California holds some of the most protective animal welfare regulations in the country, and dog breeding sits squarely at the center of that framework. Whether you breed one litter a year or operate a large-scale kennel, the rules governing your operation have grown significantly more detailed — and more enforced — in recent years.
Understanding dog breeding laws in California is not optional if you plan to breed and sell dogs in the state. From how the law defines a commercial breeder to what happens when you violate the rules, this guide walks you through every layer of regulation you need to know before your next litter arrives.
Who Is Considered a Commercial Dog Breeder in California
California draws a clear line between a hobby breeder and a commercial one, and which side of that line you fall on determines how many regulations apply to you. The distinction matters enormously for licensing, recordkeeping, and enforcement purposes.
Under the Polanco-Lockyer Pet Breeder Warranty Act, a “dog breeder” or “breeder” means a person, firm, partnership, corporation, or other association that has sold, transferred, or given away all or part of three or more litters or 20 or more dogs during the preceding 12 months that were bred and reared on the premises. If your operation falls below those thresholds, you are generally considered a hobby breeder and are not subject to the full commercial breeder framework.
Generally, a commercial dog breeder is defined as someone who breeds a large number of dogs — usually 20 or more — within a certain time frame, usually 12 months. This definition does not typically include a person who breeds a litter or two every year as a hobby, usually termed a “hobby breeder.”
The Polanco-Lockyer Act does not apply to pet dealers regulated under separate provisions, or to publicly operated animal shelters, humane societies, or privately operated rescue organizations.
Key Insight: Even if you do not meet the commercial breeder definition under state law, newer regulations effective January 1, 2026 extend certain obligations — including disclosure requirements and deposit rules — to anyone who breeds and transfers even a single dog to a California buyer.
Local jurisdictions can also impose their own definitions. In Los Angeles County, for example, a dog breeding license is an animal facility license issued to a person who breeds dogs commercially, and the applicant must comply with all licensing requirements, other applicable ordinances, and all federal and state laws, including Health and Safety Code section 122045 et seq.
If you are unsure whether your operation qualifies as commercial under your county’s rules, contact your local animal control agency directly. Requirements vary significantly from one jurisdiction to the next, and you are responsible for knowing which rules apply to you. You can also review California pet laws for a broader look at how the state regulates animal ownership.
Do You Need a License to Breed Dogs in California
The short answer is: it depends on where you live and how many dogs you breed. California does not issue a single statewide breeder license that covers all operations uniformly.
California does not issue a single statewide “breeder license.” Instead, requirements depend on your county and city. Most breeders need a kennel permit from their local animal control office, and some cities also require a business license if you breed more than one litter per year.
To find out what your area requires, contact your county animal control department. Requirements vary widely — Los Angeles County has different rules than San Diego or Sacramento.
Here is a summary of common permit types you may encounter across California counties:
| Permit Type | Who Needs It | Issuing Authority |
|---|---|---|
| Kennel Permit | Most breeders housing multiple dogs | County Animal Control |
| Dog Breeding License | Commercial breeders (county-defined) | County Animal Services |
| Breeder Permit (per female) | Any person breeding a female dog | County Animal Services (e.g., Tulare) |
| Business License | Breeders selling more than one litter/year | City/County Business Office |
| Seller’s Permit | Breeders selling more than two dogs/year | CA Dept. of Tax and Fee Administration |
| USDA License | Breeders selling sight-unseen (online/phone) | USDA APHIS |
Dog breeders in California must have a seller’s permit registered with the California Department of Tax and Fee Administration if they sell more than two dogs in a year.
Note that the City of Los Angeles has additional restrictions. As of May 27, 2024, a moratorium on the issuance of new dog breeding permits is in effect under Los Angeles Municipal Code Section 53.15.2(f). If you are located within city limits, check with LA Animal Services before assuming a breeding permit is available to you.
Also be aware that if you breed dogs and sell puppies sight-unseen — online, over the phone, or shipped — you may need a USDA license. This is a federal requirement separate from any state or local permit.
How to Get a Dog Breeder License in California
Because licensing is handled at the county and city level, the exact application process differs depending on where your facility is located. That said, most jurisdictions follow a similar sequence of steps.
