Summary
The Animal Welfare Act (AWA) was first passed in 1966 to prevent pets from
being stolen for sale to research laboratories, and to improve the treatment and well-
being of animals intended for research. Passage in 2007 of legislation (H.R. 137; P.L.
110-22) on animal fighting marked the sixth time that Congress has amended the act to
strengthen enforcement, expand coverage to more animals and activities, or curtail
practices viewed as cruel, among other things. AWA amendments in the 2008 farm bill
(P.L. 110-246) ban the importation of puppies under six months of age for resale, tighten
prohibitions on dog and other animal fighting activities, and increase penalties for
violation of the act. Other AWA bills in the 110th Congress included H.R. 1280/S. 714,
H.R. 1947, H.R. 2193, H.R. 3219, H.R. 3327, S. 1880, and H.R. 6949/S. 3519.
The Animal Welfare Act (AWA; 7 U.S.C. 2131 et seq.) is intended to ensure the
humane treatment of animals that are intended for research, bred for commercial sale,
exhibited to the public, or commercially transported. Under the AWA, businesses and
others with animals covered by the law must be licensed or registered, and they must
adhere to minimum standards of care. Farm animals are among those not covered by the
act, which nonetheless provides a broad set of statutory protections for animals.1
The law was first passed in 1966 following several years of lobbying by animal
welfare organizations and growing public outcry over allegations that large numbers of
pets were being “dognapped” for sale to medical research laboratories. Congress
amended the original law in 1970, 1976, 1985, 1990, and 2002. These amendments
generally were intended to expand the scope of the AWA or to clarify various provisions.
The U.S. Department of Agriculture’s (USDA’s) Animal and Plant Health Inspection
1 Numerous other federal laws seek to protect other classes of animals, often those from the wild.
Examples include the Marine Mammal Protection Act, the Lacey Act as amended, and the Wild
Free-Roaming Horses and Burros Act. These and the others are described, with legal citations,

Service (APHIS) administers the AWA. The House and Senate Agriculture Committees
have exercised primary legislative jurisdiction over the act and its amendments.
Key Provisions2
Animals Covered. The act applies to any live or dead dog, cat, nonhuman
primate, guinea pig, hamster, rabbit, or other warmblooded animal determined by the
Secretary of Agriculture to be for research or exhibition, or used as a pet. The AWA
explicitly excludes birds, rats, and mice bred for research; horses not used for research;
and other farm animals used in the production of food and fiber.3 Animals sold in retail
facilities are not covered, unless they are wild or exotic animals. Cold-blooded animals
like fish and reptiles also are excluded from coverage.
Businesses and Activities Covered. Generally, animal dealers and exhibitors
must obtain a license, for which an annual fee is charged. APHIS does not issue a license
until it inspects the facility and finds it to be in full compliance with its regulations. If a
facility loses its license, it cannot continue its regulated activity. Those who conduct
research, and general carriers that transport regulated animals, do not need a license but
must still register with APHIS and undergo periodic inspections. Specific details follow.
Dealers, including pet and laboratory animal breeders and brokers, auction operators,
and anyone who sells exotic or wild animals, or dead animals or their parts, must have an
APHIS license for that activity. So-called Class A licensees are breeders who deal only
in animals they breed and raise; all others are called Class B licensees. Exempt from the
law and regulations are retail pet stores, those who sell pets directly to pet owners, hobby
breeders, animal shelters, and boarding kennels.
Exhibitors must be licensed by APHIS as such. These so-called Class C licensees
include zoos, marine mammal shows, circuses, carnivals, and promotional and
educational exhibits. The law and regulations exempt agricultural shows and fairs, horse
shows, rodeos, pet shows, game preserves, hunting events, and private collectors who do
not exhibit, among others.
Animal transporters must be registered, including general carriers (e.g., airlines,
railroads, and truckers). Businesses that contract to transport animals for compensation
are considered dealers and must have licenses.
Research facilities must be registered. They include state and local government-run
research institutions, drug firms, universities, diagnostic laboratories, and facilities that
study marine mammals. Federal facilities, elementary and secondary schools, and
agricultural research institutions are among those exempt from registration.
