Summary

Fresno County requires every dog and cat over four months old to be spayed or neutered unless the owner buys an unaltered dog license or a breeding permit. County Code Section 9.05.030 sets the mandate, and Section 9.05.060 backs it with a $1,000 civil penalty per animal for noncompliance.

City-specific rules exist: Fresno, and Clovis have their own mandatory spay/neuter rules that differ from Fresno County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

A. No person shall own a dog or cat that is over the age of four (4) months in the County that is not spayed or neutered unless, in the case of dogs, the owner has applied for and received an unaltered dog license or, in the case of dogs and cats, the owner has applied for and received a breeding permit pursuant to this Chapter. B. No owner of an unaltered female dog or cat shall allow the dog or cat to breed without first obtaining a breeding permit pursuant to this Chapter. C.

Full Breakdown

Fresno County Code Section 9.05.030, part of the Breeding, Transfer and Sale of Dogs and Cats Ordinance adopted by Ordinance No. 25-016 on July 8, 2025, provides that no person shall own a dog or cat over the age of four months in the County that is not spayed or neutered unless, for dogs, the owner has applied for and received an unaltered dog license, or, for dogs and cats, the owner has applied for and received a breeding permit. A separate clause bars letting an unaltered female dog or cat breed at all without first obtaining a breeding permit.

The Board of Supervisors' stated purpose in Section 9.05.010 is controlling a serious pet overpopulation problem that has driven euthanasia of healthy animals and escalating shelter costs in the unincorporated county. Section 9.05.040 backs the mandate with real screening: a breeding permit costs a nonrefundable $50 application fee plus an annual permit fee set in the county's Master Fee Schedule, requires a Sheriff's background check, is barred to anyone under eighteen or anyone whose dog has been declared dangerous, and limits breeding to American Kennel Club-recognized breeds, capping a household at three breeding permits before it must instead get a Section 9.04.050 kennel license. Section 9.05.060 enforces the whole chapter: a first violation gives the owner thirty days to get the missing license after a notice, after which a $1,000 civil penalty per animal applies, and failing to resolve the violation and pay within another thirty days becomes a misdemeanor punishable by up to six months in jail.

Violations & Fines

Owning an unaltered dog or cat over four months without an unaltered dog license or breeding permit violates Section 9.05.030. Under Section 9.05.060, the county first gives the owner thirty days from a notice of violation to obtain the license; missing that window brings a $1,000 civil penalty per animal, and failing to pay and correct the violation within another thirty days becomes a misdemeanor carrying up to six months in county jail. A second violation within a year adds another $1,000 penalty per animal.

Frequently Asked Questions

Does Fresno County require pets to be spayed or neutered?
Yes. Section 9.05.030 makes it unlawful to own a dog or cat over four months old in the county that is not spayed or neutered, unless the owner holds an unaltered dog license (for dogs) or a breeding permit (for dogs and cats). It applies countywide in the unincorporated area under the Breeding, Transfer and Sale of Dogs and Cats Ordinance.
What happens if I don't spay or neuter my pet and don't get a license?
Section 9.05.060 gives you thirty days to obtain the required license or permit after the county issues a notice of violation. Miss that window and a $1,000 civil penalty per animal applies. If you still don't pay and correct the violation within another thirty days, it becomes a misdemeanor punishable by up to six months in county jail.
How do I keep my dog or cat unaltered legally?
Dog owners can apply for an unaltered dog license; anyone wanting to breed a dog or cat needs a separate breeding permit under Section 9.05.040, which requires a $50 application fee, an annual fee, a Sheriff's background check, and limits breeding to recognized breeds, with a household cap of three permits before a kennel license is required instead.
