All dogs must be licensed by February 28th. You can license online at http://www.townofchelmsford.us/249/Dog-Licenses, license in person at the Clerk's Office or put a check in the mail along with a copy of your dog's current rabies certificate. If you have moved from Chelmsford or if your dog has passed away, please let us know so we can remove you from our database (978) 250-5202.
