If your dog is older than six months and living anywhere in Delaware, state law says it needs more than a collar and a leash. It needs a license tag, and skipping that step can cost you far more than the license itself. A missed license can mean a fine that starts at $50 and climbs from there for repeat offenses.
Dog Tag Laws in Delaware changed in a meaningful way in 2025, when the state moved licensing onto a new online platform and folded in a lost-pet recovery service most owners had never had access to before. This guide walks through what the law actually requires, what the tag needs to show, what it costs, and what happens if you skip it.
Are Dog License Tags Required in Delaware?
Yes. Delaware law is unambiguous on this point: dog owners must license their pets, and the license comes with a tag or an approved alternative form of identification. As one New Castle County resource puts it, all dogs over the age of 6 months are required to have a Delaware State Dog License and must display the license tag, and proof of current rabies vaccination is required to obtain a dog license.
This isn’t a local option that some towns choose to skip. It applies statewide, to every dog owner in every county and municipality, regardless of whether the dog ever leaves the yard. The restraint requirements that apply to how you keep your dog at home work alongside this licensing rule, not instead of it.

Three Types of Dog Tags (and Which Ones Delaware Law Actually Means)
Dog owners often lump every metal disc on a collar into one category, but Delaware law actually recognizes a narrower definition than most people assume. Understanding the difference matters if you want to stay compliant without buying tags you don’t legally need.
- Rabies vaccination tags come from your veterinarian after a rabies shot. They prove vaccination status but do not satisfy the state’s licensing requirement on their own.
- License tags are the ones Delaware law is actually talking about. These come from the state’s licensing program and confirm that your dog is registered with Delaware Animal Services.
- Personal ID tags with your name and phone number are a smart accessory, but they’re optional under state law and don’t replace the official license tag.
Under the statute, a licensed dog is issued either a metal tag or an alternative method of identification, such as, but not limited to, a microchip or tattoo. So while most owners will end up with a physical tag, the law technically allows other identification methods for dogs enrolled through a kennel or retail outlet license. The state’s current licensing partner has built extra function into the standard tag: owners who license their dogs receive an assigned tag with a unique code that links directly to a dog’s secure online profile, which anyone who finds a lost pet can reference to create a Found Pet Report.
What Delaware Law Says About Licensing Pet Dogs
Delaware’s licensing framework sits in Title 16 of the Delaware Code, under the state’s Animal Welfare chapter. The statute lays out three distinct license categories rather than a single blanket rule for every dog owner.
| License Type | Who Needs It | Term |
|---|---|---|
| Individual dog owner license | Any dog 6 months or older | Department-determined, typically 1–2 years |
| Kennel license | Anyone keeping more than 4 dogs for show, sale, breeding, or similar purposes | 1 year |
| Retail dog outlet license | Businesses selling dogs at retail | 1 year |
The statute is specific about who applies for each license type. The owner of any dog 6 months of age or older shall apply to the Department or its duly authorized agents on a form prescribed by the Department for an individual dog owner license for such dog. If you keep a larger household of dogs, any person who maintains a kennel wherein more than 4 dogs are kept for show, trial, sale, breeding, or other purposes may apply to the Department for a kennel license in lieu of an individual dog owner license for each dog, which is often simpler and cheaper than licensing each animal separately. If you’re building or operating that kind of multi-dog setup, it’s worth reviewing kennel zoning laws in Delaware before you apply, since local zoning approval can be a separate hurdle from the license itself.
You can read the full current statutory language directly through the Delaware Code, and a consolidated summary of the related dog statutes is also available through the Animal Legal & Historical Center.
Age, Rabies Proof, and When You Must License Your Dog in Delaware
The trigger point for licensing is age, not breed, size, or where the dog lives. Once a dog turns six months old, the clock starts. According to Delaware Animal Services, payment for your license is due within 30 days of the license expiration date, or within 30 days of acquiring a dog over the age of 6 months in the State of Delaware.
Rabies vaccination is the other non-negotiable piece. You cannot get a license without it. A valid rabies vaccination certificate or state authorized exemption certificate is required to obtain a dog license, and the length of license you’re eligible to buy actually depends on how long that vaccination remains valid: pet owners can only purchase a 2 year license if their pet’s rabies vaccination is valid for 13 months or longer from the date of purchase. If your dog’s vaccination is due to expire sooner than that, you’ll be limited to a 1-year license instead.
