What should instructors regularly check on their horses before lessons?

Instructors should regularly check on their horses' general health and soundness before lessons to ensure the animals are fit for work. This comprehensive approach encompasses various aspects, such as the horse's physical condition, behavioral demeanor, and possible signs of illness or injury. Verifying soundness helps prevent injuries during lessons and ensures the horses are physically capable of performing the required activities safely.

By prioritizing general health and soundness, instructors can address any issues that might affect the horse’s ability to perform effectively or safely. This also fosters a positive learning environment for both the horse and the rider. Neglecting to check only specific areas, such as saddle fit, diet, or coat condition, would not provide a complete picture of the horse's readiness for riding lessons.
