Pennsylvania has built one of the most detailed dog breeding regulatory frameworks in the entire country — and if you breed dogs in the state, those rules apply to you whether you run a large commercial operation or simply have a few litters a year.
Understanding exactly where the thresholds fall, what licenses are required, and what inspectors look for can mean the difference between a compliant operation and costly penalties. This guide walks you through every layer of Pennsylvania’s dog breeding laws, from state kennel licensing to overlapping federal requirements.
Who Is Considered a Commercial Dog Breeder in Pennsylvania
Pennsylvania draws a clear line between non-commercial and commercial breeders, and the distinction shapes nearly every obligation you face. A non-commercial kennel is a breeder who only sells directly to buyers and transfers no more than 60 dogs per year. Once you cross that line, the classification changes.
A commercial kennel is one that breeds dogs and either sells more than 60 dogs per year, sells any dogs at wholesale, or both. Selling even a single dog to a dealer, broker, or pet store — rather than directly to a retail buyer — can push you into the commercial category regardless of your total volume.
The kennel threshold itself is also worth understanding before you ever sell a dog. You need a kennel license if more than 25 dogs have been on your property within a calendar year. This includes adults and puppies. If, for example, you have 3 female dogs that have a total of 24 puppies in one calendar year (3 adults + 24 puppies, equals 27 dogs), you are required by law to get a kennel license.
Key Insight: The 26-dog threshold counts every dog that passes through your property in a calendar year — not just how many you own at one time. A small hobby breeder with three adult dogs can easily cross this line after a single litter season.
There are two types of kennels — non-commercial and commercial — which have differing requirements. The non-commercial kennel type includes rescue network kennels, research kennels, pet shop kennels, private kennels, dealer kennels, humane societies, associations for the prevention of cruelty to animals, municipal holding pens, and service dog kennels. If your operation grows beyond those categories or volume limits, you move into commercial kennel territory with stricter standards and higher fees.
It is also worth noting that kennel regulations in Pennsylvania can vary from county to county and often depend on factors like the number of dogs you have, the kennel’s size, and whether it’s for personal or commercial use. Local zoning rules may impose additional restrictions on top of state law, so checking with your county planning department is always a smart step. You can learn more about how local rules interact with state law in our overview of kennel zoning laws in Pennsylvania.
Do You Need a License to Breed Dogs in Pennsylvania
Pennsylvania has one of the most detailed dog breeder licensing systems in the country. The short answer for most active breeders is: yes, you almost certainly need some form of license.
You must have a kennel license if you operate a facility that keeps, harbors, boards, shelters, sells, gives away, or transfers a total of 26 or more dogs in any one calendar year. That license comes from the Pennsylvania Department of Agriculture’s Bureau of Dog Law Enforcement.
Beyond the kennel license, individual dog licensing is a separate requirement. Every dog in Pennsylvania over 12 weeks old also needs an individual dog license or must be covered under a kennel license. If you hold a valid kennel license, your dogs can be covered under it rather than licensed individually.
You also need a sales tax license if you sell any dogs or puppies at retail in Pennsylvania. This is a separate obligation administered through the Pennsylvania Department of Revenue, not the Department of Agriculture.
Important Note: All kennel licenses expire on December 31 each year and must be renewed annually. Operating after that date without a valid license puts you in violation of Pennsylvania’s Dog Law.
Vaccination requirements run alongside licensing. A current rabies certificate and dog license are required for all dogs while on the kennel property. You can administer your own rabies vaccinations if you have a commercial or non-commercial kennel license and if you pass a rabies vaccination test given by PA Dog Law. However, that only applies to the dogs when they are on your property. If you send your dogs elsewhere for boarding or breeding, they will need a valid rabies vaccine given by a licensed vet.
One additional rule affects sellers directly: kennels selling or adopting dogs at retail to the public are responsible for disclosing breeder information, vaccination and medical documentation, and any known bite attacks on a human or a domestic animal. This disclosure requirement was strengthened when Governor Josh Shapiro signed Senate Bill 746 into law in October 2023, updating Pennsylvania’s Dog Law with broader consumer protections.
