Pet Licensing Requirements

All dogs and cats 4 months of age or older must have a current rabies vaccination and a County pet license. A pet license is required even if the dog or cat is always on the owner’s property, is always indoors, or lives on a farm.  The rabies tag provided by your veterinarian is NOT a County license — the license must be purchased separately.

Why Licensing Your Pet is ImportantYorkie with collar and tags

It Can Save Your Pet's Life

  • When local residents find stray pets, they can call Animal Services. If your pet gets lost, a license tag on your pet’s collar is the fastest way to find you when your pet is found. Even if your pet is microchipped, a license tag is immediately visible and doesn’t require a scanning device to read it, like a microchip does. With the license numbers, our staff can give the pet finder your contact information. In that case, your pet will never even have to come to the Animal Services and Adoption Center.
  • We will contact you right away if a good Samaritan brings your pet to the Center and if your pet is wearing his pet license tag. Last year we reunited 1,025 lost pets with their owners.
  • When an Animal Services Officer picks up a lost pet in the field, the officer can quickly identify the owner and may be able to bring your lost pet right back to your home. 
  • If your pet is found injured and wearing its license, Animal Services Officers will attempt to obtain emergency medical attention for it and contact you with the details.

It Supports the Community

Pet licensing fees help support the County’s Animal Services program, and that program is good for people and pets. We provide a safe shelter for homeless, unwanted, abused and neglected pets, provide education and outreach in the community, investigate cases of animal cruelty and neglect, and protect neighborhoods like yours from dangerous dogs.

It Promotes a Healthy and Safe Pet Population

Pet licensing protects your pet and the community from the deadly rabies virus. Licensing lets people know that your pet is up to date on its rabies vaccinations and  provides visual proof that an animal has been vaccinated against rabies.Your pet cannot be licensed unless it is properly vaccinated.

It Shows Responsible Pet Ownership

Your pet’s license shows that you are a responsible pet caregiver. When you walk your dog or let your dog run in designated areas, people will notice the license on your dog’s collar and know that you really care about your dog’s welfare.

Plus...It’s the law. In most states, it’s mandatory that pet owners have their pets licensed. If you get caught without a pet license, which can and does happen, you will be hit with a hefty fine.