Animal fighting generally is prohibited by the AWA. The ban includes dogfights
and bear and raccoon baiting; sponsors and exhibitors are subject to penalties. The AWA
also has banned bird fights, except in the states where they are not prohibited by state law

(namely Louisiana and New Mexico), and the sponsor or exhibitor was unaware that the
transaction had occurred in interstate commerce.

Standards. All licensed and registered entities must comply with USDA-APHIS
regulations, including recordkeeping and published standards of care. These standards
deal with humane handling, shelter, space requirements, feeding, watering, sanitation,
ventilation, veterinary care, and transport. (AWA regulations are at 9 C.F.R. §1.1 et seq.)
Oversight and Enforcement
APHIS’s Animal Care (AC) program oversees the AWA, under which approximately
10,300 facilities were licensed or registered in FY2008. That year, AC had total staff of
approximately 200 and an annual budget of nearly $21 million.4
AC officials make unannounced inspections of registered and licensed facilities to
ensure compliance with all rules. Under the AWA, research facilities are to be inspected
at least annually. Inspection frequency for other AWA-regulated facilities is based on
risk; for example, moderate-risk facilities are to be visited about once yearly. APHIS
inspectors also conduct searches to identify unlicensed or unregistered facilities. Failure
to correct deficiencies can result in confiscation of animals, fines, cease-and-desist orders,
or license suspensions. AC inspectors conducted 18,343 inspections during FY2007,
which included pre-licensing as well as compliance inspections, according to APHIS.
Legislative History
Original Law. Although long known as the Animal Welfare Act, the original law
was passed simply as P.L. 89-544, the Act of August 24, 1966. The law requires dealers
in dogs and cats for research purposes to obtain a USDA license and to abide by USDA-
set humane treatment requirements. It also requires a research facility to register with
USDA only if it uses dogs or cats and either (1) purchases them in interstate commerce
or (2) receives federal research money. The law authorizes the Secretary of Agriculture
to set humane handling standards for guinea pigs, nonhuman primates, rabbits and
hamsters as well as dogs and cats — but only dealers and research facilities with dogs and
cats are subject to these standards. Farmers and pet owners are among those exempted
from the law. Other provisions spell out recordkeeping requirements, enforcement
authorities and penalties for noncompliance.
Animal Welfare Act of 1970. P.L. 91-579 expands animal coverage to include
all warm-blooded animals determined by the Secretary to be used for experimentation or
exhibition, except horses not used in research and farm animals used in food and fiber
research. The 1970 law also incorporates exhibitors; defines research facilities; and
exempts from coverage retail pet stores, agricultural fairs, rodeos, dog and cat shows.
Animal Welfare Act Amendments of 1976. P.L. 94-279 was passed mainly
to clarify and expand previous regulations covering animal transport and commerce. This
4 A portion of this amount, nearly $500,000, was used to administer the Horse Protection Act (15
U.S.C. §§1821-1831), which makes it a crime to exhibit or transport any “sore” horse, i.e. one
whose feet have been injured to alter its gait.

CRS-4
act for the first time addresses animal fighting, making it illegal to exhibit or transport
interstate animals used in fighting ventures, such as dogs and roosters. Hunting animals
are generally exempt, as are live fighting birds for states where such fighting is legal.
Improved Standards for Laboratory Animals Act. These amendments were
passed as Title XVII, Subtitle F of the Food Security Act of 1985 (P.L. 99-198, the
omnibus 1985 farm bill). The law directs the Secretary to set new minimum standards
of care for handling, housing, feeding, water, sanitation, ventilation, and so forth. One
new provision that was highly contentious at the time singles out two species by requiring
standards for the exercise of dogs and the psychological well-being of primates. The law
provides that research facilities must have procedures that minimize pain and stress to the
animals, and describes practices considered to be painful. Each research facility must
establish an Institutional Animal Care and Use Committee to review research proposals
that involve animal experimentation and to provide oversight of laboratories. The
amendments also increase civil and criminal penalties for AWA violations, and establish
an animal welfare information center at USDA’s National Agricultural Library.
