Remember, all New Hampshire dogs must be licensed with their town clerks by May 1, 2008. You must present a valid rabies certificate to qualify for licensure. Generally, it is a bit less expensive to license a neutered dog (male or female) than an intact dog. Town clerks will accept either a spay or neuter certificate from your veterinarian, or the statement on your rabies certificate indicating your dog’s gender as neutered male or spayed female. You may want to check with your town clerk; I have heard that some clerks require that your dog’s rabies vaccination be valid for at least 6 more months in order to issue a license.
According to New Hampshire state law, all dogs, cats, ferrets and wolf-hybrids must be vaccinated for rabies, although only dogs are required to be licensed at this time.
