Summary

Peoria does not require every pet to be sterilized, but it does require it before a stray dog or cat leaves the pound with a new owner. Section 16-31(c) conditions any pound sale on the animal already being spayed or neutered, or on the buyer signing a sterilization agreement and posting a deposit with the pound.

(c) Prior to release of a stray dog or cat from the pound for purchase by any person: (1) The dog or cat shall be surgically spayed or neutered; or (2) The purchasing party shall sign an agreement with the pound to have the dog or cat spayed or neutered within thirty days after purchase or before the dog or cat is sexually mature and deposit with the pound the amount determined by the pound to be sufficient to assure sterilization. Upon presentation of a statement by a veterinarian that the dog or cat has been spayed or neutered, the deposit shall be refunded.

Full Breakdown

Chapter 16's pound provisions run from Sec. 16-31(a) through (f). A stray dog must be impounded, and any impounded dog or cat is held at the pound for a minimum of 72 hours before the owner can reclaim it, under Sec. 16-31(a)-(b). If nobody reclaims the animal and it is instead sold to a new owner, Sec. 16-31(c) requires one of two things first: the dog or cat must already be surgically spayed or neutered, or the buyer must sign an agreement with the pound to have it done within thirty days after purchase or before the dog or cat is sexually mature, backed by a deposit the pound sets to assure sterilization.

The deposit is refunded once the buyer produces a veterinarian's statement confirming the surgery was done. S. Sec. 11-1022(C), the state statute governing pound sterilization funds. There is a narrow carve-out in Sec. 16-31(e): if the dog or cat is transferred for medical research instead of adopted, no license, vaccination, or sterilization condition applies. Section 16-31(e) also lets the enforcement agent destroy an impounded dog or cat that is sick or injured, or is needed to prevent disease spread, without waiting out the sterilization or reclaim process.

Violations & Fines

Selling or releasing a pound dog or cat without meeting the Sec. 16-31(c) sterilization condition is enforced the same as any other Chapter 16 violation: a class one misdemeanor or a civil penalty up to $2,500 under Sec. 16-35(a), and the pound can withhold release of the animal until the spay/neuter proof or deposit is in hand.

Frequently Asked Questions

Do I have to spay or neuter a dog I adopt from the Peoria pound?
Yes, unless it is already sterilized. Section 16-31(c) requires it before purchase, or requires you to sign an agreement to have it done within 30 days (or before sexual maturity) and post a deposit with the pound.
Do I get my sterilization deposit back?
Yes. Section 16-31(c) refunds the deposit once you present a veterinarian's statement showing the dog or cat has been spayed or neutered.
Does every pet owner in Peoria have to spay or neuter their animal?
No. Chapter 16 only mandates sterilization as a condition of buying an animal released from the City pound under Sec. 16-31(c); it does not impose a general spay-neuter mandate on all pet owners.
