before your current license expires.
- Do cats need a license in DC?
- DC's license law, DC Code § 8-1804, is written for dogs. Cats still must be vaccinated against rabies under DC law, and 24 DCMR 901.15 says the rabies tag your vet provides must be kept on your cat's collar or harness. Prince George's County, Maryland, is different and does license cats. Check with DC Health if you are unsure.
- I just moved to DC with my dog. What do I need to do?
- Under 24 DCMR 901.17 and 901.18, a dog or cat brought into DC needs a rabies shot within 15 days of arrival unless it already has a valid certificate and tag from a vet. The license law says to license within 10 days of acquiring a dog; to be safe, apply soon after you move. Ask DC Health how the deadline applies to you.
- How do I replace a lost DC dog tag?
- DC Health says to submit a lost dog tag application through its online animal services system, and a replacement fee applies. Renewals do not come with a new tag because your tag number stays the same, so keep the tag on the collar. Until the new tag arrives, a personalized ID tag helps anyone who finds your dog reach you.
