Ohio has a long and complicated history with puppy mills. In 2024, Ohio was ranked the second worst state for inhumane puppy mills, with 20 of the nation’s worst facilities located within its borders. If you live in Ohio, plan to buy a puppy, or suspect a breeding operation near you is mistreating animals, understanding how the law works is an important first step.

Ohio operates under a specific legal framework for commercial dog breeding that defines who must be licensed, what standards of care apply, and what happens when those standards are broken. This guide walks you through each layer of that framework — from the state’s legal definition of a puppy mill to the penalties breeders face for violations.

What Is Considered a Puppy Mill in Ohio

Ohio law does not use the term “puppy mill” in its statutes. Instead, the legal system works through a defined category called a high volume breeder. Definitions are important in understanding Ohio’s puppy mill laws because only those establishments or individuals who satisfy the definitions of a “High Volume Breeder,” “Dog Broker,” or “Pet Store” are subject to the Ohio laws that license and regulate the commercial dog breeding industry.

Under Ohio law, a “high volume breeder” is defined as an establishment that keeps, houses, and maintains six or more breeding dogs and: (1) sells five or more adult dogs or puppies in any calendar year to dog brokers or pet stores; (2) sells forty or more puppies in any calendar year to the public; or (3) keeps, houses, and maintains, at any given time in a calendar year, more than forty puppies that are under four months of age, that have been bred on the premises of the establishment, and that have been primarily kept, housed, and maintained from birth on the premises of the establishment.

Ohio law defines a breeding dog as an unspayed adult female dog that is used primarily for producing offspring. This means the six-dog threshold is counted only among unspayed adult females — not all dogs on the property.

Key Insight: If a breeding operation falls below these numerical thresholds, it is not classified as a high volume breeder and is not subject to Ohio’s commercial breeder licensing requirements — even if conditions at the facility are poor.

Informally, puppy mills are inhumane breeding facilities where dogs are kept in poor conditions, bred excessively, and sold to pet stores or directly to consumers, with animals suffering from neglect, lack of proper medical care, and harsh living environments. Ohio’s legal framework attempts to address these conditions through the high volume breeder classification, but advocates note that operations below the threshold can still cause serious harm. If you are researching emotional support animal laws in Ohio, the distinction between licensed and unlicensed breeders can also matter when sourcing a trained animal.

Federal Law and How It Applies in Ohio

The Animal Welfare Act (AWA) is the only federal law that regulates the treatment of dogs in commercial breeding facilities. This piece of legislation sets forth minimum standards of care for dogs in commercial breeding facilities, such as standards for cage space, flooring, veterinary care, and sanitation.

The AWA is administered and enforced by the United States Department of Agriculture (USDA). Breeders that sell their animals sight unseen are licensed and inspected by the USDA, but facilities on the local level are governed by a patchwork of state laws that vary widely in their licensing, inspections, and enforcement. This means that a breeder in Ohio may hold a valid USDA license and still be operating in ways that violate Ohio’s own state standards — or vice versa.

Many of these facilities are USDA licensed, meaning they can legally sell puppies to pet stores and online consumers — even while accumulating documented animal care violations.

Important Note: Federal AWA standards represent a floor, not a ceiling. Ohio’s state law can — and does — impose requirements that go beyond what the AWA mandates. When buying a puppy, a USDA license alone does not guarantee the animal was raised in humane conditions.

The USDA’s enforcement of the AWA has been criticized as extremely lax and ineffective, which allows for harsh treatment of commercially bred dogs to persist. Ohio’s state-level regulations were designed in part to fill this gap, though enforcement challenges remain at the state level as well. For a broader look at how Ohio Revised Code Chapter 956 interacts with federal standards, the Animal Legal and Historical Center maintains the full statutory text.

Does Ohio Have Puppy Mill Laws

Yes — Ohio has some of the most detailed commercial dog breeding laws in the country. The foundation of the current framework is House Bill 506, signed into law in 2018. Governor John Kasich signed into law anti-puppy-mill legislation that implements major reforms designed to improve the lives of breeding dogs, including a ban on some of the most cruel practices used by commercial dog breeders, like stacking dogs in cages one on top of the other, and keeping animals in cages with wire flooring.

Standards of care in the law allow dogs more space to move around freely in clean enclosures with solid flooring, have proper food, water, exercise, and socialization, and receive annual veterinary exams. There is also a limit on the number of times a mother dog can be bred. Specifically, if the dog is a female, the law ensures that the dog does not produce more than eight litters in its lifetime.

