Full Breakdown
Sioux City Municipal Code § 7.03.070(5), in the Woodbury County seat's animal-control chapter, requires that once an animal is classified 'high risk' (a dangerous-animal finding under § 7.01.010(13)), its owner must have it spayed or neutered by a veterinarian at the owner's own expense, and keep it microchipped with current data. The owner has ten days from the high-risk designation to comply with this and the chapter's other confinement and signage duties.

Failure to sterilize and microchip within the 10-day compliance window supports impoundment under § 7.03.075 and municipal-infraction penalties under § 1.04.100.
