Summary
Unincorporated Santa Clara County doesn't mandate spaying every pet, but caps each household at one unspayed female dog and one unspayed female cat before a kennel permit is required.
In addition, of the animals legally permitted on the property, not more than one female dog may be unspayed. A female dog shall be rebuttably presumed to be unspayed unless the owner/guardian provides evidence of spaying. Written certification from a licensed veterinarian that an animal cannot be spayed for health reasons or is incapable of breeding shall be deemed a satisfactory substitution for a certificate showing that an animal is spayed.(b)A maximum of three dogs shall be allowed on parcels of five acres or more, unless a permit for a private kennel, commercial kennel, animal menagerie, or animal shelter is obtained by the owner/guardian of the animals.(c)These provisions shall not apply to premises maintained by a veterinarian licensed by the State for the practice of veterinary medicine. (Ord. No. NS-300.745, § 1, 5-2-06)
Sec. B31-33. - Vaccination of dogs. The owner/guardian of a dog over four months of age shall cause such dog to be vaccinated with an anti-rabies vaccine approved by the State Department of Public Health. Revaccination shall be made at such intervals of time as may be prescribed by the State Department of Public Health. Compliance with the provisions of this section shall be a condition to the issuance or renewal of dog licenses. Violation of this section shall be punishable as a misdemeanor.
(Ord. No. NS-300.745, § 1, 5-2-06)
Sec. B31-34. - License required.

Full Breakdown
The County has no blanket law forcing every pet to be spayed or neutered. Instead, within the household dog and cat limits, no more than one female dog (Section B31-32) and no more than one female cat (Section B31-51) may go unspayed; a female is rebuttably presumed unspayed unless the owner produces proof, though a vet's written statement that the animal can't be spayed for health reasons or can't breed satisfies the rule instead. Reduced license fees under Sections B31-35 and B31-57 give an added financial incentive to spay or neuter.
Violations & Fines
Exceeding the unspayed-female cap without a kennel permit can trigger impoundment proceedings under Section B31-20.
