From the City of Cambridge, March 14, 2016: Cambridge residents can now apply for or renew their dog’s license online by clicking here. State law requires that all dogs over six months have a current license; they are good from from April 1 to March 31 and must be renewed annually. The fee for a spayed or neutered dog is $10, or $30 for a dog that is not spayed or neutered. The fine for an unlicensed dog is $50.

To get a license, owners must have a current rabies vaccination. Dogs can be vaccinated at the veterinarian’s office, at clinics held at some pet stores or at the city’s periodic low-cost clinics, where the fee is $15 per dog and microchipping is also available for $20. (Dog licenses can be a ticket home if your dog is lost, since the number on the tag can be traced back to the owner to help for a safe return, and microchipping can provide added protection.) The next clinic will be held from 9 to 11 a.m. April 2 at the city’s Department of Public Works, 147 Hampshire St., in the Wellington-Harrington neighborhood.
