What 1,513 Euthanasia Cases Reveal About Horse Racing in Puerto Rico

caribbean.equine.advocacy@gmail.com (Chrissy Laughlin) — Sun, 19 Apr 2026 00:12:35 GMT

Between 2019 and 2024, at least 1,513 Thoroughbred racehorses were euthanized at Hipódromo Camarero in Puerto Rico. On its own, that number is significant. But when examined more closely, the data reveals patterns that raise deeper questions about oversight, intervention, and the systems in place to protect equine welfare.

This analysis is based on a structured dataset compiled from documented euthanasia records. The goal is not to sensationalize individual cases, but to understand broader trends and what they may indicate about the current regulatory environment.

A Closer Look at the Data

One of the most striking findings is how frequently euthanasia occurs in close proximity to a horse’s most recent race.

Nearly half (46%) of horses were euthanized within 30 days of their last race
More than one-third (35%) were euthanized within two weeks
Over one-quarter (27%) within one week
Approximately 21% within just three days
7% were euthanized on the same day as their last race

These figures suggest that many horses are continuing to race very close to the point at which they ultimately require euthanasia. While individual cases vary, the consistency of this pattern points to potential gaps in early intervention, monitoring, or decision-making processes.

Patterns, Not Isolated Incidents

It is important to view these findings not as isolated events, but as part of a broader pattern.

When large numbers of horses are euthanized shortly after racing, it raises questions about whether:

Underlying conditions are being adequately identified and managed
Horses are being given sufficient recovery time between races
There are consistent standards guiding when a horse should be removed from competition

These are not new questions within the industry. However, the scale and consistency of the data in this dataset make them difficult to ignore.

Timing and Decision-Making

The timing of euthanasia relative to racing activity is particularly relevant.

A shorter window between a race and euthanasia may indicate:

Acute injury sustained during or shortly after racing
Chronic conditions that have progressed to a critical point
Delayed intervention in cases where deterioration was already evident

In some cases, horses may be competing while managing underlying issues that are not yet fully resolved. Without consistent oversight and conservative decision-making, this can increase the likelihood of negative outcomes.

The Role of Oversight

Effective oversight is central to any racing jurisdiction. It includes:

Pre-race veterinary examinations
Monitoring of horses with known conditions
Enforcement of medication and withdrawal guidelines
Clear criteria for when a horse should be removed from competition

The data does not assign responsibility to any single factor. However, it does suggest that existing systems may not be consistently identifying or acting on risk indicators early enough.

When patterns emerge across hundreds or thousands of cases, it becomes necessary to evaluate whether oversight mechanisms are functioning as intended.

Comparison to Broader Industry Context

In other racing jurisdictions, ongoing efforts have focused on:

Reducing race frequency for individual horses
Strengthening veterinary oversight
Implementing stricter medication controls
Improving retirement and aftercare pathways

These efforts are often driven by the recognition that equine welfare and industry sustainability are closely linked.

The findings from this dataset highlight the importance of aligning local practices with broader industry standards and continuously evaluating outcomes.

What the Data Does—and Does Not—Say

It is important to approach this analysis with clarity and discipline.

The dataset:

Documents confirmed euthanasia cases
Identifies timing patterns relative to racing activity
Provides a foundation for identifying trends

However, it does not:

Determine causation in individual cases
Replace detailed veterinary records
Capture every variable influencing each outcome

Instead, it serves as a starting point for informed discussion and further investigation.

Why This Matters

Equine welfare is not only a matter of ethics, but also of long-term industry viability.

Public perception of horse racing is increasingly influenced by transparency and accountability. Patterns such as those identified in this dataset can shape how the industry is viewed by regulators, participants, and the public.

At the same time, many individuals within the industry are committed to improving outcomes and advancing welfare standards. Data-driven analysis provides an opportunity to support those efforts with clarity and focus.

Moving Toward Solutions

Addressing the patterns identified in this dataset does not require a single solution, but rather a combination of approaches, including:

Strengthening pre-race and ongoing veterinary oversight
Establishing clearer thresholds for removing horses from competition
Reviewing race frequency and recovery time standards
Enhancing transparency around injury and euthanasia reporting
Aligning medication policies with established best practices

These are not abstract ideas. Many have already been implemented successfully in other jurisdictions and can serve as a reference point for continued improvement.

A Data-Driven Approach to Accountability

This analysis is not intended to assign blame, but to support accountability through transparency.

