House Bill 404 (COVID-19 Government Responses)

To Whom It May Concern,

Please be advised that due to House Bill 404 (COVID-19 Government Responses), there has been an extension of when dog tag registration, renewal and penalties shall take effect.
Dog tags, new purchases and renewals, have until the end of the day, July 1, 2021 to buy their tags without penalty. Effective July 2, 2021, any purchase or renewal of a dog tag will be subject to the late fee.
Thank you for your support of the Clark County Auditor’s office and for selling dog tags to register dogs throughout the county. Remember, without a tag, every dog is a stray.

Thanks again,
Auditor John Federer
