Florissant, MO Animal Ordinances: Mandatory Spay/Neuter (2026)

Section 205.395(B) of the Florissant Code makes it unlawful to own, keep or harbor a pit bull that the owner knew or should have known was unspayed or unneutered, unless one of six exceptions applies: the dog is under eight weeks old; a veterinarian certifies spaying or neutering would risk serious harm or death, with documentation filed with the Director of Public Works and Health within thirty days; the dog has been in the city less than thirty days; the owner has applied for or holds a breeding and transfer permit; the breed determination is under appeal; or the dog is a registered AKC or UKC show dog with papers filed within thirty days.

A first violation is punishable by a fine of up to $500, and the Director impounds the dog. To get the dog back, the owner must either let the Director arrange a veterinarian to spay or neuter it after paying a $100 deposit plus the actual procedure cost, pay the Director $60 to deliver the dog to a veterinarian of the owner's choosing, or sign an affidavit promising to have the procedure done within two weeks and provide proof afterward. If that affidavit deadline is missed, the Director may impound the dog again and charge a second violation. The Director may waive part or all of the fees if payment would cause the owner extreme financial hardship. A second violation is punishable by up to six months in jail, a fine of up to $1,000, or both, and the Director impounds the dog and disposes of it under Chapter 205.
