Effect of age at training initiation on hoof morphology and lameness in juvenile American Quarter Horses.

Three-year-old American Quarter Horses entering training were more likely to develop forelimb lameness than two-year-olds. This sub-clinical lameness was associated with specific hoof morphology characteristics (decreased foot width, toe length, heel length, and lateral/medial wall height; greater toe angle).
