Dog Breeding Laws in Illinois: What You Need to Know Before You Breed
June 13, 2026
If you breed dogs in Illinois and sell them, state law has a clear message: you need a license before you open your doors. Illinois takes dog breeding regulation seriously, placing it under a dedicated statutory framework that covers everything from how your kennels are built to how you document every puppy that leaves your facility.
Understanding dog breeding laws in Illinois means working through both state and federal requirements, knowing exactly where the exemptions begin and end, and keeping your facility inspection-ready year-round. This guide walks you through every layer of that legal framework so you know precisely what is expected of you.
Who Is Considered a Commercial Dog Breeder in Illinois
Under the Illinois Animal Welfare Act (225 ILCS 605), anyone who breeds dogs and sells them is considered a “dog breeder” and must get a license from the Illinois Department of Agriculture. The definition is intentionally broad — it captures individuals, partnerships, corporations, and any other legal entity that produces and sells dogs.
However, the law does draw a meaningful line for small-scale breeders. A person who owns, has possession of, or harbors five or fewer females capable of reproduction shall not be considered a dog breeder. This threshold is specifically about reproductive females, not your total number of dogs. If you have six intact females on your property and you sell puppies, you cross into licensed breeder territory regardless of how few litters you produce per year.
Key Insight: The five-female threshold applies to females “capable of reproduction.” A spayed female does not count toward that number, but an intact female does — even if she has never been bred.
The Illinois Department of Agriculture’s Bureau of Animal Health and Welfare has the statutory authority to license and inspect pet shop operators, dog dealers, kennel operators, cat and dog breeders, animal control facilities, animal shelters, day care operators, guard dog services, and horse rescues. As a breeder, you fall within that licensing universe the moment you exceed the exemption threshold.
It is also worth noting how the law distinguishes breeders from dealers. A person who sells only dogs that he has produced and raised shall not be considered a dog dealer under this Act. If you breed and sell your own dogs, you are a breeder — not a dealer. Dealers, by contrast, buy dogs from others and resell them, which triggers a separate license category. You can also explore how Illinois pet import laws interact with dealer activity if you bring dogs into the state from outside.
Do You Need a License to Breed Dogs in Illinois
Except as provided in subsection (b) of this Section, no person shall engage in business as a pet shop operator, dog dealer, kennel operator, day care operator, dog breeder, or cat breeder or operate a guard dog service, an animal control facility, or animal shelter, in this State without a license therefor issued by the Department. That language leaves very little room for ambiguity.
The short answer is yes — if you breed dogs and sell them and you have more than five intact females, you need a license. Illinois requires dog breeders to be licensed by the Illinois Department of Agriculture under the Animal Welfare Act. Anyone who breeds dogs and sells them must hold a valid license, unless they own five or fewer females capable of reproduction.
Important Note: The exemption covers only the licensing requirement under the state Animal Welfare Act. Local municipalities may still require their own permits, kennel licenses, or zoning approvals even if you fall below the state threshold.
Kennel regulations vary by industry in Illinois, but all fall under the state’s Animal Welfare Act. Commercial kennels, boarding facilities, breeders, pet shops, and shelters must be licensed through the Illinois Department of Agriculture, meet sanitation and housing standards, and undergo inspections. If you operate in more than one of those categories — for example, you breed dogs and also board dogs for other owners — you may need a separate license for each activity.
For tax purposes, breeders selling dogs as pets are required to register with the Illinois Department of Revenue and collect and remit sales-related taxes where applicable. Licensing under the Animal Welfare Act does not substitute for your tax registration obligations. These are parallel requirements, and you need to satisfy both.
How to Get a Dog Breeder License in Illinois
The licensing process runs through the Illinois Department of Agriculture and follows a structured sequence. To apply for a license, you must submit an application to the Illinois Department of Agriculture’s Bureau of Animal Health and Welfare. The license application fee is $350, and this fee is non-refundable.
Here is the step-by-step process for obtaining your initial breeder license:
- Review the Animal Welfare Act and Rules — Read 225 ILCS 605 and the accompanying Animal Welfare Rules in full before you apply. Understanding the standards in advance prevents costly surprises during your inspection.
- Determine your license type — Determine which application or applications you are applying for. A separate application must be completed for each required license. There is a $350 application fee for each license type.
- Submit your application and fee — Submit your completed application and the non-refundable $350 fee to the Bureau of Animal Health and Welfare. Note that this application cannot be used to renew a license and will not be processed if used for that purpose.
- Pass the preliminary inspection — Department personnel will contact you to conduct a preliminary inspection and answer any questions you might have regarding the Act and its requirements as a prerequisite to final processing and issuance of your license.
- Receive your license and note the expiration date — The license expires annually on June 30th. You must renew before that date each year.
The $350 fee applies to each license type, so if you operate in multiple categories — such as both a breeder and a kennel operator — you may need to pay the fee for each license. The $350 fee is due each year when you renew your license.
