PlainBill explanation
Based on the full Introduced in House · 2026-09-21 text. This explanation has not received human editorial review. This overview describes the proposal’s major provisions; it does not establish what its real-world effects would be.
This bill would prohibit, in or affecting commerce, breeding dogs for research and distributing them commercially for research. It would also prohibit acquiring, receiving, or using dogs for research when a person knows, or has reason to know, they were bred for that purpose. Violations could bring financial penalties and would require license or registration suspension or revocation. People holding research-bred dogs at enactment would have to offer them for adoption.
It shall be unlawful for any person, in or affecting commerce— (1) to breed a dog for research purposes; (2) to engage in commercial distribution of a dog for research purposes; (3) to acquire, receive, or use for research purposes a dog that such person knows, or has reason to know, was bred for such purposes;
shall suspend or revoke the license or registration of any person that violates subsection (a).
Any person that violates subsection (a) may be assessed a civil penalty by the Secretary of not more than $10,000 for each dog with respect to which such violation occurs.
A person who, as of the date of the enactment of this section, is in possession of a dog that was bred for research purposes— (1) may not euthanize such dog on the basis of the enactment of this section; and (2) shall offer such dog for adoption to an individual or to an animal rescue organization (as specified by the Secretary).
Section 1 names the proposal the Prohibiting Unethical Procedures on Pets in Science Act, or PUPPS Act.
This Act may be cited as the Prohibiting Unethical Procedures on Pets in Science Act or the PUPPS Act.
Section 2 would add prohibitions to the Animal Welfare Act covering conduct in or affecting commerce. Attempts to breed dogs for research or distribute them commercially for research would also be prohibited. The attempt prohibition would also cover acquiring, receiving, or using a dog for research purposes when the person knows, or has reason to know, the dog was bred for research.
The Animal Welfare Act (7 U.S.C. 2131 et seq.) is amended by adding at the end the following: 30. Prohibition on breeding of dogs for research (a) Prohibition It shall be unlawful for any person, in or affecting commerce— (1) to breed a dog for research purposes; (2) to engage in commercial distribution of a dog for research purposes; (3) to acquire, receive, or use for research purposes a dog that such person knows, or has reason to know, was bred for such purposes; or (4) to attempt to take any action specified in paragraphs (1) through (3).
The breeding restriction would cover intentional mating, reproduction, insemination, and embryo implantation. It would also cover keeping a dog for breeding for research use or with the purpose of supplying its offspring for research.
The term breed means, with respect to a dog, the intentional mating, reproduction (or causing the reproduction), or insemination of dogs, or implanting embryos in dogs.
The term breed a dog for research purposes means to breed a dog, or to maintain a dog for the purpose of breeding, for use, or with the purpose that any offspring be sold, leased, transferred, maintained, or otherwise provided for research purposes.
Commercial distribution would extend beyond sales. It would include advertising, arranging transactions, transport, imports, exports, leases, transfers, and otherwise providing a dog in commerce to a research facility, dealer, or another person.
The term commercial distribution means, with respect to a dog, the selling, purchasing, offering for sale, advertising, brokering, transporting, shipping, importing, exporting, leasing, transferring, donating for consideration, delivering, or otherwise providing such dog in commerce to a research facility, dealer, or other person.
The proposal would cover live domestic dogs. Research purposes would include scientific and medical research, pharmaceutical research, testing involving toxic substances, product development, regulatory testing, contract research, and experimentation.
The term dog means any live member of the species Canis lupus familiaris.
The term research purposes means any scientific, biomedical, pharmaceutical, toxicological, product development, regulatory testing, contract research, or experimentation.
The Secretary would be barred from issuing or renewing a license under section 3, or accepting a registration under section 6, that authorizes prohibited activities. The Secretary would have to suspend or revoke the license or registration of anyone violating the prohibitions.
The Secretary may not issue or renew a license under section 3, or accept a registration under section 6, that authorizes an activity prohibited under subsection (a), and shall suspend or revoke the license or registration of any person that violates subsection (a).
The Secretary could impose civil financial penalties of up to $10,000 per dog, or up to $40,000 per dog for repeated violations. These are maximum amounts, not mandatory penalties.
Any person that violates subsection (a) may be assessed a civil penalty by the Secretary of not more than $10,000 for each dog with respect to which such violation occurs.
In the case of a repeated violation of subsection (a) by a person, such person may be assessed a civil penalty of not more than $40,000 for each dog with respect to which such violation occurs.
Each dog would count as a separate offense, but a continuing violation involving the same dog would count only once. Total civil penalties under this subsection arising from a single inspection, investigation, or complaint could not exceed $500,000. Penalty decisions would have to consider business size, the severity of the violation, and previous violations of this section.
Each dog with respect to which a violation of subsection (a) occurs shall constitute a separate offense. A continuing violation with respect to the same dog shall not constitute more than one offense.
The Secretary may not assess civil penalties under this subsection in an aggregate amount exceeding $500,000 with respect to violations of this section arising from a single inspection, investigation, or complaint.
the Secretary shall consider the size of the business of the person involved, the severity of the violation, and the history of previous violations of this section by such person.
Anyone possessing a research-bred dog on the enactment date would have to offer it for adoption to an individual or an animal rescue organization specified by the Secretary. They could not euthanize that dog because of the enactment. The text requires an adoption offer, not a completed adoption, and does not prohibit euthanasia on every possible ground.
A person who, as of the date of the enactment of this section, is in possession of a dog that was bred for research purposes— (1) may not euthanize such dog on the basis of the enactment of this section; and (2) shall offer such dog for adoption to an individual or to an animal rescue organization (as specified by the Secretary).
The bill would replace an existing Animal Welfare Act provision with a requirement that the Secretary create a regulatory exception to the referenced requirements when a dog is imported for veterinary treatment. The supplied text does not reproduce those requirements or the exception being replaced.
Section 18(b)(2) of the Animal Welfare Act (7 U.S.C. 2148(b)(2)) is amended by striking subparagraph (A) and inserting the following: (A) Exception The Secretary, by regulation, shall provide an exception to any requirement under paragraph (1) in any case in which a dog is imported for veterinary treatment.
The Secretary of Agriculture would have to issue or revise implementing regulations within 180 days after enactment. The amendments would apply starting 180 days after enactment; the adoption provision uses possession on the enactment date to identify affected dog holders.
Not later than 180 days after the date of enactment of this section, the Secretary of Agriculture shall issue regulations, or revise such regulations as may be necessary, to carry out the amendments made by this section.
The amendments made by this section apply beginning on the date that is 180 days after the date of enactment of this Act.
A person who, as of the date of the enactment of this section, is in possession of a dog that was bred for research purposes

Findings to examine
The finding identifies a purpose-specific exemption warranting scrutiny. Classification does not imply improper purpose.
People importing dogs for veterinary treatment would receive an exception, established by regulation, from the requirements referenced in section 18(b)(1). This is a purpose-specific exemption within the bill's changes to dog-related rules. The existing requirements and prior exception are not supplied, so the text does not establish whether this treatment is new, retained, or narrowed.
Section 18(b)(2) of the Animal Welfare Act (7 U.S.C. 2148(b)(2)) is amended by striking subparagraph (A) and inserting the following: (A) Exception The Secretary, by regulation, shall provide an exception to any requirement under paragraph (1) in any case in which a dog is imported for veterinary treatment.
