If your dog is six months or older, state law requires that you obtain a license in the town where you reside. Licensing renewal time is the month of June, but you can license your dog at any time throughout the year. When you come for your first license, you must bring the rabies vaccination certificate issued by your veterinarian. The metal tag is not an acceptable proof of vaccination. The certificate will usually indicate whether the dog has been spayed or neutered, but if not, you'll need to present a separate certificate issued by your veterinarian.
Current fees are $8 for spayed and neutered dogs, and $19 for others.