By documenting patterns and making information accessible, it becomes possible to:

Identify areas for improvement
Support informed decision-making
Encourage alignment with established standards

The goal is not to criticize from the outside, but to contribute to a system that prioritizes both performance and welfare.

Conclusion

The euthanasia of 1,513 horses over a five-year period is not a statistic that should be viewed in isolation. When examined more closely, the timing and patterns associated with these cases provide valuable insight into how the system is functioning.

Data alone does not provide all the answers. But it does highlight where questions need to be asked.

Understanding these patterns is a critical step toward improving outcomes, strengthening oversight, and ensuring that equine welfare remains a central priority in Puerto Rico’s racing industry.

Medication Policy and Racehorse Deaths at Camarero

caribbean.equine.advocacy@gmail.com (Chrissy Laughlin) — Sun, 19 Apr 2026 00:07:49 GMT

The Rules Behind the Outcomes

When people look at the 1,513 documented horse deaths at Camarero, the focus is often on the final moment: the breakdown, the injury, the euthanasia decision.

But those outcomes don’t begin on race day.

They begin with policy.

Medication rules determine what can be administered, how much is allowed in a horse’s system, and how close to race day those substances can be used. Those rules shape what veterinarians see, what trainers manage, and ultimately, whether a horse is cleared to run.

Medication policy doesn’t sit in the background. It defines the conditions under which horses compete.

What the Data Actually Shows

The euthanasia dataset tells a clear and consistent story.

Across hundreds of entries, the same injury patterns appear again and again:

Sesamoid fractures
Cannon bone fractures
Fetlock breakdowns
Knee fractures
Suspensory ligament failures
Severe arthritis

These are not random or unpredictable events. They are well-known indicators of cumulative stress, structural fatigue, and underlying pathology.

In many cases, these types of injuries are preceded by warning signs, lameness, inflammation, reduced performance. Signals that something is wrong.

The critical question is whether the system is designed to detect those signals early, or allow them to be managed and suppressed.

Where Policy Enters the Picture

A comparison between ARCI model rules and Puerto Rico’s medication regulations reveals meaningful differences in how drugs are controlled.

Key areas of divergence include:

Higher allowable drug thresholds
Shorter withdrawal periods
Continued use of certain anti-inflammatory medications
Explicit allowance of multi-drug combinations

Individually, these may appear technical. Together, they influence how injury presents and how risk is managed.

Anti-inflammatories and corticosteroids reduce pain and suppress inflammation. That is their purpose. But in a racing environment, they can also reduce the visibility of underlying issues.

A horse that might otherwise show clear signs of lameness can appear sound enough to train, compete, and pass pre-race evaluation.

The Risk Isn’t the Drug. It’s the Timing.

The issue is not that these medications exist.

It’s how they are used.

Shorter withdrawal periods mean horses can race closer to the time when drugs are still active in their system. Higher thresholds mean more of the drug can be present without triggering a violation. Allowing multiple drugs at once increases the overall masking effect.

This combination matters because it changes the margin for error.

When pain and inflammation are suppressed, the body’s natural warning system is muted. Structural problems do not disappear. They simply become harder to detect.

What the Euthanasia Data Reflects

When viewed through this lens, the euthanasia data aligns with what you would expect in a system where detection is more difficult.

The dataset includes:

Horses breaking down during or immediately after races
Horses with known degenerative conditions still in active competition
Injuries concentrated in joints and load-bearing structures
Horses with extensive racing histories continuing to cycle through the system

These are not isolated findings. They are patterns.

And they are consistent with a system where underlying issues may not always be visible at the point of decision-making.

When masking occurs, performance can continue, until the moment it cannot.

Correlation, Not Speculation

No single rule can be tied to a specific death based on these documents alone.

But that is not the standard required to evaluate risk.

What matters is whether the structure of the system creates conditions where adverse outcomes are more likely.

Here, the alignment is clear:

A regulatory framework that allows greater flexibility in medication use
Drugs that directly influence pain and inflammation
An injury profile dominated by conditions those drugs can obscure

This is not speculation. It is a correlation grounded in how these medications function and how these injuries develop.

Why This Matters

This is not about technical compliance.

It is about system design.

Medication policies can either create a protective buffer that prioritizes recovery and detection, or they can narrow the window in which problems are visible.

When that window narrows, risk does not disappear.

It accumulates.

And over time, it shows up in the only place it can: the data.

