Summary
San Jose has no citywide law requiring pet dogs or cats to be spayed or neutered. The mandate is narrow: once the city formally designates a dog "potentially dangerous," § 7.30.910(B) requires that dog be spayed or neutered as a condition of keeping it.
7.30.910 - Potentially dangerous dog maintenance requirement. The administrator may impose any or all of the following requirements upon the maintenance of a potentially dangerous dog:
A.A potentially dangerous dog must be muzzled and leashed, as specified under Section 7.30.950, when it is on any public street or in any other public place, or upon any private place or property or common area of any planned development, cluster, townhouse, or condominium project unless the dog owner/guardian or person with a right to control the dog has obtained the consent of the owner/guardian or person in control of the private place or property or common area of the planned development, cluster, townhouse, or condominium project.B.A potentially dangerous dog must be spayed or neutered.C.A potentially dangerous dog must have a microchip implant for identification purposes.D.A potentially dangerous dog is subject to special dog permit tag requirements under Section 7.30.540.E.The dog owner/guardian or person with a right to control the dog must seek pre-approval from the administrator for a dog obedience class and attend the dog obedience class with the dog that exhibited the behavior specified in Section 7.10.180.

Full Breakdown
Chapter 7.30 governs dogs found potentially dangerous, dangerous, or vicious after a behavior-based designation under § 7.10.180. Once a dog carries that designation, § 7.30.900 makes it unlawful to possess or maintain the dog except as § 7.30.910 requires, and subsection B is unconditional: "A potentially dangerous dog must be spayed or neutered." The same section can also require muzzling and leashing in public, a microchip implant, a special dog permit tag, and administrator-approved obedience training. For the general pet population, San Jose only encourages alteration: § 7.20.540(C) gives spayed/neutered dogs and cats a reduced license fee, and § 7.40.020(C) presumes an unaltered female dog or cat unless the owner shows proof of spaying, neutering, or a veterinary inability-to-alter certificate.
Violations & Fines
Possessing or maintaining a potentially dangerous, dangerous, or vicious dog in violation of Part 9 is unlawful under § 7.30.900. Noncompliance can lead to special dog permit denial or revocation, a hearing officer's seizure order, and disposal of the dog under §§ 7.30.700-.710.
