If you breed dogs, every dog in your program is intact. In most places, that is not a problem. In some cities and counties, though, keeping an unaltered dog takes a special permit. These rules are called mandatory spay/neuter ordinances, and the permits are often called intact permits or unaltered dog permits.
This guide explains how these local laws work, who is usually exempt, and how they fit with state and federal licensing. It also covers what to do before you breed your next litter.
What Is a Mandatory Spay/Neuter Law?
A mandatory spay/neuter law requires dog owners to sterilize their pets by a certain age. Owners who want to keep a dog intact must qualify for an exemption or buy a permit. The goal of these laws is to cut down on unplanned litters and shelter crowding.
These rules are almost always local. They come from city councils and county boards, not state lawmakers or the federal government. One well-known example is Los Angeles, which adopted a mandatory spay/neuter ordinance in 2008 (Los Angeles Municipal Code Section 53.15.2). Other cities and counties around the country have passed their own versions. Each one sets its own rules, and no two are exactly alike.
Key point: Your state may have no spay/neuter mandate at all, while your city or county does. Always check your local animal control rules, not just state law.
How Intact Permits Usually Work
An intact permit is a local license that lets you legally keep an unaltered dog. Some places issue a permit for each dog. Others issue one breeder permit that covers your whole program. The details vary, but most permits share a few common features.
Common Permit Requirements
- A current dog license from your city or county
- Proof of rabies vaccination that is up to date
- A microchip registered to you
- Proof of purpose, such as breed registry papers, show records, or a breeder permit
- A yearly renewal and a permit fee set by local ordinance
- Litter limits or litter reports in some areas, such as reporting each litter or listing puppy buyers
Permit fees are set by each local government, and they change over time. Check your local fee schedule directly. Some areas charge more for an unaltered dog license than for a spayed or neutered dog, even where a full mandate does not exist. Our fees by state page covers state-level breeder license fees.
Common Exemptions
Most mandatory spay/neuter ordinances list groups of dogs that do not have to be altered. These often include:
- Dogs owned by holders of a local breeder permit
- Show or competition dogs with proof of recent participation
- Working dogs, such as police, service, herding, or hunting dogs
- Dogs that a veterinarian certifies cannot be safely sterilized for health reasons
- Puppies that are under the required age
- Dogs that are visiting the area for a short time
Never assume an exemption applies to you. Many require paperwork, such as a vet letter or show records, and some must be renewed each year.
How Local Permits Fit With State and Federal Licenses
Here is where many breeders get confused. An intact permit, a state breeder license, and a USDA license are three separate things. Having one does not replace the others.
Federal Rules
The USDA does not regulate spay or neuter. Its licensing rules cover who must hold a license under the Animal Welfare Act. Under 9 CFR 2.1(a)(3)(iii), breeders with more than four breeding females who sell puppies sight unseen generally need a USDA license. Breeders with four or fewer breeding females are exempt, even if they sell sight unseen (78 FR 57227). See our USDA licensing page for the full details.
State Rules
Some states require a state dog breeder license, including Missouri, Pennsylvania, Colorado, Ohio, Virginia, and others. Each state sets its own threshold, often based on the number of breeding dogs or litters per year. Other states have no state breeder license. Look up your state on our state pages (swap in your own state) to see the exact rules.
Local Rules
Your city or county may add its own layer on top. That can include an intact permit, a kennel permit, or zoning limits on how many dogs you can keep at home. A breeder in a state with a state license could still need a local intact permit for every adult dog.
Think in layers: Federal (USDA), then state, then county, then city. Check each layer separately. Meeting one does not mean you meet the others.
What These Laws Mean for Your Puppy Buyers
Spay/neuter laws do not just affect your own dogs. They can also affect the puppies you sell. If a buyer lives in an area with a mandate, they may have to alter the puppy by a certain age or get a permit. Many buyers do not know this.
It helps to tell buyers to check their local rules before they bring a puppy home. This is especially true if you sell a puppy with full breeding rights. A buyer who plans to show or breed may need a permit in their area.
Keep in mind that a spay/neuter clause in your sales contract is a private agreement, not a law. A limited registration with a breed club is also not a legal sterilization order. Your contract and local law are two different things. For help writing clear terms, see our guide to dog breeder contracts.
Steps to Stay Compliant
Follow these steps before you add a new dog or plan your next litter:
- Find your local animal control office. Search your city and county codes for words like "spay," "neuter," "unaltered," or "intact."
- Check both city and county rules. If you live in a city, both may apply. If you live in an unincorporated area, county rules usually control.
- Read the exemption list closely. Note any paperwork you must file to qualify.
- Apply for permits before breeding. Some areas will not issue a permit after a litter is born.
- Keep your records together. Store permits, vaccine records, microchip numbers, and vet letters in one place. Our record keeping guide can help.
- Confirm your state and USDA status. Use our USDA page and your state page to see if you need those licenses too.
- Set a renewal reminder. Most permits expire each year.
What Happens If You Do Not Comply?
Penalties depend on the local ordinance. Common results include citations, fines set by the local code, or an order to get a permit or alter the dog. Repeat violations may lead to bigger problems, especially if they connect to other issues like zoning or animal care complaints.
The best way to avoid trouble is to ask questions early. Local animal control staff can often tell you which permits you need. Get their answer in writing if you can.
Are Statewide Mandates Coming?
Lawmakers in some states have proposed statewide spay/neuter mandates in the past. As of this writing, spay/neuter mandates for privately owned dogs remain mostly local. Many states do require shelters and rescues to sterilize dogs before adoption, but those rules usually do not reach private breeders.
Watch for proposed bills in your state. A bill is not law until it is signed. You can follow new changes on our changelog and learn about related rules on our puppy mill laws page.
