How To Measure: Identify the widest/deepest part of your beast’s rib cage/chest. Use a tailors tape/soft tape measure and place the tip of the tape measure at the bottom of the rib cage, behind the forelegs. Wrap it around their back, connecting it to the measure at bottom of their rib cage. Add in 2 fingers perpendicularly between your beast and the measuring device.

*Don’t have a soft tape? Use a shoe string or something similar to wrap around your beast, hold placement with fingertips and measure against a straight ruler.