Pro Tip: Do not wait until your facility is fully built to review the Animal Welfare Rules. Schedule a pre-application consultation with the Bureau of Animal Health and Welfare before construction begins so your enclosures, ventilation, and drainage systems are compliant from day one.
Local counties or municipalities may also have additional rules, so it is important to verify requirements in your area before opening or expanding a kennel. Check with your city clerk and county zoning office in addition to completing the state application. You may also find it useful to review how other Illinois animal laws are structured, such as backyard chicken laws in Illinois, which similarly layer state and local requirements.
Facility, Care, and Housing Standards for Breeders in Illinois
A license is only the beginning. Once licensed, you are obligated to maintain your facility to the standards set by the Animal Welfare Act and its rules at all times — not just during scheduled inspections.
The regulations apply to all state-licensed breeders and include sanitation and safety requirements; requirements for enclosures to be safely constructed, be large enough for the animals, and have adequate lighting and ventilation; provisions to protect animals from dangerous weather conditions; and requirements for providing animals with proper exercise, hygiene, and physical examinations.
On the housing side, dogs must have enclosures sized appropriately for their body weight. Local ordinance examples that mirror state standards provide useful reference points:
| Dog Size | Minimum Cage Dimensions | Minimum Floor Space |
|---|---|---|
| Small (up to 25 lbs) | 3 ft x 4 ft | 12 sq ft |
| Medium (25–50 lbs) | 4 ft x 5 ft | 20 sq ft |
| Large (over 50 lbs) | 4 ft x 6 ft | 24 sq ft |
Intact males and females shall be housed separately unless a planned breeding is taking place. Nursing mothers and litters are to remain co-located, but separate from other animals until the litter is at least eight weeks of age.
Outdoor housing carries its own set of obligations. Licensees are not permitted to keep a dog in an outdoor enclosure if it is unable to tolerate the prevalent temperatures, based on the animal’s own characteristics such as breed, body condition, and environmental acclimation. Moreover, those using outdoor enclosures must take effective measures to ensure that climatic or ambient temperature threats to the health and welfare of dogs are eliminated.
Veterinary care requirements are equally detailed. Licensees must have a working relationship with a veterinarian who will provide recommendations on vaccinations and deworming. Each dog must receive a complete physical exam by a licensed veterinarian within 30 days of intake or prior to sale or adoption, whichever occurs first, and thereafter on an annual basis if the animal has not been sold or adopted. Breeding animals shall receive an annual physical examination by a licensed veterinarian as long as the dog is part of the facility’s breeding population.
Grooming is also a codified obligation, not just a best practice. Licensees are required to provide grooming, as necessary, to prevent matting of coat and accumulation of fecal, urine, or other material in an animal’s coat, and this shall include nail trimming to ensure that nails do not injure the dog.
Exercise is a non-negotiable daily requirement. Licensees must provide animals an opportunity for daily exercise and are required to maintain a daily exercise log. That log becomes part of your recordkeeping and is subject to inspection review.
Common Mistake: Many new breeders underestimate the fire safety requirement. Kennel operators must have either a fire alarm system or fire sprinkler system, or must have staff present at all times when dogs or cats are on the premises. Make sure your facility meets one of these three options before your preliminary inspection.
Canine brucellosis testing is another area where Illinois rules have been strengthened. The requirement for annual testing for canine brucellosis has been expanded from sires to all breeding animals. Every dog in your active breeding population must be tested annually, and you must keep documentation of those results.
Inspections and Recordkeeping Requirements in Illinois
Inspections are a permanent feature of licensed breeding operations in Illinois, not a one-time hurdle. The Illinois Department of Agriculture has the authority to inspect all licensed facilities. Inspections check that your facility meets the health, housing, and sanitary standards required by the Animal Welfare Act. Annual inspections are standard, and the Department can also conduct unannounced inspections at any time.
Your recordkeeping obligations are equally ongoing. All licensees under this Act shall maintain records of the origin and sale of all dogs, and such records shall be made available for inspection by the Secretary or the Department upon demand. This is not a suggestion — failure to produce records on demand is itself a violation of the Act.
The records you must maintain include:
- The origin of every dog in your facility
- Vaccination status and veterinary examination records for each animal
- Sales and adoption records, including buyer information
- Daily exercise logs
- Canine brucellosis testing results for all breeding animals
- Proof in proper form of purebreds and their pedigree, and evidence of such proof must be provided to any person acquiring a dog from a licensee under this Act.
Licensees must maintain a record of all completed physical exams, which shall be made available for inspection. Keep these records organized and accessible. Inspectors may ask for them at any point during a visit, announced or otherwise.
Local jurisdictions can add their own reporting layers. All licensed breeders shall cooperate and provide information to the administrator including sales, adoptions, source, dispositions, number of litters, microchip numbers and ownership of dogs or cats, a minimum of one time annually. Check with your county or municipal authority to determine whether a local annual report is required in addition to the state requirements.