- Contact your local animal control agency. This is your starting point. Ask specifically about breeder permits, kennel licenses, and any zoning requirements that apply to your property.
- Confirm zoning compliance. All kennels must operate in accordance with applicable zoning laws, and commercial, rescue, and boarding kennels typically require a special use permit.
- Complete the application. To obtain a permit, the applicant must fill out the appropriate application for each breeding female and be approved by Animal Services. In some counties, a separate application is required for each dog you intend to breed.
- Provide veterinary documentation. The applicable dog must have been examined by a veterinarian licensed in California within 90 days prior to the application and must be approved to breed. The dog must also be immunized against common communicable diseases, with current immunizations.
- Schedule and pass an inspection. After submitting your completed application along with payment, a site check will be conducted at random between the hours of 9 a.m. and 4 p.m., Monday through Saturday.
- Obtain your permit and display it. The breeder must list the permit number when advertising dogs for sale or other transfer and must disclose the permit number to all parties acquiring animals.
- Renew annually. Permits must be renewed annually. Failure to renew on time can expose you to the same penalties as operating without a permit.
Pro Tip: Some California counties offer free compliance workshops for breeders. These sessions explain local rules and answer specific questions — check with your animal control office to see if workshops are available near you.
If you operate in Tulare County, note that a commercial kennel may obtain no more than five breeding permits per calendar year. In La Puente and similar jurisdictions, each license authorizes the whelping of no more than one litter per female dog in any 12-month period and no more than one litter per domestic household in any 12-month period.
Breeders who also want to keep intact (unaltered) dogs must obtain an intact dog license in addition to any breeding permit. In the City of Los Angeles, owners intending to keep their dogs intact must purchase an intact license for $100.00 and qualify for one of the dog sterilization exemptions. The dog must also be microchipped.
Facility, Care, and Housing Standards for Breeders in California
California’s care and housing requirements for breeding dogs are among the most detailed in the country. Whether your operation is governed by state statute or local ordinance, you are expected to meet minimum standards that address the physical and medical wellbeing of every dog on your property.
Breeders must provide dogs with sanitary housing, adequate food, water, exercise, and veterinary care. These baseline requirements flow from the Polanco-Lockyer Pet Breeder Warranty Act and are reinforced at the county level through local ordinances.
The following care standards are widely enforced across California jurisdictions:
- Minimum breeding age: A female unaltered dog must be at least 12 months old before being bred.
- Minimum weaning age: Offspring may not be removed from the premises earlier than eight weeks of age, except for medical reasons ordered by a California licensed veterinarian.
- Whelping housing: Each pregnant dog must be housed separately at least three days before giving birth and be monitored at reasonable intervals. A dog who has just given birth must be provided with a contained nesting area and housed with her litter in their own run or enclosure until the newborns are weaned.
- Sanitation: Commercial pet breeders in California must provide a floor mat, rest board, or another device that can be kept sanitary. Staff must also wash their hands before and after handling any contagious or infectious dogs.
- Microchipping: All dogs must be microchipped or tattooed upon reaching the age of four months or prior to sale or transfer, whichever is earlier.
For facilities housing 51 or more sexually intact dogs over the age of one year, additional requirements apply. The facility must provide a written medical program, approved by a California licensed veterinarian, to prevent and control illness and parasitism. The program must include a regular de-worming schedule and a regular vaccination schedule against commonly transmitted canine diseases, and must be updated annually.
Large facilities also face staffing obligations. The animal facility must maintain adequate staffing 18 hours a day to attend to the animals. Whenever an animal is left unattended, the name, address, and telephone number of the responsible person must be posted in a conspicuous place at the front of the property.
Important Note: California’s AB 485 — the Pet Rescue and Adoption Act — bans pet stores from selling dogs sourced from commercial breeders. Direct breeder-to-buyer sales remain fully legal, but routing your puppies through a pet store is not permitted under state law.
