Dog Licensing Overview

Butler County licenses over 35,000 dogs per year.  Not only is the license required by law, it ensures your dog a free ride home.  When the deputy dog wardens find a licensed dog running loose, they can look up the information and make sure your dog is returned to you safe and sound.

State law changed effective Dec. 1, 2013 allowing for the purchase of 1-year, 3-year or permanent dog tags. Those wishing to purchase a 3-year tag ($42) or a permanent tag ($140) should do so directly through the Auditor's Office. Only 1-year tags may be purchased Online or through our agents.

Kennel License Information

Requirements for a Kennel under the Butler County, Ohio Rural Zoning Resolution, which applies to the following six townships - Hanover, Lemon, Madison, Milford, Oxford, Ross, are:

  • Shall have direct access to a major arterial or to a collector street.
  • The site shall not contain fewer than ten (10) acres.
  • Any building for this use shall be located not less than 300 feet from any property line.
  • Landscaping plan for the external use of the kennel to effectively screen such use shall be submitted to the board of zoning appeals for approval

Residents of these six townships applying for the first time for a kennel license must present a letter from their local zoning board confirming the above requirements have been met.

Other townships and municipalities may have different requirements. The Auditor's Office requires a letter confirming that the location of the kennel meets local zoning regulations before a kennel license will be issued for the first time.

Cost of a kennel license is $70.00 per year as long as the license is renewed by January 31, this includes 5 dog licenses. After January 31 there is a $70.00 penalty for all renewals. Up to 5 additional licenses may be purchased for $1.00 each.

Dangerous Dog Registration 

Per state statute, the County Auditor is required to issue a dangerous dog registration certificate and a dangerous dog tag to a person who is the owner of a dangerous dog, who is 18 years of age or older, and who provides a fee of $50 and certain specified information. The owner of a dog who is issued a dangerous dog registration certificate is required to renew the dog’s registration certificate annually for the same fee and in the same manner as the initial certificate was obtained.
