There is no single law for dog breeders in the United States: a hobby breeder in one state can need nothing beyond a kennel permit, while the same breeder with the same dogs a few miles away, or selling in a different way, can need a federal license, a state license and a written warranty for every buyer.
The most important first
- Think in three layers: the federal Animal Welfare Act, enforced by USDA APHIS; state law, which varies widely; and county or city rules such as zoning, kennel permits and limits on the number of dogs.
- A USDA license is not about size alone. APHIS exempts breeders who keep four or fewer breeding females and sell only offspring born and raised on their premises, and retail sales where buyer, seller and dog are physically together in the same place.
- Selling a puppy sight unseen is the trigger to watch: if you keep more than four breeding females and ship puppies to buyers who have not seen them, the American Kennel Club notes you may need a USDA license.
- Around twenty states have pet purchaser protection laws, often called puppy lemon laws. Some apply directly to breeders: California’s covers anyone who sold three or more litters or 20 or more dogs in the previous 12 months.
- Rules change, and thresholds differ from state to state. Confirm what applies to you with your state agency, your county or city, and a lawyer licensed in your state.
Rules last checked: November 1, 2026
We checked this page against the official sources listed below on the date above. Rules can change after that date, and no single page can cover every situation, so something that matters to you may have been amended since, or may not be covered here at all. Before you rely on it, check these as well:
- Your county and city: zoning, kennel or breeder permits, limits on the number of dogs and intact-animal rules are local and do not appear on state or federal websites.
- Recent changes in your state: breeder licensing thresholds and pet purchaser protection laws are amended regularly. Read the current text on your state’s own website.
- The buyer’s state: a sale into another state can bring that state’s entry and sale requirements into play as well as your own.
- Business and tax registration: selling puppies regularly can mean a business license, sales tax collection or income tax obligations, depending on your state and locality.
- Your registry: AKC, UKC and other registries have their own rules on registration, record-keeping and inspections that apply on top of the law.
Check the current rules at the source before each breeding year and before any sale that is new to you, such as a first litter or a first buyer in another state or country. Ask the authority in writing when the answer matters, and keep a dated note of what you checked and what you were told.
Three layers of rules
The general picture is in laws, regulations and kennel clubs. In the US it has a particular shape. At the top sits the federal Animal Welfare Act, which the American Kennel Club’s 2023 policy analysis describes as licensing certain breeders, setting minimum care standards and providing for inspections through USDA’s Animal and Plant Health Inspection Service. Below it, every state prohibits animal cruelty, and many have their own programs for commercial breeders, with definitions that differ from one state to the next. Below that again are county and city ordinances. Registries such as the AKC and the UKC add their own rules for registration and record-keeping, but those are conditions of membership rather than law.
The practical consequence is that “am I a commercial breeder?” has no single answer. You can be below the federal threshold, above your state’s and in breach of a city ordinance, all at once.
When a USDA license applies
APHIS licenses breeders as Class A, a breeder whose business consists of dogs and other regulated animals bred and raised on their own premises, and dealers and brokers as Class B. Its guidance lists situations that do not require a license, and two of them cover most small breeders: keeping a total of four or fewer breeding female dogs and selling only the offspring, born and raised on your premises, as pets or for exhibition; and retail sales, including adoptions, where the buyer, the seller and the dog are physically together in the same place so that the buyer can see the dog before taking it.
The second exemption is the one breeders lose without noticing. Shipping a puppy to a buyer who has only seen photographs and video is not a face-to-face sale. The AKC’s analysis summarizes the rule as applying to someone who keeps more than four breeding females and sells pets sight unseen, and points out that “breeding female” is not defined in writing and is decided case by case. If your plans include shipping puppies or using a flight nanny, ask USDA Animal Care before the litter, not after. Every dog entering the United States must be at least six months old, have a microchip that a universal scanner can read, and arrive with a CDC Dog Import Form receipt; extra rabies requirements apply to dogs that have been in a high-risk country. Check the CDC’s Dog Importation Navigator before you plan an import. The wider international side of shipping is in export and international sales.
State breeder licensing
Many states license commercial breeders, but they draw the line in different places: the number of intact females, the number of litters, the number of dogs sold, or a combination. The AKC’s 2023 analysis gives examples. Wisconsin covers breeders selling 25 or more dogs a year from more than three litters. Texas originally required a license at 11 or more intact females plus 20 or more sales a year, and a 2023 amendment lowered the threshold to five intact females and removed the sales requirement. Several states also cap the number of dogs a breeder may keep, at 50 in Oregon, Virginia and Washington and 75 in Louisiana. These figures date from the AKC document and may since have changed, so treat them as examples of how varied the rules are rather than as current law.
Find your own state’s rule on the website of the agency that runs the program, often the department of agriculture or a licensing department, and write down the exact threshold. Then check where your plans for the next two years would put you.
Puppy lemon laws: what buyers can claim
About twenty states have pet purchaser protection laws. They typically give a buyer a short period, usually 7 to 14 days depending on the state, to have a veterinarian certify that the dog was ill at the time of sale, a longer period for congenital or hereditary conditions, and a choice of refund, exchange or reimbursement of veterinary costs. Some apply only to pet stores and dealers; others reach breeders directly. Two examples show the range.