On the sales side, no breeder shall knowingly sell a dog that is diseased, ill, or has a condition that requires hospitalization or nonelective surgical procedures. Violating this provision carries civil penalties separate from those imposed for housing or care violations. You can also review California dog bite laws to understand additional owner liability that may arise from your breeding operation.
Inspections and Recordkeeping Requirements in California
Staying compliant in California means more than meeting care standards — it also means keeping thorough records and being prepared for inspections at any time.
Recordkeeping obligations apply broadly. A breeder must maintain a written record on the health, status, and disposition of each dog for a period of not less than one year after disposition of the dog. The record must also include all of the information that the breeder is required to disclose pursuant to the Polanco-Lockyer Act.
County-level ordinances go further. In addition to the records required by California Health and Safety Code Sections 122050 and 122055 relating to dogs, breeding facilities must keep the following records for all dogs: the date and from whom the dog was acquired; the date of each litter birthed by each female animal; veterinary records; and the cause of death and the method of disposal.
The facility must maintain records on site demonstrating that an annual veterinary examination has been performed on each intact male or female dog over one year of age. These records must be available for review during any inspection.
Disclosure requirements at the point of sale are also mandatory. Every breeder must deliver to each purchaser a written disclosure containing the breeder’s name and address; if the breeder is USDA-licensed, the federal dealer identification number; the date of the dog’s birth and the date the breeder received the dog; and the breed, sex, color, and identifying marks at the time of sale.
The written disclosure must be signed by both the breeder certifying the accuracy of the statement and by the purchaser acknowledging receipt. In addition, all medical information required to be disclosed must also be communicated orally by the breeder to the purchaser.
Inspections are a routine part of California’s enforcement framework. For facilities with 51 or more sexually intact dogs over the age of one year, the Director may approve an application only if the applicant complies with additional requirements, and these facilities will be re-inspected more frequently. The frequency of re-inspections scales with the number of dogs housed:
- 51 to 75 dogs: one annual re-inspection; 76 to 100 dogs: two annual re-inspections; 101 to 125 dogs: three annual re-inspections; 126 to 150 dogs: four annual re-inspections; 151 or more dogs: five annual re-inspections.
Pro Tip: Digital records are acceptable in California. Many breeders now use spreadsheets or breeding software to track everything — just make sure you can produce the records quickly if requested during an inspection.
Knowingly providing false information or records relating to any animal is a misdemeanor. This applies to records submitted to animal control as well as documentation provided to buyers. Honest, accurate recordkeeping is both a legal obligation and your best protection during any enforcement review.

Federal Breeder Requirements That Apply in California
State and local rules are not the only framework governing your breeding operation. Federal law adds another layer of oversight that applies to certain California breeders based on how they conduct sales.
The Animal Welfare Act (AWA) is the primary federal statute. The only uniform animal welfare law is the federal Animal Welfare Act, which includes regulations for living conditions of certain animals and penalties for violations. Dogs are covered animals under the AWA, but the law’s reach is more limited than many breeders realize.
The Act exempts all retail pet stores and someone who does not profit more than $500 from the sale of a dog, cat, or any wild animal. Thus, savvy breeders can maneuver around the license requirement if they sell directly to the public or do not gross more than $500 per year.
The most significant federal trigger for California breeders is remote selling. You cannot buy puppies from other breeders and resell them online. If you sell online without in-person meetings, you likely need a USDA license as well. The USDA licenses dog dealers through its Animal and Plant Health Inspection Service (APHIS) program.
The AWA requires inspections through the Department of Agriculture’s Animal Care Program. However, since the federal law exempts those facilities that sell dogs directly to the public, a significant amount of breeding facilities go uninspected.
Importing dogs into California carries its own federal and state requirements. A person seeking to bring a dog into California for the purpose of resale or change of ownership must obtain a health certificate with respect to that dog that has been completed by a licensed veterinarian and is dated within 10 days prior to the date on which the dog is brought into the state.
As of January 1, 2026, the submission process for those health certificates changed significantly. Senate Bill 312 requires dog importers to electronically submit health certificates to the California Department of Food and Agriculture within 10 days of shipment. The certificates, which identify the breeder and document the dog’s health, will be made publicly available. The law gives consumers and law enforcement access to critical information needed to identify unethical breeding and transport practices.