How to Get a Dog Breeder License in Pennsylvania
You apply to the Pennsylvania Department of Agriculture, Bureau of Dog Law Enforcement. Applications are available on the PA Department of Agriculture website, and you must apply on or before January 1 of each year. You will need to provide information about your facility, the number of dogs, and your veterinary care plan.
New facilities must pass an inspection before getting a license. This pre-license inspection verifies that your housing, sanitation, and care practices already meet state standards before you are approved to operate. Plan your facility construction and setup with that inspection in mind.
License fees are structured by kennel class and type. Kennel license fees depend on the class and type of kennel. Approximate fees are: Class I (up to 50 dogs) is about $100; Class II (51–100 dogs) is about $250; higher classes for larger operations go up to $625 or more. These figures are approximate; confirm current fee schedules directly with the Bureau of Dog Law Enforcement, as the 2023 Dog Law update authorized fee adjustments.
| Kennel Class | Dog Capacity | Approximate Annual Fee | Kennel Type |
|---|---|---|---|
| Class I | Up to 50 dogs | ~$100 | Non-commercial or commercial |
| Class II | 51–100 dogs | ~$250 | Commercial |
| Class III+ | 100+ dogs | $625 or more | Commercial |
A separate license shall be required for each type of kennel and every location at which a kennel is kept or operated. If you run multiple kennel types — for example, a breeding kennel and a boarding kennel at the same address — each requires its own license and inspection.
When two or more licensed kennels are operated by the same person at the same location, each kennel shall be inspected and licensed as required by law. The total number of dogs housed, kept, harbored, boarded, sheltered, sold, given away, or transferred in or by all of the kennels operated by that person at that location shall be counted to determine whether those kennels meet the definition of “commercial kennel.”

Facility, Care, and Housing Standards for Breeders in Pennsylvania
The truly unique feature of the Pennsylvania law is the degree to which facility requirements are specified directly in the legislation. Rather than leaving standards vague, the state sets precise, measurable requirements for enclosure size, temperature, lighting, sanitation, and more.
Space requirements are calculated using a mathematical formula tied to each individual dog’s size. A dog that measures 24 inches from the tip of its nose to the base of its tail has 6 inches added to that number, giving a sum of 30 inches. Squaring that sum gives a product of 900 square inches. Dividing that product by 144 gives a quotient of 6.25. That means 6.25 square feet is the minimum amount of floor space that must be provided to that particular dog.
Primary enclosures shall be constructed and maintained to provide sufficient space to allow each dog to turn about freely and to stand erect, sit, and lie down in a comfortable, normal position. Enclosure height must also meet minimums: the interior height of a primary enclosure shall be at least 6 inches higher than the head of the tallest dog in the primary enclosure when it is in normal standing position.
Feeding and water rules are equally specific. Dogs kept in kennels shall be fed at least once each day unless otherwise directed by a veterinarian. The food shall be free from contamination or disease, and shall be of sufficient quantity and nutritive value to maintain the health of the dogs. If potable water is not accessible to the dogs in their primary enclosures, potable fluids shall be offered to the dogs at least 6 hours daily unless otherwise directed by a veterinarian.
Pro Tip: Pennsylvania’s space formula applies per dog, not per enclosure. If you house multiple dogs together, calculate the minimum floor space for each dog individually and add those figures together to find the total enclosure size required.
Temperature and housing conditions are also regulated in detail. Dogs that are not acclimated to the outdoor temperatures prevalent in the area or region where they are maintained, breeds of dogs that cannot tolerate the prevalent outdoor temperatures without stress or discomfort (such as short-haired breeds in cold climates), and sick, infirm, aged, or young dogs may not be kept in outdoor facilities unless that practice is specifically approved by the attending veterinarian.
Lighting in indoor facilities must be functional and consistent. Lighting in indoor housing facilities shall be sufficient to allow observation of the physical condition of the dogs so housed, and to allow observation of the sanitary condition of the indoor housing facility. Dogs housed in these facilities shall be provided a regular diurnal lighting cycle.