Protection of Pets. Section 2503 of the Food Agriculture, Conservation, and
Trade Act of 1990 (P.L. 101-624, the 1990 farm bill) extends pet protections. It requires
public and private animal shelters and research facilities which acquire dogs and cats to
hold them for at least five days to allow time for either adoption or recovery by the
original owner before they can be sold to a dealer. Dealers are prohibited from selling
dogs and cats they did not breed unless they provide certified records on, among other
things, the animals’ origin. Other new recordkeeping requirements also are specified.
2002 Amendments. Title X, Subtitle D of the Farm Security and Rural
Investment Act of 2002 (P.L. 107-171, the omnibus 2002 farm bill) makes it a
misdemeanor to ship a bird in interstate commerce for fighting purposes, or to sponsor or
exhibit any bird in a fight with knowledge that any of the birds were so shipped (even
fights within a state where the practice is permitted). The law also increases the
maximum financial penalty for a violation (a misdemeanor) of the anti-fighting provisions
of the AWA, to $15,000 from $5,000. The 2002 law also explicitly excludes from AWA
coverage birds, rats, and mice bred for research purposes. The Secretary of Agriculture
had previously published regulations excluding these animals from coverage, which the
Animal Legal Defense Fund challenged in federal court. When USDA agreed to settle
the case by essentially reversing its regulations, Congress (in P.L. 106-387, the FY2001
agriculture appropriation) blocked the action by prohibiting funds for such a rule change.
The 2002 law made the exclusion a permanent part of the AWA.5
Animal Fighting Prohibition Enforcement Act of 2007. P.L. 110-22, signed
into law May 3, 2007, makes a violation of the animal fighting provisions of the AWA
a felony punishable by up to three years in prison, under Title 18 of the U.S. Code (Crimes
and Criminal Procedure). The law, based on companion bills introduced by
Representative Gallegly (H.R. 137) and Senator Cantwell (S. 261), also makes it a felony
to trade, in interstate and foreign commerce, knives, gaffs, or other sharp objects designed
for use in animal fighting, or to use the Postal Service or other “interstate instrumentality
to trade in such devices, or to promote an animal fighting venture.”

CRS-5
Proponents of various animal fighting bills had observed that in 2001, the House and
Senate had approved strong animal fighting sanctions in their respective farm bills, but
that conferees on the final 2002 farm bill (P.L. 107-171) removed the felony language.
Stronger deterrents are needed because animal fighting is a brutal, inhumane practice that
is closely associated with criminal activity, endangers children where aggressive dogs are
being reared, and may contribute to the spread of avian influenza in the case of live birds,
they argued. Opponents have countered that such measures would violate provisions in
the U.S. Constitution that protect states’ rights, including the Commerce Clause, and that
recognize private citizens’ right to travel for economic reasons. Completely banning
and/or stiffening penalties for all animal fighting activities would drive them further
underground, undermining efforts to protect animals and the public from any disease
problems created by such activities, other opponents have argued.
2007-2008 Farm Bill
Animal Fighting. A new omnibus farm bill (P.L. 110-246, first passed as H.R.
2419) contains a number of amendments to the AWA. One section (§14207) would
strengthen further the definitions of, and penalties for, activities related to animal fighting.
For example, maximum imprisonment would rise to five years from the current three
years. The animal fighting provision is based on language in S. 1880 and H.R. 3219 —
bills introduced shortly after the July 17, 2007, indictment of NFL quarterback Michael
Vick on charges related to dog fighting — to more explicitly ban various dog fighting
activities, and to define the term.6
Puppy Imports; Penalties for AWA Violations. The 2008 farm bill requires
regulations to prohibit imports for resale of dogs unless they are at least six months of
age, in good health, and have all necessary vaccinations, with exemptions for research,
veterinary treatment, or imports into Hawaii from certain countries. Another section
(§14214) would increase the maximum penalty for a general violation of the act from the
current $2,500 to $10,000 for each violation.