Additionally, AB 519, authored by Assemblymember Marc Berman, prohibits both in-person and online pet brokers from selling dogs, cats, or rabbits under a year old. The bill defines a broker as a person or business that sells, processes, or transports a pet bred by someone else for profit. It carves out exceptions for shelters, rescues, and educational nonprofits teaching kids to care for animals. Service animals and those involved with government agencies, like police dogs, are also exempt.
If you breed dogs in another state and sell to California buyers, these rules apply to you. Beginning January 1, 2026, three new California laws significantly impact how dogs may be sold to California buyers — whether the breeder is located in-state or out-of-state. You can read more about how California regulates related emotional support animal laws and specific breed regulations such as American Bully laws in California.
Penalties for Violating Dog Breeding Laws in California
California takes enforcement seriously, and the penalties for violating dog breeding laws can be significant — financially and legally. Understanding what you are risking is a strong incentive to stay compliant before an inspector ever knocks on your door.
Civil penalties under the Polanco-Lockyer Act are tiered based on the nature and frequency of the violation:
- In lieu of other civil penalties, any breeder who violates the prohibition on selling diseased dogs shall be subject to a civil penalty of up to $1,000, or shall be prohibited from selling dogs for up to 30 days, or both.
- If there is a second offense, the breeder shall be subject to a civil penalty of up to $2,500, or a prohibition from selling dogs for up to 90 days, or both.
Pet store violations under AB 485 carry their own financial consequences. Stores that break the law face fines of $500 per animal. Each animal sold in violation of the law is counted separately, so a store that sells multiple commercially bred puppies in a single transaction can face compounding fines quickly.
Local-level penalties mirror and often exceed state minimums. A local animal control agency is required to only issue a nonmonetary warning citation for a first violation. For a second or subsequent violation, the agency must establish civil penalties of not less than $250 per violation.
Even first-time violations can cost thousands of dollars. If animal control finds multiple violations during one inspection, each issue counts separately — three violations equals three fines.
Criminal liability is also on the table in serious cases. Knowingly providing false information or records relating to any animal is a misdemeanor. Operating a kennel without the required permits, violating zoning laws, or engaging in prohibited broker activity under AB 519 can all escalate to criminal charges depending on the circumstances and the jurisdiction.
Common Mistake: Many breeders only realize they are breaking rules when animal control shows up. By then, it is too late to avoid penalties. Do not wait for an inspection to get compliant — review your permits, records, and contracts now.
AB 506 violations add consumer protection consequences to the mix. AB 506 voids any pet contracts that include a nonrefundable deposit or fail to disclose the pet’s medical information and breeder origin. A voided contract means you may lose the right to enforce your sale terms entirely — including payment.
The pattern across all of California’s enforcement mechanisms is consistent: California does not take breeder violations lightly. The state has always been aggressive about animal welfare enforcement, and with AB 506 and SB 312 in place, penalties are tougher than ever.
If you are concerned about how your operation measures up, review your local county ordinances alongside state law. Resources like California dog leash laws, pit bull laws in California, and German Shepherd laws in California can give you a broader picture of how the state approaches dog ownership and regulation. For questions specific to your situation, consulting a licensed California attorney or your county animal control office is always the most reliable path forward.
Staying Compliant as a California Dog Breeder
Dog breeding laws in California operate on multiple levels simultaneously — state statute, local ordinance, and federal regulation can all apply to your operation at the same time. Knowing which rules govern you is the first step, and the second is building systems to meet them consistently.
The most important actions you can take right now include confirming your local permits are current, updating your sale contracts to remove nonrefundable deposit language, ensuring every dog in your facility is microchipped and has up-to-date veterinary records, and maintaining written disclosures ready for every buyer. If you import dogs from out of state or sell remotely, verify that your health certificate submission process complies with SB 312 and that you hold any required USDA licensing.
California’s regulatory environment is not getting simpler. The 2026 legislative package made that clear. Breeders who treat compliance as an ongoing practice — not a one-time checkbox — are the ones best positioned to operate without interruption.
