Understanding Navicular Disease in Horses

Identifying Symptoms of Navicular Disease

Navicular disease, also known as navicular syndrome, presents a range of symptoms that can vary in severity. Horse owners might notice changes in their horse's behavior and performance, which can be indicative of the pain and discomfort associated with this condition. Some of the key signs include:

• Altered Gait and Stance: Horses with navicular disease often shift their weight onto their toes to alleviate pressure on the heels, leading to a shortened stride and a stumbling gait. They may also rest with their weight on the toe or sit back on their hind legs to avoid front foot pressure.
• Heel Sensitivity: When pressure is applied to the hoof, a horse with navicular disease may show signs of heel pain. This can be observed during hoof testing by a farrier or veterinarian.
• Reluctance to Move: Affected horses might display an unwillingness to move forward or lengthen their stride, and they may seem uneven during turns.
• Physical Changes in the Hoof: The heels may appear contracted and smaller due to poor conformation, which can exacerbate the condition.

The Mysterious Onset of Navicular Disease

Navicular disease can be insidious, often developing gradually and going unnoticed until it has caused significant damage. It is not uncommon for a horse to suddenly exhibit severe lameness as the condition reaches an advanced stage. This can be particularly distressing for owners who may not have observed earlier, subtler signs of the disease.

Risk Factors and Affected Breeds

Certain factors increase the risk of navicular disease, including improper hoof care and trimming, which can lead to abnormal hoof growth and poor circulation. Horses that are stall-kept, overweight, or have conformational issues are also at higher risk. Quarter Horses and Thoroughbreds are particularly prone to the condition, with Thoroughbreds often having smaller feet relative to their body size. Even young horses as early as one year old can be susceptible, especially if their diet includes excessive grain intake, which is sometimes practiced on farms aiming for rapid growth for sales or competition.

The Importance of Early Detection and Management

Early detection of navicular disease is crucial for managing the condition and maintaining the horse's comfort and mobility. Regular hoof care, balanced nutrition, and appropriate exercise can help prevent the onset of navicular disease and mitigate its progression. Horse owners should work closely with veterinarians and farriers to monitor their horses' hoof health and address any concerns promptly.

Treatment and Prognosis

While there is no cure for navicular disease, various treatments can help manage symptoms and improve quality of life. These may include anti-inflammatory medications, corrective shoeing, and in some cases, surgical intervention. The prognosis for horses with navicular disease depends on the severity of the condition and the effectiveness of management strategies.

Conclusion

Navicular disease is a complex and challenging condition that requires attentive care and management. By recognizing the signs early and implementing preventative measures, horse owners can help ensure their horses lead comfortable and active lives despite this disease.
