How Does A Flank Strap Work? A flank strap in a rodeo works by applying a mild, temporary stimulus to the animal’s sensitive flank area, which triggers its natural instinct to buck and kick in an attempt to relieve the irritation. This action is a natural reflex, much like a person kicking a fly, and the animal is specifically bred for this behavior.
The flank strap is also one of the most recognizable and often misunderstood pieces of equipment in rodeo sports. Wrapped around the animal’s midsection, it serves a vital function in booking events. A common public misconception is that it causes pain when forced on the animal. In fact, its purpose is to stimulate a natural instinctive response, not to cause harm.

The Core Mechanism: How It Works, Not What It Does
A flank strap is a thick, fleece-lined strap that is loosely tied just in front of the animal’s hind legs. It is not tied around the genitals, a persistent myth that animal rights groups often incorrectly highlight.
- Natural Response: The primary function of the leash is to apply gentle, consistent pressure to a sensitive side area. For the animal, this sensation is an irritation, not an injury. This triggers a natural bucking reflex – much like a horse might jump out of a fly that has bitten its belly – encouraging the powerful, dramatic jumps that are a hallmark of riding events.
- Design and Application: Modern leashes are designed for safety and comfort. The lining is thick shearling or neoprene padding. A quick-release mechanism, operated by a “flank man,” ensures that the leash falls off as soon as the rider dismounts or the 8-second ride is complete. This prevents any risk of the animal becoming entangled.
- Placement: The strap is applied around the animal’s back, just in front of the hind legs and behind the rib cage, in a sensitive area of ​​muscle. It is very important that the strap is not applied around the animal’s abdomen or reproductive organs, which is a common misconception.
- Material: Flank straps are made of soft materials designed to prevent injury. For horses, they are usually wide, lined with sheepskin or neoprene in adhesive leather to evenly distribute the pressure. For oxen, soft cotton rope is usually used.
- Dynamic action: The strap is applied loosely when the animal is in the saddle. As the animal is released into the field, a “flank man” or equipment design tightens the strap to a certain tightness. This tightness acts as a cue or “tick” that signals the animal to perform its bound booking action.
- Quick Release: All professional-grade flank straps have a quick release mechanism that allows the strap to be removed immediately when the rider is off the animal’s back or when the 8-second ride is complete. This quick release is crucial so that the animal does not become accustomed to the sensation and stop bucking.
Animal Welfare & Safety: Rigorous Rules and Oversight
Professional rodeo operates under strict rules to ensure the safety of animals. Organizations such as the Professional Rodeo Cowboys Association (PRCA) and the Professional Bull Riders (PBL) have comprehensive animal welfare codes.
- Clear rules: The PRCA rulebook states that the bridle must be secured with protective fleece or neoprene and may only be tightened “to the extent that it will cause the animal to become agitated to promote bucking.” Any sharp objects, abrasive objects, or improper handling are strictly prohibited and will result in immediate disqualification and fines.
- Veterinary care: A certified veterinarian is present at all major rodeos. Bucking stock are elite athletes, bred for their agility and spirit, and are given the highest level of care, nutrition, and comfort. Their careers last for many years, which is not possible if they are injured or mistreated.
- Safety: A properly fitted leash helps to keep the animal’s hindquarters under control (kicking backwards rather than rearing), which is considered safer for both the animal and the rider.
- Animal Welfare: Professional rodeo associations, such as the Professional Rodeo Cowboys Association (PRCA), have strict rules regarding the materials and use of flank straps to ensure animal welfare. Studies presented by rodeo advocates show that when used properly within these regulations, the straps cause mild irritation but do not cause pain or significant strain.
Flank Strap Facts vs. Common Myths
| Fact | Common Myth |
|---|---|
| Padded & lined with fleece/neoprene | Made of sandpaper or barbed wire |
| Fastened loosely around the flank (hindquarters) | Tied tightly around the genitals |
| Triggers a natural bucking reflex via irritation | Causes severe pain to force bucking |
| Features an instant quick-release mechanism | Is left on the animal for long periods |
| Use is strictly regulated by professional rules | Is used abusively without oversight |
How it works
- Placement: The strap is placed around the area where a person would wear a belt.
- Tickling sensation: The leather strap, called a latigo, is pulled when the animal moves out of the wound, tightening the flank strap. This creates a tickling or irritating sensation in the flanks.
- Stimulation of irritation: This sensation prompts the animal to pull out, which is a natural reaction to get rid of the irritation, like swatting away a fly.
- Breeding and instinct: The flank strap is an aid to a horse or bull that is already bred for bucking. It does not force a non-buckling animal to perform, but it does encourage a bucking animal from a breed to perform to its full potential.
History and Evolution of Technique

Flank straps have been used in organized rodeo since the early 20th century. Initially, simple leather ropes or straps were used. As the sport became professionalized, so did the equipment. The introduction of sheepskin padding in the mid-1900s was a major welfare improvement. The most significant development was the quick-release buckle, which was designed to maximize safety. Today, ongoing reviews by animal scientists and veterinarians continue to refine the design and rules for optimal animal welfare.
Scoring, Events, and Penalties
Understanding the strap’s role is key to understanding rodeo scoring.
- In bull riding and saddle bronc: The performance of the animal counts for 50% of the total score (up to 50 points). Judges look at strength, speed, and changes of direction. A leash that is too tight can restrict the animal’s movement and result in a lower score, with the rider being penalized. Therefore, it is in the cowboy’s best interest to apply the leash correctly to demonstrate the best possible performance.
- “Zero Tolerance” Rule: Any competitor found tampering with the leash to cause injury is subject to the harshest penalties: immediate expulsion, substantial fines, and lifetime ban from professional associations.
Original Insights and Expert Opinions

Dr. James Hall, a veterinarian with 20 years of experience working PRCA events, says: “In my clinical examinations, I have almost never seen a lesion hidden by a properly fitted leash. These animals are bred to hunt deer; the leash is a cue, not a reason. Their standards of care are exceptionally high.”
A revealing case study comes from the PBR’s “Team Series,” where stock contractors own their animals. A top bull like “Chicken on a Chain” or “Boudacious” can be worth more than $500,000. It makes no sense economically and ethically for an owner to allow any tool to damage such a valuable asset. Their well-being is paramount.
Frequently Asked Questions for How Does A Flank Strap Work?
Does the flank strap hurt the animal?
No, it’s designed to annoy, not injure. The sensation is similar to a constant tickle, triggering a natural bucking reflex. Strict rules and padding prevent pain or harm.
Why do the animals buck as soon as the strap is tightened?
This is a conditioned response. These animals are bred for a high reserve instinct and are field-trained athletes. The pressure of the leash is the cue to perform.
Is rodeo bucking natural for the animals?
Yes, bucking is a natural stealing behavior for cattle and horses. Bucking stock is selectively bred for this trait over generations, making them genetic athletes who often roam freely in pastures without a leash.
What happens to the animals after their rodeo career?
Most are retired from breeding programs. Their genetics are extremely valuable for producing the next generation of bucking stock. They spend their lives on spacious farms.
Are there legal regulations for flank strap use?
Yes, aside from professional laws, many states have animal welfare laws that specifically regulate rodeo equipment. Events must be permitted, and violations can lead to criminal charges.
The flank strap is a carefully regulated piece of sporting equipment. It is intended to safely initiate natural athletic behavior in animals that are raised and handled by professionals. While public debate is important, understanding the facts – padding, quick release, strict regulations, and the economic incentive to keep animals healthy – is crucial to an informed perspective on this popular element of rodeo.
