Yep. It’s the law, falling under Yolo County Ordinance 6-1.406.
The reason is two-fold. First, licensing increases the likelihood that your pet will be reunited with you if he or she becomes lost. Second, licensing your dog also helps prevent against rabies outbreaks by requiring all dogs to be vaccinated for rabies.
Also please remember to keep your dog on a leash. West Sacramento’s leash law (Municipal Code Section 6.16.020, Dogs on leashes) states, “No owner shall permit his or her dog to be in any residential, commercial or industrial area, other than on private property where the dog is maintained by or on behalf of its owner, unless the dog is restrained by a leash not exceeding eight feet in length. The only exceptions are Police K-9s, dogs assisting those engaged in hunting with a license, and dog training or exhibitions conducted with the permission of the property owner.
Further, dog owners are required by law to clean up after their pets (Municipal Code Section 6.16.220).
Please be a responsible dog owner! Thanks for your cooperation.
