Portage County, WI Animal Ordinances: Mandatory Spay/Neuter (2026)

Section 4.9.16, 'Animal Control Agency,' lets Portage County contract with an outside organization to run a county animal shelter, impound strays, and administer rabies-vaccination programs under § 4.9.16(1). Subsection (2) then narrows the county's spay-and-neuter reach to that shelter pipeline: dogs and cats adopted from the county designated pound or animal shelter must be spayed or neutered in accordance with the facility's own policies. Nothing in Chapter 4.9 extends a spay-or-neuter mandate to dogs and cats already owned in the towns, only to those coming out of the county pound or contracted shelter.

The rule works together with § 4.9.4's dog-license fee structure, which charges $12.00 for a license on a neutered male or spayed female dog against $22.00 for an unaltered dog, giving owners a financial incentive that stops short of a legal requirement. Because the actual spay/neuter standard is set by the facility's policy rather than the county ordinance itself, the specific age, cost or exception rules an adopter faces depend on whichever shelter or humane society Portage County has under contract at the time, and that contract can change; the humane officer appointed under Wis. Stat. § 173.03 and § 4.9.16(1) oversees compliance on the county's behalf.
