City Ordinance allows for a family to have no more than 3 dogs about their premises.

The Department of Animal Welfare oversees dog licensing in the State of Maine.  State law requires you to license your dog by December 31st each year.   The license fee is $6.00 for a neutered/spayed dog and $11.00 for an unaltered dog. You may license your dog in person at the Clerk's office or online between October 15 and January 31 without incurring a $25 late fee.  Please have your dog's current rabies vaccination certificate ready at the time of licensing.

All dogs need to be licensed upon reaching the age of 6 months in the town where it resides or after the dog has been with the family for 10 days, if adopted.  If you have a service dog, the licensing fee may be waived.
