Why should I license my dog?

First and foremost it is the law.  It is also a great identification tag to get your lost dog back to you.  There are many cases where a dog gets loose from its owner, and is able to be reunited because of the license.  No dog shall be harbored, kept, or owned without displaying a valid registration tag.  (The law applies regardless of whether the dog is kept inside or outside.)

Does my dog need a license?

Yes.  All dogs older than three months of age must be licensed.

How often does the license have to be renewed?

Dog licenses must be renewed annually between December 1 and January 31, unless you purchase a three-year or permanent dog license (this is different than a three-year rabies tag).

How much does a license cost?

The base fee for a dog license is $18.00 annually, with the exceptions listed below.  After July 1, some fees may be prorated. 

How much does an annual, three-year, or permanent license cost?

For an annual tag, the cost is $18.00.  For a three-year tag, the price is three times the annual fee.  A permanent license is ten times the annual fee.  If you are late purchasing the license, the penalty is the annual fee only.

How can I avoid late fees?

The penalty can be avoided if you purchase the dog license immediately upon acquiring the dog.  After the renewal period of December 1 through January 31, a penalty will be assessed for all dogs licensed that are older than three months of age and have been owned for more than 30 days.

When can a license deadline be extended?

When the January 31 license renewal deadline falls on a Saturday or a Sunday, the deadline is extended to the next business day.  Also, the county commissioners may extend the deadline by county resolution.

How do I replace a lost license?

If you or your pet loses a license, you can request a duplicate tag for $5.00.  Please send us a check or money order with a letter that includes your name, address, and license number (if known) so we can send a replacement tag. 

How do I transfer a license to a new owner?

The ownership of a current dog license can be transferred to another owner for just $5.00.  The current owner on file, or executor of the current owner’s estate, must sign the transfer form.  It is also advisable for the new owner to sign the form. Licenses are NOT transferrable between dogs.

Where can I find the laws that apply to dog licensing?

The laws governing dog licensing in the State of Ohio can be found in the Ohio Revised Code (ORC), sections 955 and 956.

How do I notify your office that I have moved out of the county?

You may call our office, email our office at or send us a letter informing us of the move.  We will mark the record(s) accordingly.  Please note that most counties in Ohio will recognize the tag until it expires.  When that license expires (if it is not a permanent tag), you will need to contact the auditor of the county to which you have moved.

If I move here from another county in Ohio, is that county's current license still valid?

Yes.  We will honor the license until it is expired.  You will need to provide a change of address to the auditor of the county from which you have moved.  When that license expires, you will need to contact our office.

If I move here from another state, is that state's license valid?

No.  You are required to purchase a license immediately upon arrival in the State of Ohio.  If you wait more than 30 days, the county auditor is required to charge a penalty equal to the fee.

How do I obtain an assistance dog license?

Complete the standard dog license application and send it with proof of training from a nonprofit special agency as required by the Ohio Revised Code (955.011).  This registration is free and permanent.
