Please use a soft tape measure to ensure an accurate measurement.

To ensure a comfortable fit, measure all the way around the lowest part of the dog's neck at top of the shoulders and allow two fingers between the neck and the measuring tape.

Measure the chest at its widest point, all the way around, which is typically right behind the front legs. If the dog has a large girth, going up a size is recommended.

Measure along the dog's backbone from the base of the neck to the base of the tail. (This is where the collar rests to where the tail meets the back/rear-end.)
