In the City of Rancho Cucamonga and the State of California, all dogs over four (4) months of age are required to be licensed and vaccinated against rabies. Cat licenses, while voluntary, are available and highly recommended. The Rancho Cucamonga Animal Center has partnered with DocuPet to provide an enhanced pet licensing experience for residents. Your pet's license now includes DocuPet's free HomeSafeTM 24/7 lost pet service and designer license tags with personalization options. Additionally, 20% of every product sale (designer tags, collars and leashes) is donated to Rancho Cucamonga Animal Center through DocuPet's Safe & Happy Fund.