The Bottom Line

If you want to understand why breakdowns happen, you have to look beyond the track.

You have to look at the rules that shape what is seen, what is managed, and what is missed.

Because the outcomes are not random.

They are the result of the system that allows them.

Opinion: Support the Effort, Demand the Follow-Through

“Is Puerto Rico us or them?”

This response is in reference to a recent article published in the Paulick Report discussing Dr. Stuart Brown’s visit to Puerto Rico and the launch of the Caribbean Racecourse Welfare Group.

Dr. Stuart Brown’s question is an important one. It reflects a willingness to engage, to listen, and to extend expertise where it’s needed. That matters. The involvement of the American Association of Equine Practitioners and the broader veterinary community brings credibility, attention, and resources that Puerto Rico has lacked for years.

There is real value in what Dr. Brown and his colleagues are doing. Showing up, listening to local veterinarians, and creating space for collaboration is a necessary first step. The veterinarians on the ground who have been advocating for change for years deserve to be heard, and efforts that amplify their voices should be supported.

But support should not come at the expense of scrutiny.

I have been working to improve welfare conditions for Thoroughbreds racing in Puerto Rico since 2018, when I joined the board of Caribbean Thoroughbred Aftercare. Beginning in 2019, I participated in multiple meetings with industry stakeholders to present specific, actionable reforms. These were not theoretical ideas. They were operational recommendations designed for immediate implementation.

These recommendations were presented directly to decision-makers, including the Racing Commissioner at the time, veterinary leadership, owners, and representatives of the Confederación and horsemen’s groups.

At their core, the asks were simple:

Use the systems already available
Track horses entering the island
Identify prior veterinary risk factors
Apply that information to pre-race decision-making
Move from reactive to proactive oversight
Improve transparency
Align stakeholders around execution

No new infrastructure was required. The tools already existed.

That includes InCompass, which is now being discussed as a pathway forward. The Puerto Rico racing industry has had access to this system since at least 2019. Its value is not newly discovered. It was clearly presented years ago.

This is not a gap in knowledge. It is a gap in execution.

This is where the involvement of Dr. Brown, the AAEP, and associated groups becomes critically important, not just as collaborators, but as drivers of accountability.

If this effort is going to succeed, it cannot stop at listening sessions or early-stage optimism. It must move quickly into measurable action.

That means asking hard questions:

What specific reforms will be implemented, and by when?
Who is responsible for execution?
How will compliance be monitored and enforced?
What happens if timelines are missed or standards are not met?

Without clear answers, the risk is that this becomes another cycle of discussion without follow-through.

There are also claims within the broader narrative that warrant careful examination.

This is the moment to move from conversation to accountability.

These narratives are designed to inspire confidence, but confidence without accountability is misplaced.

🚩 The assertion that Puerto Rico “consistently adheres to ARCI drug policy” is factually incorrect. Puerto Rico operates under its own medication rules, which differ from ARCI standards. These differences are publicly documented and material. See our comparison here.

🚩 Recent events also raise important questions about oversight and accountability. The recall of Hycoat due to microbial contamination, and reports that it may have been used off-label in intra-articular injections, have been linked to multiple horse deaths and dozens more affected. These are not isolated incidents. They point to breakdowns in clinical oversight, decision-making, and regulatory control at a time when the system is being presented as advancing welfare standards.

🚩 The mention that 34 horses have been successfully rehomed on the island in a short period should be evaluated in context. Placement numbers alone do not define successful aftercare. Long-term outcomes do.

The median household income in Puerto Rico is estimated between $24,000 and $27,000, with average income in the mid-$30,000 range. Only about 6.3% of households earn more than $60,000 annually. Against that backdrop, the cost to responsibly care for a Thoroughbred, conservatively estimated at $500 per month, represents a significant financial commitment relative to typical household income.

This does not make responsible ownership impossible. However, when considered alongside the small percentage of households at that income level, it raises reasonable questions about the scale, speed, and vetting of the placements being reported.

None of this negates the importance of what is happening now. Engagement from respected leaders like Dr. Brown and organizations like the AAEP creates an opportunity that should not be wasted.

But opportunity alone does not create change.

Progress in equine welfare is not measured by meetings, working groups, or early momentum. It is measured by implementation, enforcement, and sustained results.

Do not accept messaging as evidence of progress. The only measure that matters is whether meaningful reforms have been implemented, enforced, and sustained.

That is the standard that should guide what happens next
