Why Do Horses Chew On Wood?

Horses chewing on wood is a common behavior known as wood chewing or cribbing. It can be caused by a variety of reasons, including boredom, stress, or nutritional deficiencies. Wood chewing can have detrimental effects on a horse’s dental health and overall well-being.

One possible reason for wood chewing is insufficient forage or a lack of mental stimulation. Horses may resort to chewing on wood as a way to alleviate boredom or frustration. Providing ample grazing time and offering toys or other diversions can help prevent this behavior.

Stress is another factor that can lead to wood chewing. Horses that are confined to small spaces or have limited social interaction may develop this habit as a coping mechanism. Ensuring a horse has sufficient exercise, turnout, and companionship can help reduce stress-related wood chewing.

Nutritional deficiencies, particularly in their diet’s fiber content, can also contribute to wood chewing. A horse’s instinct to chew on wood may be an attempt to compensate for a lack of fiber. Working with a veterinarian or equine nutritionist to assess and adjust the horse’s diet can address this issue.

Wood chewing in horses can cause dental problems such as excessive wear, tooth breakage, and the potential for splinters. It can also lead to digestive issues if ingested wood obstructs the gastrointestinal tract. Therefore, it is important for horse owners to address wood chewing behavior promptly and implement measures to prevent it.why do horses chew on wood

Understanding Equine Behavior: Why Do Horses Chew on Wood?

When it comes to understanding equine behavior, one common question that arises is why do horses chew on wood? This behavior, known as wood chewing or cribbing, can be a cause of concern for horse owners and caretakers. In this section, we will delve deeper into this behavior and explore the possible reasons behind it.

1. Natural Instincts

Horses have natural instincts that drive their behaviors, and chewing on wood may be one of them. In the wild, horses would often graze on grass and chew on tree barks for various reasons. Wood chewing could be a way for horses to fulfill their natural instinct to forage and explore their surroundings.

Additionally, wood chewing may also serve as a way for horses to alleviate boredom or anxiety. Similar to how humans fidget or chew on pens when feeling restless, horses may resort to chewing on wood as a means of self-soothing or stress relief.

2. Nutritional Deficiencies

Another possible reason for horses chewing on wood is nutrient deficiencies in their diet. Horses require a balanced diet that includes sufficient amounts of fiber, vitamins, and minerals. If a horse’s diet lacks certain nutrients, it may resort to wood chewing in an attempt to compensate for these deficiencies.

To prevent wood chewing due to nutritional deficiencies, horse owners should ensure that their horses are receiving a proper diet that meets all their nutritional requirements. Consulting with a veterinarian or equine nutritionist can help determine if any adjustments need to be made to the horse’s diet.

3. Dental Problems

Dental issues can also contribute to wood chewing in horses. Horses have continuously growing teeth, and if their teeth are not properly aligned or have sharp edges, it can cause discomfort or pain while eating. In such cases, horses may turn to chewing on wood as a way to alleviate the discomfort and promote proper dental wear.

Regular dental check-ups by a qualified equine dentist can help identify and address any dental problems that may be causing the wood chewing behavior.

4. Environmental Factors

The environment in which a horse is kept can also play a role in wood chewing behavior. Lack of adequate turnout or exercise, limited access to forage, or boredom-inducing living conditions can all contribute to a horse resorting to wood chewing as a form of entertainment or stress relief.

To minimize wood chewing caused by environmental factors, it is important to provide horses with a stimulating and enriching environment. This can include offering ample turnout time, providing a variety of forage options, and ensuring social interaction with other horses.

5. Learned Behavior

In some cases, wood chewing can be a learned behavior. Horses are highly intelligent and observant animals, and they may pick up on behaviors exhibited by other horses. If a horse sees another horse chewing on wood and observes that it leads to some form of reward or satisfaction, it may mimic the behavior and develop a habit of wood chewing.

To address learned wood chewing behavior, it is important to discourage the behavior and provide alternative outlets for the horse’s natural instincts and chewing needs. Offering suitable toys or objects designed for equine chewing can redirect their chewing behavior in a more appropriate manner.


In summary, wood chewing in horses can stem from various factors, including natural instincts, nutritional deficiencies, dental problems, environmental factors, and learned behavior. Understanding the underlying reasons behind this behavior is crucial for horse owners and caretakers to effectively address and manage wood chewing. By providing a suitable diet, regular dental care, a stimulating environment, and appropriate outlets for chewing, horse owners can help prevent or minimize wood chewing in their equine companions.

Health Risks and Consequences: Effects of Wood Chewing on Horses

Wood chewing is a common behavior seen in horses that can have detrimental effects on their health. While some horses may engage in this behavior out of boredom or as a result of nutritional deficiencies, it is important to understand the potential health risks and consequences associated with wood chewing.

One of the primary concerns with wood chewing is the damage it can cause to a horse’s teeth. Wood is much harder than the vegetation that horses naturally consume, and excessive chewing on hard surfaces can lead to dental problems such as tooth wear, fractures, and even abscesses. This can cause significant pain and discomfort for the horse, affecting their ability to eat and potentially leading to weight loss.

In addition to dental issues, wood chewing can also pose a risk of gastrointestinal blockages. Horses that chew on wooden fence posts, stall doors, or other structures may accidentally ingest splinters or larger pieces of wood. This can cause obstructions in the horse’s digestive system, leading to colic, a potentially life-threatening condition. Surgery may be required to remove the blockage, adding further stress and expense for the horse owner.

Furthermore, wood chewing can contribute to the spread of infectious diseases. Horses that engage in this behavior may come into contact with feces, urine, or other contaminants present on the wooden surfaces. Bacterial or fungal infections can occur if these pathogens enter the horse’s mouth or open wounds caused by the chewing behavior.

The consequences of wood chewing extend beyond the immediate health risks. In addition to the potential physical damage to the horse, wood chewing can also result in the destruction of property. Horses that chew on fencing or stall surfaces can cause costly damage to these structures, requiring repairs or replacement.

To address the health risks and consequences of wood chewing, it is important for horse owners to take appropriate measures. One approach is to ensure that the horse’s diet is nutritionally balanced, providing them with adequate fiber and minerals. This can help reduce the likelihood of nutritional deficiencies that may contribute to wood chewing behavior.

Providing environmental enrichment and mental stimulation is another key strategy. Boredom is a common trigger for wood chewing, so offering toys, varied turnout options, and social interaction can help alleviate this behavior. Regular exercise and access to grazing or hay can also reduce the horse’s desire to chew on wood.

If a horse continues to engage in wood chewing despite these preventative measures, it may be necessary to use deterrents. Applying products with a bitter taste or odor to the wood surfaces can discourage the horse from chewing. Physical barriers, such as electric fencing or metal grills, can also be used to prevent access to wooden structures.

In summary, wood chewing in horses can have serious health risks and consequences. It can cause dental problems, gastrointestinal blockages, and increase the risk of infections. Taking steps to address the underlying causes and provide appropriate mental and physical stimulation can help reduce wood chewing behavior and protect the horse’s overall health and well-being.

Solutions and Prevention: How to Stop Horses from Chewing Wood

Wood chewing in horses can be a frustrating and potentially dangerous habit. Not only can it lead to damage to fences, stalls, and other structures, but it can also pose a risk to the horse’s health if they ingest toxic substances or splinters. Fortunately, there are several solutions and prevention strategies that can help stop horses from chewing wood.
