Hawaii is known for some of the strictest animal import rules in the country, yet when it comes to large-scale commercial dog breeding, the state has historically left a significant gap in its legal framework. Hawaii has no laws that regulate pet stores or breeders in the dedicated way that many other states do — meaning the oversight net that catches puppy mill operators elsewhere simply does not exist here in the same form.
That does not mean anything goes. Hawaii’s general animal cruelty statutes still apply, and federal law reaches certain breeders regardless of state lines. Legislators have also been actively pushing to change the status quo, most recently through Senate Bill 593 in the 2025 session. If you are a concerned consumer, a dog owner, or someone who wants to report a suspected operation, understanding exactly where the law stands — and where it falls short — is the first step.
This article walks through each layer of Hawaii’s legal landscape for commercial dog breeding, from how the state defines a puppy mill to what penalties can apply when the law is broken. You can also compare Hawaii’s approach with puppy mill laws in California or puppy mill laws in Colorado, two states with more developed regulatory frameworks.
What Is Considered a Puppy Mill in Hawaii
Hawaii does not have a statutory definition of “puppy mill” written into state law. The term is a colloquial one used by animal welfare advocates and legislators alike to describe a specific type of operation. Commercial breeders may sometimes operate under conditions that justify calling their operation a “puppy mill” — a breeding environment in which puppies, bred primarily in pursuit of profit, are cared for only minimally.
In practical terms, a puppy mill is characterized by overcrowded or unsanitary housing, minimal veterinary care, continuous breeding of females without adequate recovery time, and the prioritization of volume over the health of individual animals. Animals sold in pet stores are often obtained from unregulated commercial breeders who do not provide sanitary and humane living conditions. Many of the puppies sold in pet stores are obtained from mass breeding operations known as puppy mills, and in Hawaii, these puppy mills are often hidden from public view on lands designated for agricultural use and exempt from a law that limits dog ownership to a maximum of ten dogs.
Hawaii’s household dog limit is ten animals, but agricultural land classifications have historically created a loophole. By law, households are allowed up to ten dogs, but a farm can essentially have an unlimited number of dogs — and right now there are no state laws that specifically regulate large-scale breeders. This gap is precisely what recent legislative efforts have aimed to close.
Key Insight: If you are buying a puppy in Hawaii, ask the seller directly how many intact adult dogs they keep and how many litters they produce per year. A reluctance to answer those questions is a meaningful warning sign.
Federal Law and How It Applies in Hawaii
Under federal law, the Animal Welfare Act (AWA) is the only law that governs the humane treatment of animals bred for purposes of sale. The AWA is administered by the USDA’s Animal and Plant Health Inspection Service (APHIS), which licenses and inspects breeders who sell animals wholesale — typically to pet stores or brokers — rather than directly to the public.
The Animal Welfare Act does set minimum welfare standards for dogs in puppy mills, but these standards are extremely inadequate, and there is a massive regulatory loophole which exempts from federal oversight any commercial dog breeders who sell directly to the public, including over the Internet. This loophole is especially relevant in Hawaii, where the direct-sale model is common.
Breeders that sell their animals sight unseen are licensed and inspected by the USDA, but facilities on the local level are governed by a patchwork of state laws that vary widely in their licensing, inspections, and enforcement. Because Hawaii has no dedicated state-level commercial breeder law, any breeder selling directly to buyers — including at local swap meets — falls entirely outside both federal and state regulatory reach.
Infrequent investigations and inadequate enforcement by APHIS have allowed many commercial breeders to continue operating despite falling below even the minimum federal standards. While APHIS is authorized to carry out various enforcement actions, including revoking USDA licenses, the USDA’s own Inspector General found that APHIS was assessing only minimal penalties against offenders. For Hawaii residents, this means federal oversight — even where it technically applies — offers limited practical protection. You can review how other states handle this gap by reading about puppy mill laws in New York or puppy mill laws in Pennsylvania.
Does Hawaii Have Puppy Mill Laws
Hawaii does not have a dedicated puppy mill statute. Some states have no discussion of breeding regulations in their statutes at all, and Hawaii is among them — placing it in a category with states like Alaska, Arkansas, and Mississippi that have not enacted specific commercial breeder laws.
