Dog racing is illegal in most states but horse racing is not because greyhound racing had no federal law protecting it, no national regulator to answer welfare criticism with, and nowhere near the economic or political weight horse racing carries. State legislatures and voters concluded that greyhound racing could not be reformed and shut it down; horse racing, backed by federal statutes and a multibillion-dollar footprint, gets tighter rules instead of prohibition. Commercial greyhound racing is now banned in 44 states, with only two operational tracks left in the country, both in West Virginia.
The Welfare Case That Sank Greyhound Racing
What killed the industry was what the public saw. Investigations documented racing dogs confined 20 to 23 hours a day in small stacked metal crates, fed so-called 4-D meat sourced from livestock that was dead, dying, diseased, or disabled before slaughter. That feed led to repeated illness outbreaks at tracks, including Florida incidents where dogs died and dozens fell sick.
The on-track injury record did the rest of the damage. Broken legs, fractured skulls, and sudden cardiac failure during races became regular talking points in legislative hearings. Overbreeding produced thousands of surplus dogs each year, many euthanized once they could no longer compete. Advocacy groups framed these problems as built into the business model rather than the work of a few bad operators, and that framing stuck. Legislators came to see greyhound racing as an activity that couldn’t be cleaned up, only ended.
Horse racing attracts welfare scrutiny too. The Jockey Club recorded 441 horse deaths from roughly 288,500 starts in 2019. But the political response has been to tighten safety rules rather than ban the sport. Horse racing is treated as reformable; greyhound racing was treated as irredeemable.
The Federal Laws Horse Racing Has and Dog Racing Never Got
Horse racing has something greyhound racing never had: an explicit federal statute authorizing and regulating its wagering nationwide. The Interstate Horseracing Act of 1978 declares it federal policy “to regulate interstate commerce with respect to wagering on horseracing, in order to further the horseracing and legal off-track betting industries in the United States.”1Office of the Law Revision Counsel. 15 USC 3001 – Congressional Findings and Policy The language doesn’t just permit the wagering; it makes the industry’s growth a congressional objective.
The statute works through a consent framework for interstate off-track betting. Before an off-track operation can accept wagers on a race held in another state, it needs approval from the host racing association (which must have a written agreement with its horsemen’s group), the host state’s racing commission, and the off-track state’s racing commission.2Office of the Law Revision Counsel. 15 USC 3004 – Regulation of Interstate Off-Track Wagering That system let horse racing capture betting volume from across the country, stabilizing revenue even as in-person attendance declined.
Nothing comparable was ever passed for greyhound racing. Without a statutory framework linking dog tracks into a national wagering network, the industry stayed dependent on local attendance and vulnerable to state-by-state campaigns. When a state banned dog racing, the tracks in that state simply lost their market with no interstate lifeline.
The Horseracing Integrity and Safety Authority
Congress reinforced horse racing’s federal status in 2020 by passing the Horseracing Integrity and Safety Act, which created a national regulatory body. The Horseracing Integrity and Safety Authority develops and enforces uniform rules on racetrack safety, anti-doping, and medication control across thoroughbred racing in the United States, with the Federal Trade Commission reviewing and approving every proposed rule.3Federal Trade Commission. Horseracing Integrity and Safety Authority (HISA) Oversight The racetrack safety program took effect in July 2022, and the anti-doping and medication control rules followed in May 2023.4Office of the Law Revision Counsel. 15 USC 3051 – Definitions
That matters for the gap between the two sports. When critics argue horses are being harmed, the industry can point to a congressionally authorized regulator with FTC oversight and enforceable national standards. Greyhound racing never built anything close, which left it without a credible answer when welfare advocates came calling.
The Money and Political Weight Gap
The financial footprint of horse racing dwarfs what greyhound racing produced. The racing segment of the U.S. horse industry generates an estimated $26 billion in annual economic impact and supports roughly 1.4 million full-time equivalent jobs across breeding, training, track operations, veterinary services, and tourism. That money buys political influence. Wealthy owners, elite breeders, and large agricultural interests maintain sophisticated lobbying operations in state capitals, and legislators think twice before threatening an industry that deeply embedded in the local economy.
The breeding side shows the scale. Top thoroughbred stallions command stud fees of $250,000 per breeding session in 2026, and their offspring regularly sell for seven figures at auction.5Taylor Made Stallions. Taylor Made Stallions Announces 2026 Stallion Roster and Fees That level of capital investment ties horse racing to land values, agricultural policy, and rural employment. States collect pari-mutuel taxes on every dollar wagered, and licensing fees for racing facilities add revenue that state budgets have come to rely on.
Greyhound racing was always a smaller-scale enterprise associated with working-class gambling rather than elite sport. It lacked the breeding infrastructure, the land use footprint, and the wealthy stakeholder network that make horse racing politically resilient. When welfare advocates pushed, the greyhound industry didn’t have the political capital to push back.
How States Actually Banned Dog Racing
States used several legal tools to phase out greyhound racing while leaving other gambling untouched. The most dramatic was Florida’s Amendment 13, a constitutional amendment that voters approved in November 2018 with 69 percent support. It banned commercial greyhound racing in Florida by the end of 2020 and was drafted so that horse racing tracks and tribal gaming operations were unaffected.6Ballotpedia. Florida Amendment 13, Ban on Wagering on Dog Races Amendment (2018) That surgical approach became a template: target greyhound racing in isolation, protect tax revenue from casinos and horse tracks.
Other states used decoupling laws. Many states originally required gambling venues to host live pari-mutuel racing as a condition of keeping their casino, slot machine, or cardroom licenses. Decoupling removes that requirement, so a venue can stop running dog races while continuing its more profitable gaming operations. Once a track no longer needed live racing to keep its license, the financial reason to continue vanished.
The pace has picked up. Oregon banned greyhound racing in 2022, Connecticut followed in 2024, and Arkansas passed its ban in 2025. States have also started targeting simulcast wagering, where bettors place money on dog races broadcast from other locations. New Hampshire prohibited simulcast betting on dog races in 2024, with the ban taking effect in January 2027. Oregon banned greyhound simulcasting and the processing of internet bets on dog races in May 2025. Those simulcast bans cut off one of the last remaining revenue streams for the few tracks still running.
Where Live Dog Racing Still Operates
Commercial greyhound racing is illegal in 44 states. Five more have no active tracks but have not passed a formal prohibition: Alabama, Iowa, Kansas, Texas, and Wisconsin. That leaves West Virginia as the only state where live greyhound racing still takes place, at Mardi Gras Casino and Resort in Cross Lanes and Wheeling Island Casino and Racetrack in Wheeling. Both run races year-round.
Reform for One Sport, Abolition for the Other
The difference comes down to leverage. Horse racing built a federal legal architecture greyhound racing never attempted. The Interstate Horseracing Act gave it a national wagering system in 1978. The Horseracing Integrity and Safety Act gave it a federally authorized regulator in 2020.3Federal Trade Commission. Horseracing Integrity and Safety Authority (HISA) Oversight Each law made the industry harder to challenge at the state level and easier to defend as a regulated enterprise.
The economic argument reinforced the legal one. An industry generating billions in annual activity and supporting over a million jobs can absorb welfare criticism and respond with regulatory reform. An industry with a fraction of that footprint cannot. When greyhound welfare problems became public, the industry had no federal statute to lean on, no national regulator to point to, and not enough economic weight to persuade legislators that reform was worth the trouble. One sport got tighter rules; the other got shut down.
