Purchasing a license tag and attaching it to your pet's collar is one of the most important things you can do as a responsible pet owner. Displaying a current Contra Costa County license tag on your pet's collar makes it easy for animal control officers and shelter employees to quickly locate a lost pet's owner information. It could be your pet's ticket home!
