If your dog has bitten someone, your immediate options depend on the severity of the bite and what you want to happen next. You may need to fulfill a legal quarantine before you can do anything else, and from there, the path branches: professional behavior help, management changes at home, surrendering to a shelter, rehoming with full disclosure, or in some cases, behavioral euthanasia. Each option has legal and practical realities worth understanding before you decide.
The 10-Day Quarantine Comes First
In most states, a dog that bites a person must be confined for a 10-day observation period to rule out rabies. This is a legal requirement, not optional. If the dog appears clinically normal after 10 days, it’s assumed the dog was not shedding rabies virus at the time of the bite. In New York State, no animal placed in 10-day confinement has ever gone on to develop rabies, which speaks to how reliable this observation window is.
Depending on your local animal control agency, quarantine can happen at home, at a veterinary hospital, or at an animal control facility. Home confinement is sometimes allowed for dogs that are up to date on rabies vaccination and whose owners are considered likely to comply. If the dog was acting abnormally at the time of the bite, observation typically must occur at a veterinary hospital. During this period, you cannot legally transfer or rehome the dog in most jurisdictions. Ohio law, for example, explicitly prohibits removing a biting dog from the county or transferring ownership until quarantine is complete.
A Veterinary Behaviorist for Serious Aggression
If you want to keep your dog and address the biting, the strongest option is a board-certified veterinary behaviorist. These are veterinarians who completed additional residency training specifically in animal behavior. They can diagnose medical causes of aggression (pain, neurological problems, thyroid disorders), prescribe medication when appropriate, and design a behavior modification plan tailored to your dog’s triggers.
This matters because the dog training industry is unregulated. Anyone can call themselves a trainer or even a “behaviorist” without specific credentials. A veterinary behaviorist holds a veterinary degree plus specialized board certification. For a dog that has already broken skin, the difference between qualified and unqualified guidance can be the difference between managing the problem and making it worse. You can search for one through the American College of Veterinary Behaviorists directory, though availability is limited and wait times can be long.
Certified applied animal behaviorists (with a master’s or PhD in animal behavior) and certified professional dog trainers with experience in aggression cases are also reasonable options, particularly if no veterinary behaviorist practices near you. Ask specifically about their experience with bite cases and what methods they use. Avoid anyone who guarantees they can “fix” aggression or relies heavily on punishment-based techniques, which tend to suppress warning signals without addressing the underlying problem.
Management Tools That Reduce Risk
While you work on behavior modification, or if your dog’s aggression can be managed but not fully resolved, practical safety tools make a real difference. A basket muzzle is the most important one. Unlike fabric muzzles, basket muzzles allow dogs to pant, drink water, and take treats while physically preventing bites. Cornell University’s veterinary program recommends keeping training sessions to 5 to 10 minutes, a few times a week, gradually building positive associations with wearing the muzzle before you actually need it in a high-stakes situation.
Beyond muzzles, management includes controlling the environment: baby gates, leashes in the house when visitors arrive, a separate room during gatherings, and clear protocols for anyone who interacts with the dog. Management isn’t a cure, but for many dogs with predictable triggers, it can make the difference between a household that functions safely and one that doesn’t.
Surrendering to a Shelter
Municipal animal shelters and animal control facilities generally accept owner-surrendered dogs, including those with bite histories. However, a bite history significantly affects what happens next. Shelters assess incoming dogs for adoptability, and a documented bite that broke skin makes placement much harder. Some shelters will work to rehome dogs with manageable aggression profiles to experienced adopters. Others may determine the dog is not safe to place.
Legislation in some states now requires shelters and rescue groups to disclose a dog’s known bite history in writing before adoption. New York’s proposed disclosure law, for example, would mandate that any dog over four months old with a history of biting a person and breaking skin must have that information shared with prospective adopters, who would need to sign an acknowledgment. Importantly, a documented bite history would not automatically disqualify a dog from adoption. The goal is informed placement, not blanket exclusion.
If you’re considering surrender, call your local shelter first. Ask what their intake process looks like for dogs with bite histories, whether they have behavior evaluation programs, and what the realistic outcomes are. Some breed-specific rescues or aggression-experienced rescues may also accept dogs that general shelters won’t, though their capacity is limited.
Rehoming Privately
Rehoming a dog with a bite history to a private individual is legally and ethically complicated. Several states require disclosure of known bite history during any transfer of ownership. Even where no specific statute exists, failing to disclose that a dog has bitten someone can expose you to serious civil liability if the dog bites again in its new home.
In 35 states plus Washington, D.C., strict liability laws hold dog owners accountable from the very first bite, with no prior aggressive history required. About 10 states follow some version of the older “one-bite rule,” where liability may depend on whether the owner knew the dog was dangerous. If you rehome a biting dog without disclosure and the new owner gets bitten or someone else does, you could still face legal consequences depending on your state’s framework.
If you do rehome privately, put everything in writing: the circumstances of the bite, what triggers the dog, what management is in place, and what professional guidance you’ve received. The new owner should be someone experienced with reactive or aggressive dogs, ideally someone who has consulted with a behavior professional about what they’re taking on.
When Behavioral Euthanasia Is Considered
This is the option nobody wants to think about, but for some dogs it is the most responsible choice. Behavioral euthanasia is typically considered when a dog’s aggression is severe, unpredictable, or escalating, and when the risk to people or other animals in the household can’t be managed safely. It’s also considered when the dog’s own quality of life is poor, either because chronic anxiety or fear drives the aggression, or because the level of management required (constant confinement, isolation from family life) means the dog isn’t really living well.
Veterinarians and behaviorists evaluate several factors: the severity and frequency of bites, whether bites are escalating in intensity, whether triggers are identifiable or random, the dog’s response to behavior modification and medication, and whether the household can realistically maintain the safety protocols needed. A dog that has delivered multiple bites causing serious injury, or one that bites without any readable warning signals, presents a fundamentally different risk profile than a dog that snapped once in a specific, avoidable situation.
This decision is best made with a veterinary behaviorist or your veterinarian, not alone. Many owners carry enormous guilt, but behaviorists who work with aggression cases consistently emphasize that some dogs are suffering themselves, and that choosing euthanasia to protect both the dog and the people around it is not a failure of love or effort.
Your Legal Exposure as the Owner
Regardless of what you decide to do with your dog, a bite creates legal exposure. In strict liability states, you’re financially responsible for medical bills, lost wages, and other damages from the first bite forward. In states following negligence principles, liability depends on whether you took reasonable steps to prevent the bite, such as leashing, fencing, or muzzling. A handful of one-bite-rule states offer more protection for a first incident, but even there, once a bite is documented, you’re on notice that your dog is dangerous, and any future incident carries much greater legal weight.
Homeowner’s and renter’s insurance policies sometimes cover dog bite liability, but many insurers exclude certain breeds or cancel coverage after a claim. Check your policy now. If your dog has bitten someone and you keep it, increasing your liability coverage or obtaining a specific animal liability policy is worth investigating. Some states also impose requirements after a bite, such as registering the dog as dangerous, maintaining specific fencing, or carrying minimum insurance amounts.
