Required Paperwork

1. A current rabies vaccination certificate is required if the rabies vaccination on file has expired. Please check your certificate for correct address and pet information.
2. Proof of spay/neuter, such as a signed statement from a veterinarian or an invoice for services is required if the pet has been altered since the last licensing period and you are applying for the lower spayed/neutered license fee.
3. Proof of age is required to receive the reduced-fee license for senior citizens age 60 and over with a spayed or neutered pet.
4. If licensing an unaltered exempt dog for the first time, please submit proof of the dog's registration with the AKC or UKC. Actively working cattle and hunting dogs will need to be licensed the first time with Animal Services, but may be renewed through the mail or online.

Your paperwork will not be returned to you, so please retain a copy of your documents for your records.

*All dogs in Lake County are required to be spayed or neutered. However, registered purebreds and actively working cattle dogs or hunting dogs may apply for an exemption and reduced license fee. To license a purebred, a copy of the dog's registration with the AKC or UKC must be included with the initial license application. An exemption for a working cattle or hunting dog requires an inspection and approval from the Animal Services Department for the initial license.

**Please contact Animal Services for Service Dog licenses.

The cost for licensing unaltered or fertile pets is higher than for licensing spayed or neutered pets in order to promote sterilization and to reduce pet overpopulation and starvation.