Pro Tip: Build your recordkeeping system before your first litter arrives. A spreadsheet or dedicated kennel management software that tracks intake dates, veterinary visits, vaccination records, and sale information will make inspection days far less stressful and help you catch any gaps in compliance early.
Proper disposal of deceased animals is also a legal requirement. All deceased animals are to be properly disposed of within twenty-four hours and in accordance with Illinois state law. Contact your local animal control authority if you are unsure of the approved disposal methods in your county. You may also want to review Illinois roadkill laws for additional context on how the state handles animal remains.
Federal Breeder Requirements That Apply in Illinois
State licensing does not eliminate your federal obligations. Depending on how you sell your dogs, you may also need a license from the United States Department of Agriculture.
The USDA requires a federal license under the Animal Welfare Act for anyone who maintains more than four breeding females and sells dogs sight-unseen — online, by phone, or by mail. This regulation is enforced by APHIS, the Animal and Plant Health Inspection Service.
The key distinction at the federal level is how the sale takes place, not just how many dogs you have. Small breeders with four or fewer breeding females are exempt, as are those who sell only face-to-face directly to the public. If every buyer comes to your facility and physically sees the dog before purchasing, you may not need a federal license even if you have more than four breeding females.
Under the USDA rule, the seller, the buyer, and the animal must all be physically present in the same location so the buyer can personally observe the dog before purchasing it. Selling through a website with photos, shipping puppies to buyers, or completing a sale by phone or email all qualify as sight-unseen sales and trigger the federal licensing requirement.
| Situation | State License Required? | USDA License Required? |
|---|---|---|
| 5 or fewer intact females, sell in person only | No | No |
| 6+ intact females, sell in person only | Yes | No (if 4 or fewer breeding females) |
| 5+ breeding females, sell sight-unseen | Yes | Yes |
| 4 or fewer breeding females, sell sight-unseen | No (state exemption) | No (federal exemption) |
The USDA issues two main license types for people who deal in dogs. If you have more than four breeding females and sell sight-unseen, you need a USDA Class A Breeder license. The USDA issues this license for people who breed and raise dogs on their own property and sell them — it is the license most dog breeders need.
On the federal fee structure, since 2023, USDA animal welfare licenses use a simplified flat fee structure: all licenses are now three-year licenses with a flat processing fee of $120. There is no separate inspection fee — inspections are included. Applications and fees can be submitted online.
Federal law requires certain businesses that use animals — like zoos, research institutions, and commercial pet breeders — to meet minimal animal care standards found in the Animal Welfare Act. The U.S. Department of Agriculture is responsible for licensing these businesses and inspecting them to make sure they comply.
USDA-licensed facilities are subject to unannounced inspections by APHIS. A pre-license inspection is required before your initial license is granted. After licensing, APHIS can inspect at any time without notice. Federal inspection reports are also public record, which means your compliance history is visible to anyone who looks you up.

Penalties for Violating Dog Breeding Laws in Illinois
Illinois does not treat Animal Welfare Act violations lightly. The Department has broad authority to respond to non-compliance, and the consequences escalate with the severity and frequency of violations.
The Illinois Department of Agriculture may refuse to issue or renew or may suspend or revoke a license due to an individual operating without a proper license under the Act. This means that even if you are already licensed, operating outside the scope of that license — for example, running a boarding operation without a separate kennel operator license — can put your breeder license at risk.
Local governments may have their own penalties for violating local kennel ordinances. The state takes animal welfare seriously, and repeated violations can lead to being permanently banned from holding a license.
At the local level, the consequences can be swift and cumulative. Each day a person fails to comply constitutes a separate offense. A single unresolved violation does not stay as one violation — it multiplies daily until corrected.
Repeat offenders face the harshest outcomes. If a breeder is found to be guilty of any portion of the relevant section three times, their license will be immediately revoked and animals will be surrendered to animal control, and they shall not own, possess, or harbor any dogs or cats for a period of three years.
Important Note: Surrendering animals to animal control is not just a financial loss — it can also result in legal proceedings under the Illinois Humane Care for Animals Act if neglect or cruelty is documented during the seizure. Keeping your facility in compliance is always less costly than the alternative.
At the federal level, 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. The law provides criminal penalties, civil penalties, and revocation of permits for violations of the AWA. Federal enforcement runs parallel to state enforcement, and a violation of the federal AWA does not preclude separate state-level action.
To stay on the right side of the law, treat every inspection as if it were unannounced, keep your records current at all times, and address any deficiencies immediately. If you have questions about your specific compliance status, contact the Illinois Department of Agriculture’s Bureau of Animal Health and Welfare directly at (217) 782-4944. You may also find it helpful to review other Illinois animal-related regulations, such as barking dog laws in Illinois and neighbor cat laws in Illinois, to understand the broader regulatory environment for dog and animal ownership in the state. Breeders in neighboring states can compare requirements by reviewing dog laws in Ohio or dog laws in Michigan for additional context.
