New Hampshire Dog License Requirements

Short answer

Yes. New Hampshire requires every dog 4 months or older to be licensed every year with the town or city clerk; the license year runs May 1 to April 30 (RSA 466:1). Fees are $4.50 for spayed or neutered dogs and $7 for unaltered dogs 7 months and older, plus a $1.75 population control fee. Proof of rabies vaccination is required.

New Hampshire 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.

How to license a dog in New Hampshire

  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 New Hampshire 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 New Hampshire leash laws.
