Veterinary examination can be useful when purchasing a new horse or sometimes for insurance purposes. A full vetting consists of five stages:
Preliminary examination is a complete physical examination including general appearance/condition, teeth, heart, eyes, skin, limbs, feet, joints and back.
Trotting up detects gross abnormalities of gait and action; flexion tests of the joints can be done here.
Strenuous exercise can detect abnormal breathing, heart defects, stiffness or lameness.
Period of rest can reveal breathing and heart abnormalities as resting heart level returns.
Second trot up highlights any locomotor problems induced by exercise and rest. Reflexes are tested by sharp turns and backing up.
On purchasing a new horse we would always recommend that all five stages be undertaken. However, two stages is an option in some circumstances (restricted to stage 1 and stage 2).
