Introduction: Understanding the Behaviour of Wood Chewing in Horses

Wood chewing is a behaviour that can be seen in horses of all ages and breeds. It is the act of gnawing on wood, often of fences, stall walls, or trees. This behaviour can be concerning to horse owners as it can cause damage to property and pose a risk of injury to the horse. Understanding the reasons why horses chew wood is important for preventing this behaviour and addressing any underlying issues.

Common Causes of Wood Chewing in Horses

There are several reasons why horses may chew wood. Nutritional deficiencies, boredom and stress, dental issues, and environmental factors can all contribute to this behaviour. Some horses may engage in wood chewing due to a combination of these factors.

Nutritional Deficiencies and Wood Chewing in Horses

One possible cause of wood chewing in horses is a nutritional deficiency. Horses that are lacking in certain minerals or nutrients, such as salt, vitamins, or minerals like zinc and copper, may be more likely to chew wood. This behaviour is often seen in horses that are on a poor diet or have limited access to pasture. In order to prevent wood chewing caused by nutritional deficiencies, it is important to ensure that horses have access to a balanced diet and any necessary supplements.

Boredom and Stress: Causes of Wood Chewing in Horses

Boredom and stress can also cause horses to chew wood. Horses that are kept in stalls for long periods of time, without sufficient exercise or social interaction, may become bored and engage in wood chewing as a way to alleviate their frustration. Additionally, horses that are stressed due to changes in their environment, such as moving to a new barn or being separated from a companion, may also start to chew wood. Providing horses with ample turnout time, toys, and social interaction can help prevent boredom and stress-related wood chewing.

Dental Issues and Wood Chewing in Horses

Dental issues, such as sharp teeth or mouth pain, can also contribute to wood chewing in horses. Horses that are uncomfortable or in pain may chew on wood as a way to self-soothe. Regular dental check-ups and floating, or smoothing, of the teeth can help prevent dental-related wood chewing.

Environmental Factors and Wood Chewing in Horses

Environmental factors, such as the type of wood available to the horse, can also contribute to wood chewing. Certain types of wood, such as cedar or redwood, may be more appealing to horses due to their taste or texture. Providing horses with appropriate chew toys or access to designated wood chewing areas can help prevent damage to property and reduce the risk of injury to the horse.

Preventing Wood Chewing: Management Strategies for Horses

Preventing wood chewing in horses requires a multi-faceted approach. Providing horses with a balanced diet, ample turnout time, social interaction, and appropriate chew toys can all help prevent wood chewing caused by nutritional deficiencies, boredom and stress, and environmental factors. Additionally, regularly checking horses’ teeth and providing appropriate dental care can prevent dental-related wood chewing.

Treating Wood Chewing in Horses: Veterinary Interventions

If wood chewing persists despite management strategies, veterinary interventions may be necessary. Medications, such as anti-anxiety medications, may be prescribed for horses that are engaging in wood chewing due to stress or anxiety. Additionally, certain dental procedures, such as extractions or treatment for periodontal disease, may be necessary for horses with dental-related wood chewing.

Conclusion: Understanding and Managing Wood Chewing in Horses

Wood chewing is a common behaviour in horses that can be caused by a variety of factors. Understanding the reasons why horses chew wood is important for preventing this behaviour and addressing any underlying issues. Preventative measures, such as providing horses with a balanced diet, ample turnout time, social interaction, and appropriate chew toys, can help prevent wood chewing caused by nutritional deficiencies, boredom and stress, and environmental factors. Veterinary interventions may be necessary for horses with persistent wood chewing despite management strategies.