With animal shelters in Hawaii constantly overcapacity, Senate Bill 593 aims to control dog overpopulation, and the Hawaiian Humane Society says it is long overdue. The bill was introduced in the 2025 legislative session and advanced from committee with amendments. Senate Bill 593 seeks to regulate commercial dog breeders by establishing a definition for what constitutes a dog breeder in Hawaii, sets a statewide limit law for intact dogs, and establishes standards of care.
As of the time of publication, SB 593 had cleared a Senate committee hearing but had not been confirmed as enacted into law. You should verify its current status directly with the Hawaii State Legislature before relying on it as binding law. The enforcement question also remains open: concerns were raised that the bill would not prevent puppy mills from operating because enforcement is deferred to the counties with no funding attached, leaving counties unable to stand up enforcement without additional resources.
Important Note: Because SB 593’s final passage and effective date were not confirmed in available sources as of June 2026, the sections below describe Hawaii’s legal landscape as it has historically stood, with notes on what the proposed bill would change if enacted.
Commercial Breeder Licensing and Inspection Requirements in Hawaii
Hawaii is among the states that require no license to breed dogs. There is no state-administered licensing system, no mandatory inspection regime, and no minimum standards of care that a commercial breeder must meet under Hawaiian law as a condition of operating. This distinguishes Hawaii from states like Missouri, Ohio, and Michigan, which require breeders to be licensed and regularly inspected.
Senate Bill 593 proposed changing this by creating a threshold-based definition of a commercial breeder. Under the amended bill, a “dog breeder” would be defined as someone who owns, possesses, controls, or otherwise has custody of more than ten dogs over the age of twelve months with intact sexual organs, AND who sells, barters, or otherwise transfers more than three litters AND more than twenty-five dogs per calendar year — and all criteria must be met for the bill to apply.
The bill also contains a statewide ownership limit of 30 intact dogs over one year of age. In addition, the bill allows for each county to assess its individual situations regarding licensing and enforcement, which means implementation could vary across Oahu, Maui, Hawaii Island, and Kauai even if the bill passes.
| Requirement | Current Hawaii Law | Proposed Under SB 593 |
|---|---|---|
| State breeder license | Not required | Required for breeders meeting threshold |
| Mandatory inspections | None | County-level enforcement proposed |
| Intact dog ownership cap | 10 dogs (residential); unlimited on agricultural land | 30 intact dogs statewide |
| Standards of care | General cruelty statutes only | Specific standards for licensed breeders |
For context on how a fully developed licensing system works, see puppy mill laws in Illinois or puppy mill laws in Wisconsin.
Pet Store Sale Restrictions in Hawaii
Hawaii does not currently have a statewide law prohibiting pet stores from selling puppies sourced from commercial breeders or puppy mills. States that have prohibited the retail sale of puppies and kittens in pet stores include California (2017), Maryland (2018), Maine (2019), Washington (2021), Illinois (2021), New York (2022), Oregon (2023), and Vermont (2024) — but Hawaii is not among them.
Hawaii House Bill 849, introduced in 2024, proposed requiring pet stores to source dogs, cats, and rabbits only from shelters, rescues, or certain approved entities. Under that bill, each pet store operator would be required to maintain records documenting the source of each animal for at least one year, and to post a sign in a conspicuous location on the cage or enclosure displaying the name and address of the source from which the animal was obtained.
That bill also proposed a civil penalty structure: a pet store operator that violates the section would be subject to a civil penalty of $500, and each animal offered for sale in violation of the section would constitute a separate offense. As with SB 593, you should confirm the current status of HB 849 with the Hawaii legislature, as its passage was not confirmed in available sources.
Pro Tip: When purchasing a puppy from a Hawaii pet store, ask the store for the breeder’s name, address, and any available health records. Reputable stores should have this information on hand. If they cannot or will not provide it, consider that a red flag and explore adoption through the Hawaiian Humane Society instead.
If you want to compare Hawaii’s approach to states that have enacted full retail bans, puppy mill laws in Washington and California’s framework offer useful points of reference.
How to Report a Suspected Puppy Mill in Hawaii
Even without a dedicated puppy mill statute, you have several avenues for reporting suspected inhumane breeding operations in Hawaii. The most direct path is through your county’s humane society or animal control agency, which has authority to investigate animal cruelty complaints under Hawaii Revised Statutes Chapter 711.
- Hawaiian Humane Society (Oahu): The Hawaiian Humane Society serves as the primary animal control agency for the City and County of Honolulu. Local, state, and federal laws all protect animals and people in the community, and enforcement is determined by jurisdiction and may involve the Hawaiian Humane Society, the Honolulu Police Department, or other agencies. You can reach their animal cruelty investigation unit directly through their website at hawaiianhumane.org.
