San Jose FAQ
Who can keep an intact dog or cat in San Jose?
Licensed breeders, registered show or working animals, guide and service dogs, and pets with a veterinarian's medical exemption can stay intact, but each owner must hold an annual intact-animal permit issued by Animal Care and Services.
How much more does an unaltered license cost?
Significantly more than an altered license. Fee schedules are set by Animal Care and Services and updated periodically. Low-cost spay and neuter clinics are offered to reduce barriers to compliance.
Sunnyvale FAQ
Are all dogs in Santa Clara County required to be sterilized?
Not countywide. Unincorporated SCC mandates sterilization only on shelter release. San Jose, Sunnyvale, and several other cities extend the rule to all owned dogs and cats over four months, with intact-permit options.
Are there exceptions to the shelter sterilization rule?
Yes. California Food & Ag Code §30503 allows medical-waiver exceptions documented by a veterinarian. Some show or breeding animals can also qualify, though SCC Animal Services applies the rule strictly at adoption.
