White line disease

Veterinary advice should be sought before applying any treatment or vaccine.

White Line Disease

White line disease (WLD) is the separation between the hoof wall and the sole at the white line in the horse's feet. It is caused by keratinolytic fungi. The white line connects the wall of the horse's hoof and the horn of the sole. Several factors can contribute to the development of WLD in the horse; these include poor hoof wall conformation which causes flaring of the hoof wall, imbalance of hoof moisture (such as when environment is too wet or to dry), hoof wall abscess which tracts upward inside the hoof wall, trauma to the hoof wall, laminitis, and irregular shoeing or trimming intervals which allow the hoof wall to grow long.

Symptoms

Dry crumbling horn at the white line
Hoof wall seperation
Problematic to nail on and/or keep shoes
Hoof may sound hollow when tapped

Diagnosis

  • History
  • Clinical signs
  • Physical exam
  • Radiographs

Treatment

TherapiesDetails
Hoof imbalances or wall defects corrected
Entire hoof region debrided to normal, nail-able hoof wall.
Acrylic compounds applied to cover the area of debrided hoof temporarily.

Prevention

  • Ensuring horse's hoofs are trimmed regularly
  • Regularly evaluating horse's diet to ensure they are getting enough nutrients.