- Neighbor island counties: On Maui, Hawaii Island, and Kauai, contact your county’s Department of Water Supply or Department of Environmental Management animal control division. Each county operates its own animal control services.
- USDA APHIS: If the suspected breeder sells animals to pet stores or over the internet without meeting buyers in person, they may be subject to federal oversight. You can file a complaint with USDA APHIS Animal Welfare directly.
- Hawaii Department of Agriculture: The Animal Industry Division of the Hawaii Department of Agriculture handles domesticated animal concerns and may be a relevant contact depending on the nature of the operation.
Under Act 239, Session Laws 2006, law enforcement officers are authorized to enter premises and impound a pet animal when there is probable cause to believe the pet animal is being subjected to cruel treatment. This means that if you provide credible information to animal control or law enforcement, they have legal authority to act — even in the absence of a specific puppy mill statute.
Document everything you observe before making a report: dates, locations, the approximate number of animals, and any visible signs of neglect or injury. Photographs or video, if legally obtained, can significantly strengthen an investigation. You can also compare reporting procedures in other states, such as Virginia or Georgia, where dedicated breeder laws give investigators more tools.
Penalties for Puppy Mill Violations in Hawaii
Because Hawaii lacks a dedicated commercial breeder law, penalties for puppy mill-type conduct are rooted in the state’s general animal cruelty statutes under Hawaii Revised Statutes Chapter 711. These statutes can still carry meaningful consequences when violations are serious enough.
Under Hawaii law, a person commits the misdemeanor offense of cruelty to animals if the person intentionally, knowingly, or recklessly overdrives, overloads, tortures, torments, cruelly beats or starves any animal, deprives a pet animal of necessary sustenance, mutilates, poisons, or kills without need any animal other than insects, vermin, or other pests, or engages in animal fighting enterprises.
The severity of the charge scales with the number of animals involved. Cruelty to animals in the second degree is a misdemeanor, except that if the offense involves ten or more pet animals in any one instance, then cruelty to animals in the second degree is a class C felony. This escalation is particularly relevant in puppy mill contexts, where large numbers of animals are typically present.
For the most serious conduct, Hawaii law provides additional consequences. A person commits cruelty to animals in the first degree if the person intentionally or knowingly tortures, mutilates, or poisons or causes the torture, mutilation, or poisoning of any pet animal or equine animal resulting in serious bodily injury or death of the pet animal or equine animal. Cruelty to animals in the first degree is a class C felony, and in addition to any fines and imprisonment imposed, any person convicted shall be prohibited from possessing or owning any pet animal or equine animal for a minimum of five years from the date of conviction.
Under Act 239, Session Laws 2006, courts may also order the forfeiture of an impounded pet animal prior to the disposition of a criminal action against the owner. This provision allows animals to be removed from dangerous conditions before a case is fully resolved — an important protection in large-scale neglect situations.
The table below summarizes the penalty tiers that apply to animal cruelty conduct in Hawaii, including scenarios that could arise from puppy mill-style operations.
| Offense | Classification | Key Trigger |
|---|---|---|
| Cruelty to animals in the second degree | Misdemeanor | Neglect, starvation, confinement in cruel manner (fewer than 10 animals) |
| Cruelty to animals in the second degree (aggravated) | Class C felony | Same conduct involving 10 or more pet animals at once |
| Cruelty to animals in the first degree | Class C felony | Intentional torture, mutilation, or poisoning causing serious injury or death |
| Post-conviction animal ownership ban | Mandatory (minimum 5 years) | Conviction for first-degree cruelty |
If Senate Bill 593 is enacted, additional civil and criminal penalties specific to unlicensed commercial breeders would layer on top of these existing cruelty statutes. For a look at how states with fully developed breeder laws structure their penalty systems, see puppy mill laws in Minnesota, puppy mill laws in New Jersey, or puppy mill laws in Tennessee.
Hawaii’s legal landscape around commercial dog breeding is in active transition. The absence of a dedicated puppy mill law does not mean that inhumane breeders operate without any risk of legal consequences — but it does mean that enforcement depends heavily on the general cruelty statutes and the resources available to county-level animal control agencies. Staying informed, reporting suspected violations promptly, and choosing where you get your dog carefully are the most effective tools available to you right now.
