All dogs in Orange County over the age of four months are required by law to be licensed and vaccinated against rabies. Residents owning or having custody of any dog must license the dog within 15 days of acquisition or within 15 days after the license becomes due. Residents must provide proof of a California approved rabies vaccination to obtain a license (OCCO 4-1-70). Cat licensing is optional and available through OC Animal Care. Licensing your dog provides necessary information to support investigations of cruelty, neglect, abandonment and dog bites. Licensing also indicates ownership of a dog. If your dog is found, OC Animal Care will call and send you a letter. For more information on licensing, please visit OCAC’s page or call (714) 935-6848.
