What condition did Barbaro develop due to carrying extra weight on his good leg?

Barbaro developed laminitis as a result of carrying excessive weight on his good leg. When a horse suffers an injury and shifts its weight to the opposite limb for support, the extra stress on that leg can lead to laminitis, a painful condition affecting the hooves. Laminitis occurs when the sensitive laminae, which secure the hoof wall to the underlying structures of the hoof, become inflamed. This inflammation can lead to severe pain and potential structural changes in the hoof.

In Barbaro's case, the added pressure from compensating for the injured leg caused significant strain, ultimately resulting in laminitis. This condition is particularly serious for horses, as it can severely impact their ability to move and can lead to further complications if not managed properly. Understanding the connection between compensatory weight distribution and the risk of developing laminitis emphasizes the importance of monitoring horses closely after they sustain injuries.
