Horse White Line Disease: Prevention and Treatment

White line disease is a fungal and bacterial infection of the hoof wall in horses causing separation and potential lameness.

Key Facts

Caused by opportunistic organisms that invade compromised hoof tissue
Wet, muddy environments and neglected hoof care increase risk
Affected horses may be mildly or severely lame depending on extent
Treatment involves debridement to expose infected tissue to air
Most cases resolve with proper farriery and environmental management

Welfare Considerations

Horses with white line disease experience hoof discomfort that worsens with work and weight bearing. Neglected cases can involve large portions of the hoof wall and cause significant lameness. Regular hoof care, dry footing, and early detection prevent most cases from becoming serious welfare concerns.

What You Can Do

Schedule regular farriery visits every 6 to 8 weeks
Keep horse paddocks dry and well-drained
Inspect hooves regularly for signs of separation or odor
Consult a farrier or vet at the first sign of hoof wall issues
Follow through with full treatment protocols including topical antifungals
