Full Breakdown
Once the Olathe Municipal Court formally declares a dog dangerous under § 8.10.110(A), § 8.10.110(C)(6) requires the owner or harborer to have it spayed or neutered as one of the mandatory compliance conditions, alongside confinement, warning signs, microchip identification, an annual dangerous-dog license, behavior-modification training, and $100,000 liability insurance. The Municipal Court sets a compliance hearing within forty days of the dangerous determination; if full compliance, including the spay/neuter requirement, isn't verified there, the dog is impounded, and if still unverified after a further 30-day window, it is euthanized or the owner must remove it from Olathe. There is no general spay/neuter mandate for ordinary pet dogs or cats in the city.
Violations & Fines
Failure to spay or neuter a court-declared dangerous dog, along with any other unmet § 8.10.110(C) condition, results in impoundment at the 40-day compliance hearing; if still unverified after 30 more days, the dog is euthanized or must be removed from Olathe.