This law not only protects breeding dogs but serves to protect the public as well, because commercial breeders, regardless of where they are located, will have to adhere to these humane standards if they sell to Ohio consumers. That out-of-state reach is significant — it means an Ohio pet store cannot sidestep the law simply by sourcing puppies from a breeder in another state.

Despite this legal progress, advocates point out that enforcement has lagged. Inspections are typically announced in advance, penalties are often minimal, and only a handful of inspectors are tasked with overseeing hundreds of commercial breeders statewide — as a result, repeat violations are common. As of early 2026, Senate Bill 232 was introduced to reinstate unannounced inspections of commercial breeders, since in 2023, inspections shifted to being announced in advance — giving facilities time to prepare and potentially mask ongoing conditions.

Commercial Breeder Licensing and Inspection Requirements in Ohio

If you operate or plan to operate a high volume breeding facility in Ohio, the licensing process involves both state and county requirements.

Ohio has a two-tier licensing system for dog breeders. Anyone operating a kennel in Ohio must first obtain a county kennel license from their local county auditor, with fees typically ranging from $80 to $100 per year depending on the county. Second, high-volume commercial dog breeders must obtain a state license from the Ohio Department of Agriculture under Ohio Revised Code Chapter 956.

At the state level, the application process is detailed. The application must include an affidavit signed under oath stating the number of adult dogs kept at the location, an estimate of the number of puppies to be kept and litters to be produced during the term of the license, and photographic evidence documenting the facilities where dogs will be kept, housed, and maintained.

In order to be licensed, the breeder must complete an application that includes a background check to assure that the breeder has not had any convictions or guilty pleas to any offenses relating to domestic animals or domestic violence. The breeder is required to pay an annual fee based on the anticipated number of dogs and puppies the breeder expects to sell, with annual fees ranging from $150 for at least 40 puppies through $750 for 351 or more puppies.

Pro Tip: If you are proposing to open a new high volume breeding facility, Ohio law requires you to submit your application at least 90 days before commencing operations. Do not wait until you are ready to begin — the inspection and approval process takes time.

Once licensed, high volume breeders must comply with requirements governing housing, socialization, nutrition, exercise, grooming, health care, biosecurity, disease control, waste management, whelping, and transportation.

On the inspection side, high-volume dog breeders licensed by the state are subject to annual inspections by the Ohio Department of Agriculture to ensure compliance with state laws governing care, housing, and treatment of breeding dogs and puppies. These inspections examine facility conditions including adequate space, proper ventilation, temperature control, sanitation, access to clean water, appropriate nutrition, and veterinary care.

Record-keeping obligations are also significant. All adult dogs or puppies 16 weeks of age or older in the possession of a high volume breeder or dog broker must be identified by either an official USDA identification tag, a distinctive and legible tattoo marking, or a microchip. These identification requirements make it easier for inspectors to track individual animals and verify that records match what is actually on the premises.

Pet Store Sale Restrictions in Ohio

The regulation of pet stores is a matter of general statewide interest that requires statewide regulation. Sections 956.19 to 956.23 of the Ohio Revised Code constitute a comprehensive plan with respect to all aspects of the regulation of pet stores. Accordingly, it is the intent of the General Assembly to preempt any local ordinance, resolution, or other law adopted to regulate the sale, delivery, barter, auction, broker, or transfer of a dog from a pet store. This means individual cities and counties in Ohio cannot pass their own, stricter pet store sourcing laws.

Ohio law imposes meaningful restrictions on what pet stores can and cannot do when selling dogs. No owner, manager, or employee of a pet store shall negligently sell, deliver, barter, auction, broker, give away, or transfer a dog that does not have a permanent implanted identification microchip, or sell a dog to a person who is younger than eighteen years of age as verified by valid photo identification.

When a dog is sourced from a breeder or broker, disclosure requirements kick in. A written certification must be provided to the buyer prior to the transaction, and it must include the United States Department of Agriculture license number of the breeder that bred the dog, if applicable, and a copy of the most current USDA inspection report for the breeder, as well as a document signed by an accredited veterinarian describing any known disease, illness, or congenital or hereditary condition that adversely affects the health of the dog at the time of examination.

A pet store must keep a copy of this certification for a period of at least two years from the date of the acquisition, and the owner or manager must make the copy available for inspection or duplication by the Department of Agriculture.

Common Mistake: Many buyers assume that a pet store puppy comes with a clean bill of health simply because the store is licensed. Ohio law requires disclosure of known health conditions, but it does not guarantee that all conditions have been identified. Always request the full written certification and the breeder’s USDA inspection history before purchasing.

Ohio does not currently ban pet stores from selling dogs sourced from commercial breeders the way some other states do. Ohio is among the states that require pet stores to be licensed and regularly inspected, but sourcing restrictions remain tied to breeder qualification standards rather than an outright prohibition on commercially bred puppies.

