Summary

Rock Island County does not require spay/neuter for pets generally, but a dog declared dangerous must be spayed or neutered within 14 days at the owner's expense, a vicious dog within ten days, and the county waives an impound redemption fine for any first-time impounded pet fixed within 14 days.

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

If deemed dangerous, the Administrator, or his or her designee, or the Director shall order: (a) The dog's owner to pay a $50 public safety fine to be deposited into the Pet Population Control Fund; (b) The dog to be spayed or neutered within 14 days at the owner's expense and micro chipped, if not already;

Full Breakdown

County Code Sec. 050(C)(1)(b) orders that once a dog is deemed dangerous by the Administrator or Director following the investigation and hearing process in Sec. 050(A)-(B), the Administrator must order the dog spayed or neutered within 14 days at the owner's expense and microchipped if it is not chipped already. Sec. 051(D) imposes a similar but shorter mandate for a dog a Circuit Court finds to be vicious under the clear-and-convincing-evidence standard in Sec. 051(A)-(C): the dog must be spayed or neutered within ten days of the finding, again at the owner's cost, on top of a $100 public safety fine and a requirement that the dog live in a secure enclosure.

Outside the dangerous/vicious dog track, the county also uses spay/neuter as a financial incentive rather than a blanket mandate: Sec. 008(G) charges a $25 public safety fine to redeem any impounded dog or cat, but waives that fine entirely if it is the animal's first impoundment and the owner has it spayed or neutered within 14 days. Sec. 070 layers on a related duty for intact animals: an owner of a female dog or cat in heat must confine her to prevent unplanned breeding, and the owner of a male dog or cat that gets loose and mates with a properly confined female becomes financially responsible for a mismating remedy and the cost of caring for or placing the resulting litter, which functions as a further financial push toward sterilization for owners who do not want that liability.

Violations & Fines

An owner who does not have a dangerous dog spayed or neutered within the 14-day window, or a vicious dog within ten days, is out of compliance with the Administrator's or court's order and the Administrator can impound the dog under Sec. 91.050(C)(3); for a vicious dog, non-compliance triggers impoundment plus a $500 fine under Sec. 91.051(E), and the judge may order euthanasia if the owner does not appeal within 15 working days.

Frequently Asked Questions

Does Rock Island County require all dogs and cats to be spayed or neutered?
No. There is no blanket spay/neuter mandate for owned pets. The requirement is triggered specifically when a dog is declared dangerous under Sec. 91.050 or found vicious under Sec. 91.051, or as a fee-waiver incentive for a first-time impounded animal under Sec. 91.008(G).
How fast must a dangerous dog be fixed?
Sec. 91.050(C)(1)(b) requires the dog to be spayed or neutered within 14 days of the dangerous-dog determination, at the owner's own expense, along with microchipping if the dog is not already chipped.
What if I don't get my impounded pet spayed or neutered?
For a first-time impoundment, Sec. 91.008(G) waives the $25 public safety redemption fine only if the pet is spayed or neutered within 14 days; skip that window and the full fine applies before the animal is released.
