Massachusetts Dog Breeder Licensing Requirements

In Massachusetts, kennel licenses are required for owners of commercial boarding, training, breeding, and veterinary kennels, domestic charitable corporation kennels, and private owners of more than four dogs, according to municipal guidance citing Massachusetts General Law Chapter 140, Section 137A. Some towns describe the threshold as five or more dogs, so the exact count can be presented differently at the local level. Separately, under Chapter 140, Section 137, every dog owner must obtain an annual individual license for any dog over six months old (or upon its first rabies vaccination, whichever comes first). A kennel license does not replace the requirement to keep a current rabies certificate for each dog. Anyone breeding dogs for sale should check with their own city or town, because kennel licensing and inspection are handled locally.

You apply for a kennel license through your local town or city clerk's office, not through a single statewide agency. Under Chapter 140, Section 137A, no kennel license will be issued until the kennel has passed an inspection by the local Animal Control Officer, so applying typically involves submitting an application and then scheduling that inspection. You will generally need to provide current rabies certificates for your dogs and pay the applicable municipal fee. Because requirements vary by municipality, contact your town clerk directly for the exact forms and documents. Available sources do not list a single statewide application website or phone number for kennel breeder licensing.

Kennel and dog license fees are set by each municipality, so they vary from town to town. For individual dog licenses, example municipal fees include roughly $6 for a spayed/neutered dog and $10 for an intact dog in one town, and about $15 for an altered dog and $20 for an intact dog in another. Some towns charge late fees, such as a $15.00 late fee after a licensing deadline. Available state sources do not specify a single statewide kennel license fee; state law also directs licensing authorities to issue a kennel license without charge to a qualifying domestic charitable corporation formed to protect animals.

State law requires that a kennel pass an inspection by the local Animal Control Officer before a kennel license is issued, under Chapter 140, Section 137A. Kennels are also expected to keep records, ensure dogs wear tags, and report any on-site injuries. Under the state's animal welfare updates (commonly referred to as "Ollie's Law"), municipalities must send annual kennel reports to MDAR beginning June 2025, and implementing regulations are expected to be completed by June 2026, with an advisory committee sunsetting on December 31, 2026. Available sources do not detail every specific standard an inspector checks or the exact consequences of failing an inspection beyond the license not being issued.

Kennels in Massachusetts are expected to keep records, ensure that dogs wear tags, and report any injuries that happen on site. Municipalities are also now required to send annual kennel reports to MDAR starting June 2025 as part of recent state reforms. Available sources do not specify the exact records a breeder must retain, the required format, or how many years records must be kept. Breeders should confirm current record-keeping details with their municipality and with MDAR as regulations are finalized.

Enforcement is handled largely at the local level through Animal Control Officers and municipal bylaws. For example, one town's bylaw provides that an owner or keeper who fails to comply with an order of the Animal Control Officer or Select Board may be fined fifty dollars ($50.00), with a right to appeal to the District Court under M.G.L. Chapter 140, Section 157. Because a kennel license cannot be issued until an inspection is passed, operating a non-compliant kennel can result in the license being withheld or denied. Available sources do not provide a complete statewide schedule of fines or criminal penalties specific to breeding without a kennel license.
