Summary
Tucson doesn't require every pet to be fixed, but once a magistrate finds an animal vicious or destructive under Section 4-7, the court can order it spayed or neutered by a licensed veterinarian at the owner's expense as a condition of keeping the animal.
Sec. 4-7(3). Penalty... In addition, unless the animal has been previously forfeited or destroyed, upon a finding of guilt, a magistrate or special magistrate shall declare an animal vicious or destructive and shall order one (1) or more of the following: (a) That the animal shall be spayed or neutered by a licensed veterinarian at the owner's expense and that the owner of the animal shall comply with the provisions of sections 4-13(e), (f) and (g); or (b) That the animal be banished from the city limits after first being spayed or neutered, microchipped and tattooed...; or (c) That the animal be humanely destroyed.

Full Breakdown
Section 4-7(3) sets the penalty structure after a magistrate finds an owner guilty of keeping a vicious or destructive animal. Beyond the fine, the magistrate must declare the animal vicious or destructive and order one or more remedies, the first of which, Section 4-7(3)(a), is that the animal be spayed or neutered by a licensed veterinarian at the owner's expense, with the owner also required to comply with the confinement, muzzling, signage and insurance conditions of Section 4-13(e), (f) and (g). The alternative remedies are banishment from the city after spay/neuter, microchipping and tattooing, or humane destruction of the animal, so spay/neuter is the least severe of the three court-ordered outcomes.
The same spay/neuter duty resurfaces independently in Section 4-13(e): once an animal is administratively declared dangerous (a lower bar than a court finding of vicious/destructive), the city enforcement agent issues an order of compliance giving the owner 30 days to have a licensed veterinarian spay or neuter the animal, with written veterinary certification required afterward. Restitution to the victim is also ordered separately and doesn't preclude a civil suit.
Violations & Fines
Any violation under Section 4-7 carries a fine of $200 to $2,500, with no judicial discretion to suspend the minimum, plus up to six months in jail and three years' probation. Failing to comply with the magistrate's spay/neuter order is itself a separate misdemeanor offense for each day of noncompliance under Section 4-7(2)(d). Failing to complete a Section 4-13(e) administrative spay/neuter order can lead to seizure of the animal under the inspection and enforcement provisions of Section 4-13(f).
