Evaluating a Thoroughbred

Physical Evaluation

• Poor topline (racing condition)

Positive signs:

• Clean legs (no bumps or heat)
• Good bone
• Proportionate build
• Healthy weight with good muscle
• Alert, bright expression

Soundness Considerations

Get a thorough pre-purchase exam including:

• Complete lameness evaluation

Common OTTB soundness issues:

• Arthritic changes in joints
• Old soft tissue injuries
• Bone chips (may or may not affect soundness)
• Navicular changes

Important: Many Thoroughbreds have imperfect X-rays but are completely sound for sport horse careers. Work with a vet experienced with Thoroughbreds.

Temperament Assessment

Questions to ask/observe:

• How did the horse race (front runner vs. closer)?
• How does the horse behave in the stall?