How to Report a Suspected Puppy Mill in Ohio

If you believe a breeding operation near you is violating Ohio law, you have several reporting avenues available. Taking action is important — when inspections approach, puppy mills often offload dogs and puppies to shelters and rescues, overwhelming systems that are already stretched thin, and many of these dogs arrive with serious, lifelong health and behavioral issues caused by neglect and poor breeding.

Here is a breakdown of where to report and what each channel handles:

Ohio Department of Agriculture (ODA): File a Commercial Dog Breeding Complaint Form with the Ohio Department of Agriculture, which is the regulatory authority for Commercial Dog Breeders. This is the primary channel for complaints about licensed high volume breeders.

Local animal control or county dog warden: County dog warden departments are responsible for bringing breeders into compliance with kennel licensing requirements and ensuring that all dogs have access to shelter, are given adequate food and water, and have not been subject to a cruelty violation as defined in Ohio Revised Code 1717.

USDA Animal Care: Anyone with concerns about a puppy mill or potential animal welfare violations can also report their concerns to the USDA. This is particularly relevant for facilities that hold a federal license.

Local humane organizations: If you suspect a facility is operating as a puppy mill or is engaging in animal abuse, you can report it to local animal control authorities or humane organizations. Many municipalities have hotlines or online forms for reporting suspected abuse or neglect.

When making a report, document as much as you can before contacting authorities. Note the address and name of the facility if known, the approximate number of dogs visible, and any specific conditions you observed — such as overcrowded enclosures, lack of water, or visible injuries. Researchers behind the Horrible Hundred report encourage anyone looking to adopt a puppy to avoid any breeder who cannot be visited in person. If a breeder refuses an in-person visit, that itself is a warning sign worth reporting.

Penalties for Puppy Mill Violations in Ohio

Ohio law provides for both administrative and criminal consequences when commercial breeding violations occur. The specific penalty depends on the nature and severity of the violation.

On the administrative side, the Ohio Department of Agriculture has authority to take direct action against licensed breeders. The director of agriculture shall deny a license application if the applicant has violated any provision of the chapter if the violation materially threatens the health or welfare of a dog, or if the applicant has been convicted of or pleaded guilty to a disqualifying offense. The director may also suspend or revoke a license issued under this chapter for violation of any provision of the chapter or a rule adopted under it if the violation materially threatens the health and welfare of a dog.

Background history matters significantly. The director shall deny a license application if the applicant, in the past twenty years, has been convicted of or pleaded guilty to violating animal cruelty statutes under the Ohio Revised Code or an equivalent municipal ordinance.

Civil penalties are also available. Any person assessed a civil penalty under the chapter shall pay the amount prescribed to the Department of Agriculture, and the department shall remit all money collected to the treasurer of state for deposit in the commercial dog breeding fund.

Beyond administrative action, breeding operations that mistreat dogs can face criminal charges under Ohio’s companion animal cruelty statutes. Dogs are classified as companion animals under Ohio law, which means they receive protections under Ohio Revised Code Section 959.131. Violations of those companion animal protections are treated as strict liability offenses, meaning prosecutors do not need to prove intent — only that the prohibited conduct occurred.

Important Note: Ohio’s cruelty statutes apply to dogs regardless of where they are kept, including inside pet stores and commercial breeding facilities. This means that even a licensed high volume breeder can face criminal animal cruelty charges if conditions at the facility rise to that level.

Despite these tools, enforcement has been an ongoing challenge. Inspections are typically announced in advance, penalties are often minimal, and only a handful of inspectors are tasked with overseeing hundreds of commercial breeders statewide. Proposed legislation like Senate Bill 232 aims to address this by reinstating unannounced inspections and strengthening the penalty structure. Violations documented in recent inspection reports have included leaving dogs in overly hot or freezing temperatures, negligent healthcare, selling underage puppies, and in some cases animal deaths, with at least one breeder cited three times for using unacceptable instruments to tail dock puppies.

If you are a new puppy owner and want to understand your responsibilities under Ohio law once your dog comes home, our guides on leash laws in Ohio and how to train your puppy are good starting points. You may also want to read about when a puppy can eat dry food to ensure your new dog gets the right nutritional start after coming from any breeding environment.

Ohio’s commercial dog breeding laws represent a meaningful step forward from where the state stood before 2018, but the gap between what the law requires and what is actually enforced remains a concern for animal welfare advocates. Staying informed, asking the right questions before buying a puppy, and knowing how to report suspected violations are among the most practical things you can do to support better outcomes for dogs in Ohio.
