Summary
Dearborn requires owners of dogs formally declared "dangerous" to have them spayed or neutered and microchipped within 14 days, at the owner's own expense, under Code of Ordinances § 4-27A(c).
If deemed dangerous, the owner shall: (1) Have the dog spayed or neutered within 14 days at the owner's expense and microchipped, if not already; and (2) Have an evaluation of the dog by a certified applied behaviorist, a board certified veterinary behaviorist, or other recognized expert in the field and completion of training or other treatment as deemed appropriate by the expert.

Full Breakdown
This is not a citywide spay/neuter mandate: it applies only after the Dearborn Animal Shelter manager formally determines a dog is "dangerous" under Code of Ordinances § 4-27A. Once that determination is made, § 4-27A(c) requires the owner to have the dog spayed or neutered and microchipped within 14 days, entirely at the owner's expense, and to obtain a behavioral evaluation from a certified applied behaviorist or veterinary behaviorist, completing any training the expert orders. Dearborn separately gives ordinary dog owners a financial incentive, not a mandate, toward sterilization: a reduced license fee, and a fee-free lifetime license, for dogs proven sterilized and microchipped.
Violations & Fines
Noncompliance can lead to impoundment of the dog under § 4-27A(d). A dog later found vicious after evaluation faces licensing, $100,000 insurance, and confinement requirements under § 4-27B.