Dogs and Cats in Research. Both the House- and Senate-passed versions of
the omnibus farm bill had contained the language of two other pending bills (H.R. 1280;
S. 714) to restrict where research facilities could obtain their dogs and cats. Such animals
were to be obtained only from licensed breeders, publicly operated shelters, other licensed
research facilities, or donees that had bred and raised the animal or that had owned it for
at least the previous year. Additional language in the Senate but not the House bill
directed USDA to phase out the use of random source dogs and cats from “Class B”
dealers within five years. However, all of these provisions were deleted by farm bill
conferees. The final version instead directs USDA to review “any independent reviews
by a nationally recognized panel of experts” on Class B use by researchers.
Conferees said in accompanying report language that they were aware of concerns
regarding use of random source animals from Class B dealers. However, they observed
that USDA’s FY2008 appropriation (part of the Consolidated Appropriations Act, 2008,
6 Another pending bill (H.R. 3327) includes the provisions of H.R. 3219 and S. 1880, as well as
language to enable animal humane agencies to initiate civil actions where violations are alleged.

CRS-6
P.L. 110-161) had requested such an independent review, which the National Academies
of Science is undertaking. The results, expected in spring 2009, “will help provide
Congress information regarding the value of Class B dogs and cats in medical research.”
Critics have asserted that the 15 Class B dealers who still collect dogs and cats from
random sources, including “free to a good home” classified ads, auctions, and flea
markets, are more concerned about profit than animal welfare. Others contend that
passage would leave no viable sources of random source dogs and cats, which are needed
by medical and veterinary researchers because of their genetic and age diversity; and that
the majority of Class B dealers are in compliance with the AWA.
Other Selected Bills
Animal Protection Accountability Improvement Act. H.R. 2193 would
amend the AWA to prohibit the use of animals in marketing medical devices and
products, and increase the penalties for animal research facilities that violate this part of
the act. This language was the House farm bill (H.R. 2419) but was deleted by conferees.
Interest in the proposal was stimulated at least in part by a sales demonstration in an Ohio
medical facility, where a dog reportedly was given a brain aneurysm, repeatedly subjected
to the medical device, and later put down. Proponents believe the incident highlighted
an inhumane practice done for profit, not science or medicine. Opponents argue that the
facility had not approved the demonstration and acted swiftly to address it, and that most
research facilities even go beyond federal welfare requirements to ensure that research
animals do not experience pain and suffering.
Haley’s Act. This bill (H.R. 1947) would amend the AWA to make it unlawful for
animal exhibitors and dealers (but not accredited zoos) to allow direct contact between
the public and big cats such as lions and tigers. The bill, which also would increase
penalties for AWA violations, was named for a teenager killed by a grown Siberian tiger
in 2005 while having her picture taken with it at an APHIS-licensed facility. Opponents
argue that the measure is unnecessary because federal regulations already ban such
contacts with older cats (the facility presumably was out of compliance) and because zoos
will gain a monopoly in exhibiting younger cats.
Puppy Mills. The proposed Puppy Uniform Protection and Safety (PUPS) Act
(H.R. 6949/S. 3519) would require those who breed dogs to obtain an AWA license from
USDA if they raise more than 50 dogs in a 12-month period and sell directly to the public.
The bills also would set some minimum daily exercise requirements for dogs held by the
dealers. Supporters of the bills contend that the Internet and other relatively recent
marketing techniques have enabled importers and large commercial breeders, whom they
call “puppy mills,” to sell their animals directly to the public while evading the AWA
licensing and humane handling requirements, even though they are selling large numbers
of animals. (Wholesale breeders are already covered by the AWA.) Opponents counter
that the measures would strain USDA resources and newly subject thousands of relatively
small in-home and hobby breeders, as well as rescue organizations, to burdensome
licensing and regulatory requirements that were designed for large commercial businesses.
The bills are similar in intent to measures offered in the 109th Congress, the Pet Animal
Welfare Statute (“PAWS”; H.R. 2669; S. 1139). These bills would have required
commercial dog and cat breeders to obtain AWA licenses if they sold more than six litters
or more than 25 dogs or cats directly to the public each year, among other things.
