Hawaii Dog License Requirements

Updated October 13, 2026 · 2 min read · 2 sources

Short answer

Yes. Hawaii law requires dog licensing (HRS chapter 143), administered by each county, which can set its own fees and rules. Dogs 3 months and older need a license, and state law also requires dogs to be microchipped, with the chip registered and contact details kept current (HRS 143-2, 143-2.2).

Hawaii is one of the states that requires dog licensing by state law, so the basic rule is the same everywhere in the state even though the paperwork is handled locally.

What Hawaii law says

  • The county director of finance issues the license and tag (143-3, 143-4).
  • Dogs under 3 months are not licensed.

  • The default state fee is $4 every second year plus $0.10 for the tag, but counties set their own fees.

How to license a dog in Hawaii

  1. Have your dog vaccinated against rabies by a veterinarian and keep the rabies certificate.
  2. If your dog is spayed or neutered, keep the veterinarian's proof; altered dogs usually pay a lower fee.
  3. Apply through the office named above. Many towns and counties also accept online or mail applications.
  4. Attach the tag to your dog's collar and renew before the deadline to avoid late fees.

Licenses, rabies shots and microchips

Dog licenses and rabies vaccination usually go together: the license office or the veterinarian checks the rabies certificate before a tag is issued. See Hawaii rabies vaccination laws for the required age and booster rules. A license tag helps animal control return a lost dog quickly, and a microchip is a permanent backup if the collar comes off.

What happens if your dog is not licensed?

An unlicensed dog found at large can be picked up by animal control, and getting it back usually means paying impound fees and buying the license. Penalties are listed above where the state statute sets them; local ordinances often add their own fines. Leash and at-large rules are covered in Hawaii leash laws.
