To take a wither tracing you will need a flexible wither curve, a pen, and a large, sturdy piece of paper.
You will need to take measurements at 3 different points along the horse’s back. Line “A” is 2-3 inches behind the shoulder blade, Line “B” is at the horse’s last thoracic vertebra, and Line “C” is along the spine from A to B.
First, ensure that your horse is standing square, and that their head is in a natural, forward position.
Fold your tracing curve in half, then lay it 2″-3″ behind the horse’s scapula (shoulder blade) so that it is sitting perpendicular to the ground. Gently for the tracer to mimic the curve of the wither.
Remove the tracer from the withers and lay gently on the large piece of paper. Be careful not to bump or adjust the tracer so that you get an accurate measurement. Trace this onto the paper and label it “Line A”.
Find the point of your horse’s last rib (generally near the top of the flank) and trace along it upward and forward to the last thoracic vertebra. This will be the location of you second tracing.
Lay this second measurement against the same piece of paper. Don’t worry about your line’s overlapping – just ensure that they are labeled! Trace under the curve, and label this line “B”
The third line needed is a profile of the horse’s spine from the first line “A” to the second line “B”. Make sure the curve runs down the center of the spine between the first two points.
Lay this third measurement on the same piece of paper. Label this line “C” and mark “nose” and “tail”
Label the paper with your name, your horse’s name, and the date that the tracings were taken.