Segregation rules apply to adult dogs: adult dogs shall be segregated by sex except for health, welfare, or breeding reasons. Nursing mothers receive additional protections, with each bitch with nursing puppies provided with an additional amount of floor space, based on her breed and behavioral characteristics, and in accordance with generally accepted husbandry practices as determined by the attending veterinarian.
One additional care rule protects buyers: puppies must be at least 8 weeks of age before they can be sold, transferred, or given away. This minimum age rule applies to all breeders regardless of kennel class. Pennsylvania’s animal cruelty laws also run parallel to kennel standards, and violations of care requirements can trigger cruelty charges in addition to Dog Law penalties.
Dogs imported into PA kennels must be isolated for at least 14 days. This quarantine requirement, added under the 2023 Dog Law update, is designed to prevent the spread of disease into established kennel populations.
Inspections and Recordkeeping Requirements in Pennsylvania
The Bureau of Dog Law Enforcement conducts inspections of licensed kennels. New facilities must pass an inspection before getting a license. After that, regular inspections make sure you follow all the rules for housing, sanitation, veterinary care, and animal welfare.
Inspectors check for adequate space, clean water, proper food, and safe living conditions for all dogs. Inspections are unannounced, meaning you must maintain compliance at all times — not just when you know an inspector is coming.
The state’s inspection program is substantial in scale. As of December 2024, the Pennsylvania Department of Agriculture reported enforcing health and safety regulations and upholding Pennsylvania’s high standards for conditions in kennels by licensing 2,890 operations and conducting more than 5,656 inspections.
Recordkeeping is a separate mandatory obligation. Every keeper of a kennel shall keep, for two years, a record of each dog at any time kept in the kennel. Such record shall show: the breed, color, markings, sex, and age of each dog; the date on which each dog entered the kennel; and the full name and physical address at the time the dogs were received of the previous owner or kennel from whom the dog was received.
Records must also capture what happens to each dog when it leaves. Records must show how the dog is dispensed. If the dog was transferred to another person or kennel, the record must state the full name and physical address of the person or kennel to whom the dog was dispensed.
- Breed, color, markings, sex, and age of each dog
- Date the dog entered the kennel
- Full name and physical address of the previous owner or source kennel
- Purpose for which the dog is kept
- How the dog was dispensed (sold, transferred, given away, deceased)
- Full name and physical address of the person or kennel receiving the dog
- Vaccination and health documentation
All records must be available for inspection by the Bureau of Dog Law Enforcement at any time. Keeping organized, up-to-date records is not just good practice — it is a legal requirement with real enforcement consequences.
Common Mistake: Some breeders keep sale records but neglect to document dogs that died or were transferred to another kennel. Pennsylvania law requires you to record the disposition of every dog that enters your facility, regardless of how it left.
Kennels that sell at retail must also include their kennel license number in any advertisement for dogs offered for sale or adoption. This transparency requirement, enacted under the 2023 Dog Law amendments, applies to both print and online listings.
Federal Breeder Requirements That Apply in Pennsylvania
State licensing does not exempt you from federal oversight. Depending on how you sell dogs, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) may also regulate your operation under the federal Animal Welfare Act (AWA).
The Animal Welfare Act sets standards of care and treatment for dogs used in research, exhibited to the public, bred for commercial sale, or transported in commerce. These standards include specific requirements for the amount of space primary enclosures must provide.
You may also need a federal license if you have more than 4 breeding females and sell dogs sight-unseen. The key trigger for USDA licensing is whether the buyer, seller, and dog are all present at the time of the transaction.
- You need a USDA license if you have 5 or more female dogs.
- A USDA license is required to ship a puppy, which includes any transaction where the breeder, retail buyer, and puppy are not present at the time of purchase.
- Selling puppies to any wholesale buyer or dealer requires a USDA license.
All USDA/APHIS-licensed breeders must comply with the standards of care outlined in federal regulations (9 CFR §§ 2.40 and 3.1–3.19). These standards set minimum requirements for humane handling, shelter, space requirements, feeding, watering, sanitation, ventilation, veterinary care, and transport, among other things.
