Here is the best way to measure for your new ActiveK9 Lanyard.
If you already have a lanyard lay it flat on a table, measure from the back of the neck to the tip of the clip. This measurement will ensure that your whistle will hang from exactly the same place. If you do not already have a lanyard, use a piece of string to gauge where you would like your whistle to hang from. Lay the string flat on the table and measure. You are measuring the drop from the back of the neck to the tip of the clip.
Your lanyard can be made to 18" (46cm), 20" standard (51cm), 22" (56cm)
