Ohio Governor Mike DeWine officially signed House Bill 247 into law on Friday, marking a historic shift in how the state handles aggressive animals and owner accountability.
Known as “Avery’s Law,” the legislation aims to close long-standing loopholes that allowed dangerous animals to remain in neighborhoods after multiple incidents.
DeWine finalized the legislative package this week to ensure the Ohio dog law provides better protection for residents across the state.
What to expect in the updated Ohio dog law?
The new regulations, scheduled to take effect on March 18, 2026, were inspired by 12-year-old Avery Russell, according to the Ohio House of Representatives. Russell, a Reynoldsburg resident, survived a brutal mauling by two dogs in June 2024. The legislation empowers local officials to intervene much sooner when a dog shows signs of aggression.
Ohio’s pre-existing legal system already allowed action after a first attack — but advocates argued it didn’t provide sufficient procedural clarity or enforcement authority for officials. The new law aims to fix those gaps.
It creates a clearer framework for classifying dogs based on their behavior and history. According to Tyack Law Firm, these classifications are nuisance, dangerous, and vicious. These now carry heavy legal weight and specific insurance mandates.
Local leaders in Cincinnati are already preparing for the transition. The Hamilton County Dog Warden’s office expects an increase in registration filings as the March deadline approaches. This legislative overhaul represents the most significant change to animal control in the state in over a decade.
Enhanced enforcement under the Ohio dog law
One of the most impactful provisions of the Ohio dog law involves the immediate seizure of animals. Previously, dog wardens often lacked the legal authority to remove a dog from a home immediately following an unprovoked attack. Now, authorities can seize a dog at the scene of an incident if it results in injury.
This change prevents further attacks while the legal process determines the animal’s future.
The law also mandates the humane destruction of any dog that kills or seriously injures a human. While the law requires due process, the standard for euthanasia is now much clearer in cases of extreme violence. According to a report by WFMJ News, these measures ensure that victims do not have to live in fear of a repeat attack from the same animal.
State Representative Kevin Miller, the bill’s primary sponsor, noted that the state’s previous rules were “outdated and inadequate.”
“The legislation updates Ohio’s outdated and inadequate dangerous/viscous dog laws. It gives our dog warden’s the tools needed to keep our communities safe and holds irresponsible dog owned accountable when they fail to contain these dangerous animals,” said Miller.
The new framework gives wardens the tools they need to protect the public without facing bureaucratic hurdles. These enforcement powers extend to investigating complaints of dogs running loose or threatening neighbors.
Strict requirements for dangerous dog owners
Owners of dogs classified as dangerous or vicious face several new hurdles under the Ohio dog law. These owners must now maintain at least $100,000 in liability insurance to cover potential medical expenses for victims. Failure to maintain this insurance can result in criminal charges and the removal of the animal.
Additional requirements for these specific classifications include:
- Paying a $100 special registration fee annually.
- Posting clearly visible “Dangerous Dog” warning signs on the property.
- Providing proof of spaying or neutering the animal.
- Updating the county auditor within 10 days of moving residences.
The insurance mandate addresses a common problem where victims of attacks are left with massive medical bills and no way to collect damages. By requiring a minimum of $100,000 in coverage, the state ensures a baseline of financial accountability for high-risk pets.
Criminal penalties and owner accountability
The Ohio dog law significantly increases the criminal penalties for negligent owners. If a dog previously designated as “vicious” kills a person, the owner can now face a fourth-degree felony charge. This marks a major escalation from the minor misdemeanors and small fines that were common under previous statutes.
In the case of Avery Russell, the owner of the dogs that attacked her received only four days in jail and a $450 fine. Her mother, Drew Russell, argued that such light sentences failed to reflect the life-altering trauma caused by the attack. The new law seeks to rectify this by aligning the punishment with the severity of the negligence.
Authorities also introduced a mandatory reporting system for medical professionals. Healthcare providers and veterinarians must now report dog bites to local health authorities within 24 hours. This data will help the state track “problem” animals across different jurisdictions, preventing owners from simply moving to a new county to avoid a dangerous dog designation.
Protecting the rights of responsible pet owners
While the Ohio dog law is strict, it includes vital protections for responsible owners and their pets. The legislation features a “self-defense” clause that protects dogs acting to defend their owners or property. A dog cannot be designated as dangerous or vicious if it was provoked or if it was protecting its home against an intruder.
This distinction ensures that guard dogs and family pets are not unfairly penalized for natural defensive behaviors. Lawmakers worked closely with animal welfare groups to balance public safety with the rights of pet owners. The goal is to target “irresponsible” ownership rather than the animals themselves.
For Cincinnati residents, this means that most household pets will see no change in their daily lives. The focus remains squarely on the small percentage of animals that pose a genuine threat to the community. Local officials encourage all residents to ensure their current registrations are up to date to avoid confusion when the new rules take effect.
Looking toward the 2026 implementation
As Cincinnati prepares for the March 18, 2026, implementation date, educational efforts are underway. Local shelters and the Hamilton County Auditor’s office plan to host workshops to explain the registration changes. Understanding these rules is essential for every pet owner in the Tri-State area.