Pennsylvania’s own standards are generally more stringent than the federal minimums. States have the authority to impose higher standards of care than those required under the AWA. At least 19 states have specified standards of care for commercial breeders or large kennel operators in state law and regulations. These state requirements generally apply to more breeders than the AWA and establish more stringent standards of care than the AWA requires. This means that if you are USDA-licensed in Pennsylvania, you still must meet — and in most cases exceed — the federal floor by complying with state law.
The USDA pre-license inspection process has its own timeline. You must be fully compliant in order to pass a pre-license inspection and receive a license. You can receive up to 3 pre-license inspections within a period not to exceed 60 days from the day of the first pre-license inspection to correct any deficiencies. If you do not pass inspection within the 60-day period, you must wait at least 6 months before reapplying for a license.
If you breed or own other animals alongside your dogs, you may also want to review Pennsylvania’s broader animal ownership regulations. Our guides on goat ownership laws in Pennsylvania and beekeeping laws in Pennsylvania cover how the state regulates other common farm and hobby animals.
Penalties for Violating Dog Breeding Laws in Pennsylvania
Pennsylvania significantly increased its penalty structure when the 2023 Dog Law amendments took effect. The updated fines apply to unlicensed operations, welfare violations, and a range of other infractions.
Fines for unlicensed dogs range from $100 to $500, plus court costs. The criminal penalties for all other violations of the dog law have increased to $500 to $1,000 for summary offenses and $1,000 to $5,000 for misdemeanor offenses plus court costs.
| Violation Type | Penalty Range | Classification |
|---|---|---|
| Unlicensed individual dog | $100–$500 + court costs | Summary offense |
| Other Dog Law violations (summary) | $500–$1,000 + court costs | Summary offense |
| Other Dog Law violations (misdemeanor) | $1,000–$5,000 + court costs | Misdemeanor offense |
| Harboring a dangerous dog (annual registration) | $1,000 per year | Registration fee |
Operating a kennel without a license is a violation of the Pennsylvania Dog Law. Penalties can include fines, license suspension, or license revocation. Late registration results in additional penalty fees.
License revocation carries serious consequences beyond the fine itself. Upon revocation, suspension, or denial of a kennel license, the Department may seize and impound any dog in the possession, custody, or care of the person whose license is revoked, suspended, or denied if there are reasonable grounds to believe that the dog’s health, safety, or welfare is endangered. The person from whom the dog was seized and impounded shall pay for reasonable costs of transportation, care, and feeding of the dog.
Prior animal cruelty convictions also affect your ability to obtain a license at all. The Secretary will not issue a kennel license or out-of-State dealer license to a person who has been convicted of a violation of 18 Pa.C.S. § 5511 within the last 10 years. A cruelty conviction can permanently close the door on legal kennel operation in Pennsylvania.
Important Note: Misdemeanor charges under the Dog Law can carry jail time in addition to fines. If your operation is facing a misdemeanor-level violation, consulting with a qualified attorney is strongly recommended before responding to enforcement actions.
Enforcement is active and ongoing. Pennsylvania’s Bureau of Dog Law Enforcement employs state dog wardens who conduct unannounced inspections and investigate complaints. The 2023 law update added more dog wardens to communities across the state, increasing the likelihood that violations will be detected and acted upon.
Understanding how Pennsylvania’s dog laws interact with broader ownership and liability rules can help you stay fully compliant. Our resources on dog bite laws in Pennsylvania and barking dog laws in Pennsylvania cover additional areas where breeders and kennel operators may face legal exposure. For a broader look at how animal regulations work across the country, see our guide to United States laws on exotic pets.
Pennsylvania’s dog breeding laws are detailed, actively enforced, and subject to periodic updates. Staying current with the Bureau of Dog Law Enforcement’s guidance — and consulting a licensed attorney when facing enforcement questions — is the most reliable way to protect your operation, your animals, and your livelihood.
