What Is a Dangerous Dog Designation?
A “dangerous” or “vicious” dog designation is a legal classification applied when authorities determine that a dog poses a significant threat to public safety. While the specific criteria vary by state and municipality, common factors include:
Biting or attacking a person or another animal
Displaying aggressive behavior without provocation (growling, lunging, or attempting to bite)
Causing serious injury or death to another pet or livestock
Chronic threatening behavior that alarms or intimidates neighbors

Once a dangerous dog designation is issued, the consequences can be severe. Your dog may be ordered to:
Be muzzled in public
Be kept in a secure, locked enclosure
Undergo behavioral evaluations or mandated training
Be subject to ownership restrictions or bans
In the most extreme cases, be seized or euthanized
Step 1: Understand Your Legal Rights
When your dog is accused of being dangerous, you have the legal right to challenge or appeal the designation. However, you must pay attention to any timeline within which you have to file the appeal.
Key legal rights you have:
A dog owner has rights granted under the state and federal constitutions to procedural due process. Essentially the right to a fair hearing.
Step 2: Request a Hearing or Appeal Immediately
If your dog has been labeled dangerous, act quickly. The first step is to file a formal appeal or request a hearing with the appropriate authority. This could be:
The local Animal Control Board
The Select Board or City Council or Police Department
The District Court if appealing a board decision
Tip: Carefully review the dangerous dog notice, as it will outline the jurisdiction and deadline for filing your appeal. Failing to meet the deadline can result in the designation becoming permanent.
Step 3: Gather Evidence to Challenge the Designation
At your appeal hearing, you have the opportunity to present evidence to challenge the dangerous dog label. Your goal is to demonstrate that your dog is not a public safety threat or that the circumstances were misrepresented.
Crucial evidence to present:
Eyewitness testimony: Neighbors, dog walkers, or others who can confirm your dog’s typical behavior or provide context for the alleged incident.
Veterinary records: Proof of your dog’s health, temperament, and any prior history of aggression (or lack thereof).
Behavioral assessments: A professional dog trainer or behaviorist can provide expert testimony on your dog’s temperament.
Photos, videos, or documentation: Surveillance footage, photos, or documentation showing that your dog was provoked or acting in self-defense.
Character references: Statements from trainers, neighbors, or pet care providers who can attest to your dog’s good behavior.
Step 4: Challenge the Evidence Against Your Dog
In many cases, dangerous dog designations are based on incomplete or inaccurate information. As your legal representative, Boston Dog Lawyers will thoroughly review the evidence presented by animal control or the complainant.
Ways to challenge the evidence:
Questioning the complainant’s credibility: If the complaint was motivated by a neighbor dispute or false allegations, we’ll uncover inconsistencies.
Challenging the circumstances: Proving that the other dog or person provoked the incident or that your dog acted in self-defense.
Highlighting procedural errors: If authorities failed to follow proper procedures (e.g., issuing the notice incorrectly or not providing due process), we’ll use that to your advantage.
Disputing the severity of the incident: Demonstrating that the injuries or damages were minor or accidental, not indicative of a dangerous dog.
Step 5: Consider a Rehabilitation Plan

In some cases, municipalities may offer a compromise rather than enforcing a full dangerous dog designation. This could include:
Mandated training or rehabilitation with a certified behaviorist.
Conditional probationary period to demonstrate improved behavior.
Enhanced safety measures (fencing, leashing) in exchange for lifting or reducing the designation.
Tip: With strong legal advocacy, it’s often possible to negotiate alternative solutions that spare your dog from severe penalties.
Step 6: Take the Case to District Court (if necessary)
If you lose the initial appeal, you may have the right to escalate the case to your local District Court. This is a more formal legal process where you will need a skilled attorney to represent you.
Why it’s worth it:
District Court judges are often more impartial than local boards.
You may have additional legal grounds (such as constitutional violations) to challenge the designation.
The court may consider new evidence or expert testimony not previously presented.