Rabies requirements in Delaware aren’t limited to dogs, either. If you also keep a ferret, note that Delaware’s ferret ownership rules carry a similar vaccination expectation, and if you want the full picture on how the state treats rabies compliance across pets generally, the pet vaccination laws in Delaware cover that in more depth.
Pro Tip: Upload or bring your rabies certificate at the moment you apply. Delaware’s licensing platform requires you to present it during the purchase process, and a missing certificate is the most common reason applications stall.
How and Where You Get a Dog License Tag in Delaware
Since April 2025, Delaware dog owners have had a single, modernized path to licensing instead of the patchwork of county systems that existed before. The Office of Animal Welfare partnered with DocuPet, an online pet registration provider, to open a new and modernized dog licensing and complimentary HomeSafe 24/7 lost pet service to Delaware dog owners.
You have a few practical options for actually getting the tag:
- Online through the state’s licensing portal at stateofdelaware.docupet.com, where you upload your rabies certificate and pay by card.
- By phone or mail through DocuPet’s support line if you’d rather not complete the process online.
- In person at participating retail and veterinary locations. The state has previously expanded these to include retail locations in Kent and Sussex counties, as well as existing locations in New Castle County such as Brandywine Valley SPCA in New Castle, New London Veterinary Hospital in Newark, Delaware Humane Association in Wilmington, and the New Castle County Government Center.
Keep in mind that online orders carry a processing surcharge: a processing fee is applied on license purchases at a rate of 2.65% plus $0.25 per transaction. That’s a small cost but worth knowing before you’re at checkout.
Must Your Dog Wear the License Tag on Its Collar in Delaware?
Yes, with a few narrow exceptions. The statute is direct about the physical requirement: in the event a dog tag is issued, the tag shall be of a design to be adopted by the County, and shall be affixed to the collar by the owner of such dog. In practical terms, that means the tag needs to actually be on the dog, not sitting in a drawer.
There are two recognized exceptions worth knowing:
- Kenneled dogs: dog collars with associated tags may be removed and need not be worn at all times when the dog is licensed as a kennel or retail dog outlet and is housed in an enclosure or a pen, but if the collar has been removed, a valid dog tag and license must be readily available for review by a dog control agent.
- Hunting dogs: dogs engaged in the act of hunting are exempted from wearing county tags while they are in the act of hunting, but must have some means of valid identification on the dog.
If you hunt with your dog regularly, it’s worth cross-referencing this exemption against the broader hunting laws in Delaware and, if waterfowl hunting is part of your routine, the specific duck hunting laws in Delaware, since dog-handling rules in the field sometimes carry their own conditions beyond the tag exemption itself.
Fees, Renewals, Spay/Neuter Discounts, and Exemptions in Delaware
Delaware’s fee structure rewards spaying and neutering, and it builds in specific breaks for seniors, service dogs, and veterans. Here’s the current published fee schedule from Delaware Animal Services:
| License Category | 1-Year Fee | 2-Year Fee |
|---|---|---|
| Spayed or neutered dog | $10 | $20 |
| Unaltered dog | $15 | $30 |
| Senior (65+) with altered dog | $7 | $14 |
| Replacement tag | $5 | |
| Late fee (after 30 days) | $7 | |
Licenses are valid for 1 or 2 years from date of purchase, and a 2-year license may be purchased if there is more than 1 year left on the rabies vaccination. Seniors get a break too, but only under specific conditions: those aged 65 and older may qualify for a senior citizen rate, though the pet must be spayed or neutered to receive it.
A handful of dogs are exempt from the fee entirely. Per Delaware law, the fee is waived for seeing eye, guide or lead dogs, or dogs who have former U.S. military service. That exemption applies to the fee, not to the licensing requirement itself; even exempt dogs still need to go through the application process, including rabies documentation. If you rely on a service or support animal that doesn’t fit the guide-dog category, it’s worth checking the separate rules covered in emotional support animal laws in Delaware, since that designation doesn’t automatically qualify a dog for the same fee waiver.
