Ohio Dog Breeder Licensing Requirements

In Ohio, there are two layers of licensing for people who breed dogs. First, under Ohio Revised Code Chapter 955, every dog three months of age or older must be registered each year, and anyone who keeps adult dogs to breed them for sale, exchange, or lease (and is not a licensed high volume breeder) must register a kennel with the County Auditor. Second, high-volume commercial dog breeders are licensed and regulated by the Ohio Department of Agriculture under Ohio Revised Code Chapter 956. Under R.C. 956.01, a high volume breeder is an establishment with 6 or more breeding dogs that sells 5 or more dogs a year to dog brokers or pet stores, sells 40 or more puppies a year to the public, or keeps more than 40 puppies under 4 months old that were bred on site at any one time. Breeders who keep more than four breeding females and sell dogs sight unseen or at wholesale may also need a federal USDA license under the Animal Welfare Act, which is separate from Ohio's rules. If you are unsure which category you fall into, check with both your County Auditor and the Ohio Department of Agriculture.

To license individual dogs and to get a county kennel license, you apply through your County Auditor, usually during the renewal period that runs from December 1 through January 31 each year. Kennel licenses follow a separate registration process from standard annual dog registration, and some counties let you download a blank kennel license application form from their online portal. For the state high-volume breeder license, you must apply through the Ohio Department of Agriculture's Commercial Dog Breeding Program, which also conducts inspections. You will generally need to provide proof of current rabies vaccination and pay the required fee when licensing individual dogs. Because the exact process and documents vary by county, contact your County Auditor's office directly and, for commercial breeding, the Ohio Department of Agriculture.

Individual dog license fees are set locally and vary by county (for example, Lake County lists an adult dog license at $20.00 per dog, and Warren County lists a 2026 application fee of $15.00). County kennel license fees also vary, and state law sets a base kennel registration fee of $10 a year (with up to five tags), which counties may raise by resolution, and a penalty equal to the fee applies if it is not paid by January 31 (R.C. 955.04, 955.14); confirm your county's amount with the County Auditor. The state high volume breeder license fee is set by R.C. 956.07: $150 for selling 40 to 60 puppies a year to the public, $250 for 61 to 150, $350 for 151 to 250, $500 for 251 to 350, and $750 for 351 or more ($150 if licensed only because of sales to brokers or pet stores or the number of puppies kept). High volume breeders must also carry insurance or a surety bond of $5,000 to $50,000 depending on the number of adult dogs (R.C. 956.03). Late fees apply if dog licenses are not renewed on time (for example, a $20.00 per dog late fee in Lake County).

High-volume commercial breeders are inspected by the Ohio Department of Agriculture, and state law allows inspections during regular business hours without advance notice (R.C. 956.10). 956.10). State regulations require high-volume breeders to monitor dogs and puppies for evidence of disease, injury, or improper or inadequate care. The Ohio Department of Agriculture runs a Commercial Dog Breeding Program with inspectors who check that individuals and businesses meet standard-of-care requirements. Senate Bill 232, introduced in July 2025 to revise the high volume breeder law including inspections, has been in the Senate Agriculture and Natural Resources Committee since October 2025 and is not law.

High-volume breeders regulated by the Ohio Department of Agriculture must follow standard-of-care rules, which include monitoring dogs and puppies for disease, injury, or inadequate care. High volume breeders must keep a record of veterinary care for each dog for three years after the care is provided (R.C. 956.03); other record rules are set in Ohio Department of Agriculture rules. Breeders should consult the Ohio Department of Agriculture's Commercial Dog Breeding Program and Ohio Revised Code Chapter 956 for the full record-keeping requirements. County kennel and dog registration records are handled through the County Auditor.

Failing to register a kennel is a strict liability offense with a fine of $25 to $100 for a first offense and $75 to $250 plus up to 30 days in jail for later offenses (R.C. 955.04, as recodified by House Bill 247, effective March 20, 2026). For commercial breeders, the Ohio Department of Agriculture can take enforcement action, including moving to revoke a high-volume breeder's license after inspectors find serious problems, as shown in a recent case involving a Loudonville breeder. Breeders who fail inspections or violate standard-of-care rules risk losing their state license. The Ohio Department of Agriculture can assess civil penalties against high volume breeders of up to $2,500 for a first violation, $5,000 for a second, and $10,000 for a third or later violation, with each day counted as a separate violation (R.C. 956.13).
