Summary

A stray dog impounded three or more times in 12 months in Honolulu must be spayed or neutered by animal control before its owner can redeem it.

These county ordinances apply to unincorporated areas of Honolulu County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

In addition to the fees specified in subsection (a), an unsterilized dog, while being a stray, that is impounded by the animal control contractor at least three times within a 12 month period, must be spayed or neutered by the animal control contractor before the owner may redeem the dog, unless a licensed veterinarian certifies that the medical condition of the dog disqualifies the dog from being spayed or neutered.

(c)   In addition to the fees specified in subsection (a), a sterilized dog that is impounded by the animal control contractor for being a stray at least three times within a 12 month period, may be redeemed by its owner upon payment of a $30 fee.

(d)   If an impounded dog is redeemed by its owner within 24 hours of physical possession of the dog by the animal control contractor, the animal control contractor will waive any impoundment fees.

(e)   A special officer of the animal control contractor shall be authorized to enforce this article if deputized by the chief of police to do so.

(f)   The animal control contractor shall spay or neuter any impounded dog before the dog is adopted, unless a licensed veterinarian certifies that the medical condition of the dog disqualifies the dog from being spayed or neutered, or that being spayed or neutered would otherwise be detrimental to the health of the dog (Sec. 13-23.3, R.O. 1978 (1983 Ed.)) (1990 Code, Ch. 7, Art. 4, § 7-4.3) (Am. Ords. 00-68, 07-33, 20-1)

Full Breakdown

When the city's animal control contractor impounds an unsterilized dog as a stray at least three times within a 12-month period, the contractor must spay or neuter the dog before the owner may redeem it, unless a licensed veterinarian certifies the dog's medical condition disqualifies it from the procedure. This is on top of standard impoundment fees.

Violations & Fines

An owner cannot redeem a third-time stray within 12 months until the dog is sterilized or a veterinarian certifies a medical exemption; the dog remains impounded until then.
