Norwalk, CT Animal Ordinances: Mandatory Spay/Neuter (2026)

Norwalk's Code has no blanket spay-or-neuter law for ordinary pets; the requirement appears only inside the vicious dog framework in Chapter 15, Article II. When the Board of Police Commissioners declares a dog vicious under § 15-14 and chooses under § 15-15B to let the owner keep it rather than have it destroyed, the owner must accept eight conditions listed in that subsection, one of which, § 15-15B(5), obligates the owner to obtain a certificate from a licensed veterinarian confirming the dog has been spayed or neutered and to pay for the procedure.

The Dog Warden holds the impounded dog and, per § 15-15C, will not release it back to the owner until all conditions in § 15-15B(1) through (6), including the spay/neuter certificate, tattoo, insurance, licensing, signage, and secure enclosure, are satisfied to the Dog Warden's approval. Section 15-18B makes the Dog Warden responsible for verifying continued compliance and empowers seizure and impoundment of any vicious dog whose owner falls out of compliance with § 15-15B, adding a $99-per-day fine for each day of violation on top of the seizure and impoundment costs.

If the owner instead refuses any condition, or the Board orders destruction outright under § 15-15A, the spay/neuter step never becomes relevant because the dog is destroyed after the fourteen-day appeal period instead.
