The 10 Most Common Causes of Lameness in Pleasure Horses

Here are 10 of the most common causes of lameness in pleasure horses, based on clinical prevalence in general equine practice (not discipline-specific high-performance horses):

1. Hoof Abscess

• What it is: Infection trapped within the hoof

• Signs: Sudden, often severe lameness; may look like a fracture

• Cause: Bruising, puncture wounds, poor hoof balance

• Prognosis: Excellent with drainage

2. Laminitis (Founder)

• What it is: Inflammation of the laminae inside the hoof

• Signs: Reluctance to move, rocked-back stance, heat in feet

• Cause: Metabolic issues, high sugar intake, systemic illness

• Prognosis: Variable, can become chronic

3. Navicular Syndrome

• What it is: Degenerative condition involving the navicular apparatus

• Signs: Chronic front-end lameness, short choppy stride

• Cause: Multifactorial (conformation, workload, hoof balance)

• Prognosis: Manageable but not curable

4. Sole Bruising

• What it is: Trauma to the sole of the hoof

• Signs: Mild to moderate lameness, sensitive to hoof testers

• Cause: Hard ground, thin soles, poor shoeing

• Prognosis: Good with rest and protection

5. Thrush (Advanced Cases)

• What it is: Bacterial infection of the frog

• Signs: Usually mild, but severe cases can cause lameness

• Cause: Wet, dirty environments

• Prognosis: Good with treatment and management

6. Tendon or Ligament Strain

• What it is: Injury to soft tissues (e.g., superficial digital flexor tendon)

• Signs: Swelling, heat, lameness that worsens with exercise

• Cause: Overuse, uneven footing, poor conditioning

• Prognosis: Variable; requires long rehab

7. Suspensory Ligament Desmitis

• What it is: Injury to the suspensory ligament

• Signs: Subtle or intermittent lameness, performance decline

• Cause: Strain, especially in hind limbs

• Prognosis: Guarded to good depending on severity

8. Osteoarthritis (Degenerative Joint Disease)

• What it is: Progressive joint inflammation and cartilage breakdown

• Signs: Stiffness, worse after rest, improves with light work

• Cause: Wear and tear, age, previous injury

• Prognosis: Manageable, not reversible

9. Hoof Imbalance / Poor Trimming or Shoeing

• What it is: Improper hoof angles or symmetry

• Signs: Chronic low-grade lameness, uneven wear

• Cause: Inconsistent or incorrect farriery

• Prognosis: Good once corrected

10. Back or Sacroiliac Pain

• What it is: Musculoskeletal pain in the back or pelvis

• Signs: Poor performance, reluctance to move forward, subtle lameness

• Cause: Saddle fit, rider imbalance, compensation from limb issues

• Prognosis: Variable; often multifactorial

Key Takeaways

Hoof-related issues account for a large percentage of lameness in pleasure horses.

Many cases are multifactorial, involving both hoof balance and soft tissue strain.

Early detection and proper hoof care are the most effective prevention strategies.