California. The Polanco-Lockyer Pet Breeder Warranty Act defines a dog breeder as anyone who sold, transferred or gave away all or part of three or more litters, or 20 or more dogs, bred and reared on their premises during the preceding 12 months. A buyer has remedies if a California-licensed veterinarian certifies in writing that the dog became ill within 15 days from an illness that existed at delivery, or has a congenital or hereditary condition diagnosed within one year. The buyer can choose to return the dog for a refund plus sales tax, with veterinary fees up to the purchase price; to exchange it, with veterinary fees; or to keep it and recover veterinary fees of up to 150% of the purchase price plus sales tax. If the dog dies within 15 days of delivery, the law presumes the illness existed at the time of sale. The breeder must also give each buyer a signed written disclosure covering, among other things, the breeder’s name and address, the dog’s birth date, breed, sex and color, the parents’ registration details if sold as registrable, vaccination and worming records, and either a statement that the dog has no known disease or hereditary condition or a record of known conditions.
Florida. Florida’s statute applies to any “pet dealer”, defined as anyone who sells more than three litters or 30 dogs or cats a year, whichever is greater, which includes breeders who sell directly to the public. Every dog offered for sale must be accompanied by an official certificate of veterinary inspection, with the veterinary examination no more than 30 days before sale; dogs under eight weeks may not be offered for sale; and the statute lists the vaccinations and dewormings required. Buyers have 30 days to have a veterinarian certify an illness present at the time of sale, and one year for congenital or hereditary disorders. Deadlines are short on both sides: the buyer must notify the seller within seven business days of the veterinarian’s finding, and the seller must refund or exchange within ten business days of receiving the certification.
Even where no specific statute applies, a sale is still a contract, and general consumer and commercial law can apply to breeders as sellers. That is why your own sales contract should match, and never undercut, whatever your state requires, and why the records in the pre-sale health checklist matter.
Selling across state lines
Requirements for dogs entering a state are set by that state, and they can include a certificate of veterinary inspection and vaccination records with their own deadlines. If a puppy is sold into another state, the buyer’s state rules can apply as well as yours: Florida’s statute, for example, covers dogs transported into the state for sale. Check the destination state’s requirements with its state veterinarian’s office and your own veterinarian before agreeing a date, and remember that a sale completed without the buyer present may also change your federal position.
County and city rules
Local rules are where many breeders actually run into trouble: zoning that does not allow a kennel in a residential area, a kennel or breeder permit, a limit on the number of dogs per household, intact-animal permits, or mandatory spay and neuter ordinances, which the AKC analysis notes it opposes. None of these is visible from state or federal websites. Call your county or city planning or animal services department, describe your plans honestly, and get the answer in writing.
In practice
A breeder in a small town keeps three bitches and sells every puppy in person, so assumes no rules apply. A neighbor’s complaint about barking brings an animal control visit, which reveals that the town limits households to four dogs without a kennel permit, and the breeder has five. Getting the permit takes two months and a zoning hearing. The breeder now keeps a one-page record of every rule that applies, federal, state and local, with the date each was last checked.
(Illustrative, composite scenario.)
A short checklist for US breeders
- Count your breeding females and decide how you will sell. More than four, plus any sight-unseen sales, means asking USDA Animal Care whether you need a license.
- Find your state’s breeder licensing threshold and its pet purchaser protection law, if it has one, and read who it covers.
- Check zoning, kennel permits and dog limits with your county or city.
- Make sure your written disclosure, health records and contract meet your state’s requirements — see vet checks, microchipping and registration.
- For every buyer in another state, check that state’s entry and sale requirements before agreeing a date.
- Review your liability and insurance position, as in insurance and liability.
- Add all of this to your pre-breeding regulatory checklist and recheck it every year.
What the kennel clubs say
Neither the AKC nor the UKC is an FCI member.
AKC: a dam must be at least 8 months and no more than 12 years old at mating, and a sire at least 7 months, according to the AKC’s litter-registration glossary. Sires with seven or more lifetime litters, or more than three in a year, need a DNA profile.
UKC: if the dam is under 10 months or over 10 years, or the sire under 8 months or over 12 years, at breeding, the UKC may require DNA profiling of the parents and at least one puppy.
Not confirmed, but worth noting: the AKC ages above come from its online glossary; the full Rules Applying to Registration and Discipline was not confirmed for this box.

Work on it
A few minutes here will teach you more than re-reading the article.
Ask yourself
- If USDA asked tomorrow how many breeding females I keep and how I sold my last litter, would any of those sales count as sight unseen?
- Do I know my state’s breeder licensing threshold, or only roughly where it is?
- Does my contract give my buyers less than my state’s lemon law already gives them?
Find out & check
- Look up your state’s breeder licensing program and pet purchaser protection law on the state’s own website, then confirm with a lawyer licensed in your state how they apply to your plans.
Do one thing
- Write a one-page list of every federal, state and local rule that applies to you, with the date you checked each one.
