Step-by-Step: Suing a Dog Owner in Massachusetts
Confirm your claim is within Massachusetts's $7,000 limit
Massachusetts's small claims limit is $7,000. If your damages are higher, you can reduce your claim to the limit or file in Massachusetts civil court. Use our Massachusetts Small Claims Limit guide for the full details.
Send a demand letter first
Before suing, check whether the dog owner has homeowner's or renter's insurance — these policies often cover dog bite claims and the insurer may settle without court. Courts in Massachusetts expect plaintiffs to have made a good-faith attempt to resolve the dispute. A demand letter also creates a paper trail and often prompts payment without any court filing.
Gather your evidence
Your case is only as strong as your evidence. Collect everything before filing — see the checklist below for exactly what you need for a dog owner dispute.
Find the right Massachusetts courthouse
File at the Small Claims Session in the Massachusetts county where the dog owner is located, does business, or where the dispute occurred. For businesses, check the Massachusetts Secretary of State website for the correct legal name and registered agent address.
Pay the filing fee ($40–$150)
Massachusetts small claims filing fees range from $40 to $150 depending on your claim amount. Use our Massachusetts Filing Fee Calculator to find the exact amount for your claim. Keep your file-stamped copy.
Serve the defendant properly
The dog owner must be formally notified of the lawsuit. Massachusetts courts provide specific instructions — follow them exactly. Improper service is one of the most common reasons cases are dismissed.
Present your case at the hearing
Bring 3 organized copies of all evidence. Present your case in order: what happened, how much you lost, and why the dog owner is responsible. Most Massachusetts small claims hearings last 15–30 minutes. Stay calm, stick to facts, and let the judge ask questions.

Tips for Winning Your Dog Owner Case in Massachusetts
File an animal control report immediately — this creates an official record and establishes the date, location, and the dog's owner.
In most states, strict liability means the owner is responsible for the first bite even if the dog had never bitten before. Research your state's dog bite law.
Photograph injuries on the day of the attack and every day for 2 weeks — healing progression documents the severity.
Note pain and suffering: small claims can award these in some states. Keep a journal of how the injury affected your daily life.
