Pet Licensing in Hamilton County
Last Updated: August 2026
Hamilton County does not currently require a general county dog license or dog tax. However, dog and cat owners still need to follow county rules for rabies vaccination, permanent identification and other animal requirements.
Cities and towns within Hamilton County may also have their own animal ordinances.
Quick Answer
There is no general Hamilton County dog license or dog tax.
Indiana eliminated the former dog tax in 2006 and allowed counties to adopt their own County Option Dog Tax. Hamilton County did not adopt one.
However, Hamilton County requires dogs and cats age 3 months or older to have permanent identification and current rabies vaccination.

Permanent Pet Identification Is Required
Hamilton County requires dogs and cats 3 months of age or older to have permanent identification.
This can be:
- A registered microchip that can be read by a standard scanner, or
- A permanent tag on a durable collar showing the owner’s current name and telephone number.
A microchip is therefore not specifically required, as long as the pet has an acceptable permanent identification tag.
Rabies Vaccination Requirements
Dogs, cats and ferrets age 3 months or older must be vaccinated against rabies and kept current on required vaccinations.
Keep your pet’s vaccination records in a safe place and make sure required tags and identification remain current.

Why Identification Matters
Permanent identification helps Animal Control, veterinarians and the Humane Society for Hamilton County identify an owner when a pet gets lost.
If your pet is microchipped, make sure the registration includes your current phone number and contact information.