City and County Rules That Still Control in Delaware
Delaware licensing wasn’t always a single statewide system. Before 2016, counties and the City of Wilmington each ran their own licensing programs with their own fees and forms. The Office of Animal Welfare assumed dog licensing administration from the counties and City of Wilmington beginning January 1, 2016, and created a statewide license for that year, while honoring the expiration dates of existing county and city licenses.
That transition still echoes in the current law. Individual, retail, or kennel licenses previously issued by a county or the City of Wilmington remain valid until their predetermined expiration dates, so if you have an older tag, it isn’t automatically invalid, but you’ll need to switch to the statewide DocuPet system once it expires.
Local ordinances still layer additional requirements on top of the state license, particularly around leashing, restraint, and kennel operations. Sussex County’s own leash ordinance, for example, mirrors the state’s exemption language almost word for word: the license fee shall not be required to be paid when the dog is one which qualifies as a seeing eye, lead or guide dog or as a dog which has previously served in a branch of the United States armed forces. Zoning and kennel-density rules also vary meaningfully by county and municipality, which matters if you’re operating anything beyond a typical household, including situations covered under pit bull laws in Delaware or Rottweiler laws in Delaware, where some municipalities impose additional insurance or containment conditions alongside standard licensing.
Lost Tags, Moving, and Replacing a License in Delaware
Tags get knocked off collars, chewed up, or lost in the yard more often than owners expect. Delaware’s system makes replacement simple: a replacement tag is available for a $5.00 fee. If your dog’s tag was one of the newer DocuPet-issued versions, note that each pet only receives one free tag with their first license via DocuPet, and this tag doesn’t expire, so a lost tag replacement is a paid, standalone transaction rather than part of your annual renewal.
The tag system also doubles as a recovery tool if your dog actually goes missing. Anyone who finds a lost pet can reference the code on the tag to create a Found Pet Report in seconds, owners can create Lost Pet Reports as soon as they realize their pet has gone missing, and DocuPet’s dedicated dispatch staff is available 24/7 to reunite lost pets with their families. That’s a meaningful upgrade from the older, static metal tags most owners are used to.
If you’re relocating to Delaware with a dog already licensed elsewhere, or moving your dog into the state from out of state, licensing works on Delaware residency, not where the dog was originally registered. Review the pet import laws in Delaware alongside licensing, since import documentation and licensing are separate requirements that both apply once your dog is living in the state.
Penalties for Unlicensed Dogs in Delaware
The financial argument for licensing is straightforward once you compare the cost of compliance to the cost of getting caught without it. Delaware Animal Services puts it plainly: the cost of the license is far less than the penalty for being caught without one, and if a state animal welfare enforcement officer finds your dog without a license, you can end up paying a fine of $50, more for repeat offenses.
Common Mistake: Assuming a fine only applies if your dog gets loose or picked up by animal control. Enforcement officers can issue citations during routine checks, not just after a runaway incident.
Kennel operators face steeper consequences for skipping their license entirely. According to licensing guidance for breeders and multi-dog owners, failure to get a kennel license when required can result in fines ranging from $50 to $500. That range reflects the scale difference between a single unlicensed pet and a facility housing multiple dogs without proper oversight.
How to Find Your Local Licensing Authority in Delaware
Even though licensing runs through a single statewide system now, day-to-day animal control enforcement still has a local face. Animal control is the statewide responsibility of the Kent County SPCA, and all animal control issues in all counties fall under the authority and enforcement of Delaware Animal Control officers and the Kent County SPCA.
For licensing itself, you have several direct contact points:
- Online licensing: stateofdelaware.docupet.com
- DocuPet support: licensing questions can go to DocuPet directly, and Delaware Animal Services can be reached for eligibility questions at [email protected]
- Delaware Office of Animal Welfare: animalservices.delaware.gov for individual, kennel, and retail dog outlet license details
If your situation involves anything beyond a single household pet, whether that’s a kennel operation, a breeding program, or a multi-species property, it’s worth checking how licensing intersects with other Delaware animal ownership rules before you assume one license covers everything, since requirements for other animals kept on the same property or additional right-to-farm protections can carry separate compliance steps entirely.
Staying licensed isn’t complicated once you know the timeline: renew before expiration, keep rabies proof current, and make sure the tag actually stays on the collar. It’s a small annual task that saves both money and stress if your dog ever slips out the gate.
